                                      INTRODUCTION




The aim of this Test evaluation Summary is the concentration on the evaluation of the
well-known data modelling and data integration tools, which are currently in use in the
industry. Due to the relation of the project with industrial environments it is obvious that
commodity technologies and industrial tools have been studied and evaluated. A detailed
comparative study focused on the technical features, the suitability of tools for large-scale
industrial use, and the support for legacy data is included.


                                           PURPOSE



As the project deal with industrial environments, commodity technologies and industrial
tools have been studied and evaluated.

Successfully introducing innovations in data interoperability requires interacting with the
legacy standards and middleware that are likely to be in use in corporations and industries
for years to come.

This Test evaluation Summary concentrates on evaluating well-known data modeling and
data integration tools currently in use in the industry. It includes a detailed comparative
study paying particular attention to the technical features as well as the suitability of tools for
large-scale industrial use and support for legacy data standards and standard middleware and
Enterprise Application Integration environments. The types of tools, which have been
considered, are:

              Ontology authoring tools: Protégé, OilEd,

              Data modeling tools: MS Visio, ERWin, SilverRun,

              Enterprise    Application    Integration    Middleware:     MS     BizTalk,    IBM
               WebSphere, Tibco

              UNICORN System

An attempt has been made, not to solely base the comparison on companies literature and
product information, rather relevant product reviews by leading database developers and
power users have been sighted in this report. Some evaluation softwares have also been
downloaded and tested for the comparison.


                                          SCOPE



This report constitutes the Task 2.1of WP2 of COG project, the main objectives of which are
to:

              o Demonstrate the applicability of Grid technologies to industry

              o Realize the concept of an Information Grid incorporating real corporate
                  data

              o Give semantics to corporate data formats including legacy, relational and
                  XML through a detailed mapping to a central ontology.

              o Demonstrate the technological innovation of automatically translating
                  data between data formats on the Grid by way of a semantic mapping to a
                  central ontology

              o Publish a reusable ontology with concepts from discrete manufacturing
                  and specifically automotive

              o Capture best practices in achieving above objectives and document the
                  methodology

              o Disseminate the methodology and results to Europe‘s corporations

              o Reuse the methodology in industry



Based on the results of this task and the study of the technical features of the Coherence
Ontological Modeling Suite, integration strategies and needs for the specified tools will be
analyzed in workpackage 2.2.. Particular attention will be given to integrating these
environments in an industrial setting in order to evaluate how they work seamlessly, achieve

transparent operations for their users and be efficient for use with large legacy and open data
sets. This workpackage will also evaluate the difficulties and possible barriers of deploying
such solutions in an industrial setting.

The results of workpackage 2 will be used in work package 3 for the deployment of the
designed solution.

                             STATE OF THE ART SUM MARY



This survey is divided into four sections, which group different kinds of ontology tools,
namely: Ontology authoring tools, Data modeling tools , Enterprise Application Integration
Middleware and Unicorn system.
Each section includes: Introduction, Short description of the tools to be compared, and
comparison of the tools.



                             ONTOLOGY AUTHORING TOOLS


This group includes tools environments and suites that can be used for building a new
ontology from scratch or reusing existing ontologies. Apart from the common edition and
browsing functionality, these tools usually include ontology documentation, ontology
exportation and importation from different formats, graphical views of the ontology built,
ontology libraries, attached inference engines etc.


                                            PROTÉGÉ
Protégé 2000 is the latest tool in an established line of tools developed at Stanford University
for knowledge acquisition. Protégé 2000 has thousands of users all over the world who use
the system for projects ranging from modeling cancer-protocol guidelines to modeling
nuclear-power stations. Protégé 2000 is freely available for download under the Mozilla
open –source license.


Protégé 2000 provides a graphical and interactive ontology-design and knowledge-base-
development environment. It helps knowledge engineers and domain experts to perform
knowledge management tasks. Ontology developers can access relevant information quickly
whenever they need it, and can use direct manipulation to navigate and manage an ontology.
Tree controls allow quick and simple navigation through a class hierarchy. Protégé uses
forms as the interface for filling in slot values.




CORPORATE ONTOLOGY G RID T M                                                                       - 9 -
The knowledge model of Protégé-2000 is OKBC-compatible. It includes support for classes
and the class hierarchy with multiple inheritance; template and own slots; specification of
pre-defined and arbitrary facets for slots, which include allowed values, cardinality
restrictions, default values, and inverse slots; metaclasses and metaclass hierarchy.


In addition to highly usable interface, two other important features distinguish Protégé-2000
from most ontology-editing environments: its scalability and extensibility.
Developers have successfully employed Protégé-2000 to build and use ontologies consisting
of 150.000 frames. Supporting knowledge bases with hundreds of thousands of frames
involves two components:
       (1) a database backend to store and query the data and
       (2) a caching mechanism to enable loading of new frames once the number of frames
           in memory has exceeded the memory limit.


One of the major advantages of the Protégé-2000 architecture is that the system is
constructed in an open, modular fashion. Its component-based architecture enables system
builders to add new functionality by creating appropriate plugins. The Protégé Plugin
Library contains contributions from developers all over the world.


Most plugins fall into one of the three categories: (1) backends that enable users to store and
import knowledge bases in various formats; (2) slot widgets, which are used to display and
edit slot values or their combination in a domain-specific and task-specific ways, and (3) tab
plugins, which are knowledge-based applications usually tightly linked with Protégé
knowledge bases.


Current backend plugins (and standard backends) include support for storing and importing
ontologies in RDF Schema, XML files with a DTD, and XML Schema files. We have
experimental support for OIL. The development of DAML+ OIL is in its final stages.


Available slot widgets include user interface components to display GIF images, as well as
video and audio. A diagram widgets include user-interface components to display GIF

images, as well as video and audio. A diagram widget allows developers to build elements of
a knowledge base by drawing a diagram in which nodes and edges are themselves frames of
particular types (distinguished by shape and colour).


The most popular type of plugins are tab plugins. Currently available tabs provide
capabilities for advanced visualization, ontology merging and version management,
inferencing, and so on.


The OntoViz and Jambalya tabs, for example, present different graphical views of a
knowledge base, with the Jambalya tab allowing interactive navigation, zooming in on
particular elements in the structure, and different layouts of nodes in a graph to highlight
connections between clusters of data.


The PAL tab provides support for the Protégé Axiom Language. PAL is a subset of KIF that
enables users to express constraints on their data for which the frame formalism itself is not
sufficiently expressive. The PAL inference engine then analyzes the data to tell the users
which constraints the instances in the knowledge base violate and how. The Flora tab (for F-
logic) and the Jess tab provide access to reasoning engines developed elsewhere.


The PROMPT tab provides an environment for managing multiple ontologies. Its
components include tools for ontology merging that help the user to find similarities between
source ontologies and to merge the ontologies; for ontology versioning, which automatically
finds a structural ―diff‖ between versions of an ontology; and for extracting semantically
complete subparts of an ontology and rearranging frames in different linked ontologies.


The UMLS and WordNet tabs enable users to import and integrate elements of the large on-
line knowledge sources into their ontologies




                                           OILED




CORPORATE ONTOLOGY G RID T M                                                                     - 11 -
Oiled is a simple editor that allows the user to create and edit OIL ontologies. The main
intention behind OilEd is to provide a simple, freeware editor that demonstrates the use of,
and stimulates interest in, DAML+OIL. OilEd is not intended as a full ontology
development environment-it will not actively support the development of large-scale
ontologies, the migration and integration of ontologies, versioning, argumentation and many
other activities that are involved in ontology construction. It should, however, provide
enough to allow the basic construction of OIL ontologies and demonstrate the power of the
connection to the FaCT reasoner.


Oiled has been built by The Information Management Group, Department of Computer
Science, University of Manchester. The original development of OilEd was supported by
Interprice GmbH and the Free University of Amsterdam.


The knowledge model of OilEd is based on that of DAML+OIL, although this is extended
by the use of a frame-like presentation for modeling. Thus OilEd offers a familiar frame-like
paradigm for modeling while still supporting the rich expressiveness of DAML+OIL where
required classes are defined in terms of their superclasses and property restrictions, with
additional axioms capturing further relationships such as disjointness. The expressive
knowledge model allows the use of complex composite descriptions as role fillers. This is in
contrast to many existing frame-based editors, where such anonymous frames must be
named before they can be used as models.


The main task that OilEd is targeted at is that of editing ontologies or schemas, as opposed to
knowledge acquisition or the construction of large knowledge bases of instances. Although
functionality is provided that allows the definition of individuals, this is primarily intended
for the definition of nomimals, which are used in the DAML+OIL one-of construction.


A key aspect OilEd‘s behavior is the use of the FaCT reasoner [Horrocks et al, 99] to
classify ontologies and check consistency via a translation from DAML+OIL to the SHIQ
description logic. This allows the user to describe their ontology classes and have the
reasoner determine the appropriate place in the hierarchy for the definition.

The DAML+OIL RDF Schema (March 2001)XXXX is used for loading and storing
ontologies. In addition, the tool will read and write concept hierarchies in pure RDF and will
render ontology definitions as HTML for browsing and as SHIQ for later classification by
the FaCT reasoner. Concept hierarchies can also be rendered in formats readable by AT&T‘s
dotty tool. XXXXX


The DAML Language is being developed as an extension to XML and the Resource
Description Framework (RDF). The latest release of the language (DAML+OIL) provides a
rich set of constructs with which to create ontologies and markup information so that it is
machine readable and understandable.




                                             Comparison

An important aspect when analyzing a tool is its software architecture and tool evolution.
Both OilEd and Protégé 2000 have standalone architecture. While Protégé 2000 can be
extended with Plugins, OilEd cannot be extended. An other weak point of OilEd is that it
uses files for storing ontologies while Protégé 2000 uses DBMS (JDBC). In addition, none
of them provide any backup management functionality.


Interoperability with other development tools, merging tools, information systems and
databases, as well as translations to and from some ontology languages, is another important
feature in order to integrate ontologies in applications. The interoperability with other
development tools for OilEd is FaCT, while for Protégé 2000 are PROMPT, OKBC, JESS
and FaCT. OilEd translates to OIL, RDF(S) and DAML+OIL languages, from OIL, RDF(S),
DAML+OIL SHIQ and dotty HTML languages. Protégé 2000 translates to XML, RDF(S),
XML Schema languages from XML, RDF(S), XML Schema, FLogic, CLIPS and Java
HTML languages.


From the KR paradigm point of view, there are two families of tools: description-logic based
tools such as OilEd and other tools such as Protégé 2000 which allow representing




CORPORATE ONTOLOGY G RID T M                                                                     - 13 -
knowledge following a hybrid approach based on frames and first order logic. Additionally,
Protégé 2000 provides flexible modeling components like metaclasses. However, none of the
tools analyzed includes: methodological support, project management facilities, ontology
maintenance and they only provide a little support for ontology evaluation.


Before selecting a tool, it is also important to know which inference services are attached to
it. This includes: built-in and other inference engines, constraint and consistency checking
mechanisms, automatic classifications and exception handling, among others. OilEd
performs inferences using the FACT inference engine and Protégé 2000 uses PAL. OilEd is
the only one performing automatic classifications because it is based on description logic
languages. Finally none of the tools provide exception-handling mechanisms.


Related to the usability of tools only in Protégé 2000 there are graphical editors for the
creation of concept taxonomies and relations. In addition, there is the ability to prune these
graphs and perform zooms of parts of it. Finally, none of them allows any kind of
collaborative working, while both of them provide libraries of ontologies.
The following table shows the result of comparison in terms of the requirements for the
ontology evolution

The basic functionality of each authoring tool is specified as a set of elementary ontology
changes. Thus, all allows allow such modifications. Even though composite changes allow
an ontology engineer to update an ontology without having to find the right sequence of
elementary modifications, most of the existing ontology tools do not include composite
changes. Most of the existing systems for the ontology development provide only one
possibility for realising a change, and this is usually the simplest one. For example, the
deletion of a concept always causes the deletion of all its subconcepts. It means that users are
not able to control the way changes are performed (supervision). Moreover, users do not
obtain explanations why a particular change is necessary (transparency).


Furthermore, there is no possibility to undo effects of changes (reversibility). Protégé has
Edit menu with Undo/Redo options, but they are disabled. Regarding the auditing
requirement, OilEd has the activity log. However, it records connections to the reasoner, not
all ontology modifications. Protégé also has the command history option, but it is useless,
since it is disabled. As known to authors, none of the existing systems for ontology
development and maintenance offer support for (semi-)automatic ontology improvement,
even though it makes the ontology easier to understand and cheaper to modify. Most of the
existing ontology authoring tools have a very similar layout. They are ergonomically correct
to minimise human errors. Moreover, all tools can detect logical conflicts (verification), but
they do not provide enough information to analyse the sources of conflicts. However, none
of the tools provide the means to answer to the questions such as how, why, what if, etc.
(validation).



                                             Conclusions

In summary, a lot of ―similar‖ ontology development tools exist for the building of
ontologies, but neither do they interoperate nor do they cover all the activities of the
ontology life cycle (just design and implementation). The lack of interoperability between all
these tools provokes important problems when integrating an ontology into the ontology
library of a different tool, or if two ontologies built using different ontology tools or
languages are integrated using merging tools.

                                          MS VISIO



Microsoft Visio is a stand-alone diagramming solution that helps people visualize and
communicate ideas, information, and systems.
Visio has three main roles:
              Complements        Microsoft   Office   Business     professionals   can   create
               information-rich diagrams that complement and extend the work they do in
               Office programs.
              Facilitates technical design, deployment, and maintenance Technical
               professionals can diagram and document ideas, information, and systems to
               facilitate IT deployments, extend the use of developer tools, and even
               document facilities layouts and engineering plans.
              Enables development of custom visual solutions Visio provides the ability
               to create custom shapes and stencils to support organizational standards and
               can be used to build wide-scale custom visual solutions.
Within each of these roles, Visio provides three key benefits. These benefits include the
ability to 1) easily make an impact by quickly creating and sharing professional-looking
diagrams, 2) understand ideas, information, and systems through a broad range of task-
specific solutions that integrate with other Microsoft products, and 3) benefit from the
diagramming standard using a single, customizable diagramming program that can be
deployed across the organization.


Easily Make an Impact
Visio provides the tools you need to quickly create and share professional-looking diagrams.
The familiar Microsoft Office environment makes Visio easy to learn and use and with Visio
you don‘t need drawing expertise to create professional-looking diagrams. You can assemble
diagrams quickly and easily by dragging pre-defined Microsoft SmartShapes® symbols from




CORPORATE ONTOLOGY G RID T M                                                                       - 16 -
stencils onto the drawing page. Built-in borders, backgrounds, and color schemes help you
add a professional look to your diagrams. Easily share diagrams by copying them into Office
documents or saving them as detailed Web pages.


Understand Ideas, Information, and Systems
Visio supports a broad range of task-specific diagram types, from process flows and
organization charts, to office and building layouts, to network, web, and database topologies,
and more. Many diagrams can be generated automatically from data stored in Microsoft
Excel, Exchange Server, Microsoft SQL Server, and other common data sources. Store
data in custom property fields and generate reports, or export Visio diagrams to common
exchange formats.


Benefit From the Diagramming Standard
Visio provides a single, customizable diagramming standard that is easy for organizations to
deploy and maintain. Visio products share a common file format, so users can exchange
diagrams across the organization, regardless of which Visio product they use. Visio Standard
and Visio Professional are based on the Visio diagramming engine, which can be used to
develop custom visual solutions. Plus, organizations can perform efficient wide-scale
deployments with tools for installing and maintaining Visio on thousands of desktops.
The Visio family includes two products designed to meet the needs of specific groups of
users:


Microsoft Visio Standard         provides diagramming solutions         that   help   business
professionals—such as project managers, sales and marketing professionals, HR personnel,
administrative staff, and others—visualize and share information about the people, projects,
and processes they work with every day.


Microsoft Visio Professional helps technical professionals—IT, developer, and engineering
professionals—visualize existing ideas, information, and systems and prototype new ones.
Visio Professional also includes the business diagramming solutions found in Visio
Standard.

Visio products share a common file format, so users can exchange diagrams, regardless of
which Visio product they use. Visio Standard and Visio Professional also include the Visio
diagramming engine for developing custom visual solutions.


Design Goals
The design goals for Visio 2002 correspond to the three themes above and include the
following: increased visual impact, tighter integration with other applications, and improved
deployment, maintenance, and customization.
Visio 2002 helps you easily make an impact with tools for creating better-looking diagrams
than ever and sharing them in the context of your everyday business communications. The
Visio 2002 product line is also easier to learn and use, with many classic Office features, as
well as new features shared with Office XP. And a number of online resources make it easier
to increase your productivity.
Lines and text are smoother than in previous versions, and gradient fills appear clearer when
viewed electronically. Visio now supports over 16 million colors per document. In addition
it provides built-in access to clip art installed with Microsoft Office, as well as tens of
thousands of images, sounds, and videos available online. You can enhance Visio diagrams
by importing images or photos directly from a scanner or digital camera and crop, group, or
change the fill, border, shadow, or transparency of imported graphics within Visio.
Diagrams saved as Web pages include a custom properties viewer, built-in navigation, and
improved hyperlink positioning. Multiple hyperlinks can be displayed for a single shape.
Double-click a diagram within an Office document, and get access to more Visio tools for
making updates and revisions.
The Choose Drawing Type dialog opens when Visio is launched to help users visualize and
access the appropriate diagram template. The Getting Started Tour provides an introduction
to Visio, a sample diagram library, and the basic steps involved in creating Visio diagrams.
Answer Wizard Help enables users to type questions directly into the Ask a Question box. A
list of related Help topics appears, including links to new and updated topics on the Web.
The Find Shape tool provides search capabilities for installed shapes as well as additional
shapes available on the Web. Download new shapes by dragging them from the results pane
onto the page. The Find Shape tool provides search capabilities for installed shapes as well




CORPORATE ONTOLOGY G RID T M                                                                     - 18 -
as additional shapes available on the Web. Download new shapes by dragging them from the
results pane onto the page. The Pan and Zoom, Custom Properties, and Drawing Explorer
windows can be merged into a single, page-tabbed window and docked in the stencil pane to
provide additional workspace. Users can now search diagrams for information contained in
custom properties, shape names, and user-defined cells, in addition to shape text.
Visio has the new Office XP new look for improved usability and overall experience. Menus
include the same personalization options that make Office applications easy to learn,
prominently featuring the most-used items and keeping others easily accessible. The task
pane helps users open or start documents, view the contents of the clipboard, perform
searches, or insert clip art (Office XP required for clip art integration). Common Office tools
such as AutoCorrect behaviour, familiar keyboard shortcuts, and the Office spelling checker
are now built in to Visio.
Visio articles, tips and tricks, product updates, and add-on solutions on the Microsoft Office
Tools on the Web site help business users increase their productivity. Technical Visio
articles are available through MSDN®, TechNet, and the Microsoft Knowledge Base.


More Integrated
Individual Visio solutions help you better understand ideas, information, and systems
through tighter integration with other products and technologies. Many solutions have been
improved to be easier to use and to help you work more effectively.
Visio Standard and Visio Professional import dates and tasks from Microsoft Project to
create Visio timelines and Gantt charts. Export dates and milestones in a timeline to create a
Gantt chart, and vice versa. Display an unlimited number of custom properties on
organization charts. Users can change which properties are displayed after the diagram has
been generated. Create maps of small areas and other locations requiring detailed
documentation. New shapes represent curved walls and office cubicles. Resize office layout
shapes using new dimension labels or by specifying custom property values. Doors and
windows automatically fall into place when dropped on a wall shape. Individual CAD
entities can be converted into Visio shapes.




CORPORATE ONTOLOGY G RID T M                                                                      - 19 -
In Visio Professional new shapes represent Exchange objects in Microsoft Active
Directory. Users have increased control over discovery and layout. A new List window
enables easy navigation by displaying Web site elements in a tree view. Users can generate a
complete report of all the links in a Web site, including broken links. The reporting tool can
identify changes in a Web site since it was last diagrammed. Users can work more quickly
by adding new fields consecutively to database tables or software classes. Users can reverse
engineer and diagram schema for SQL Server 2000, in addition to other databases. Building
a database diagram from the Tables window is faster than in previous versions. Also, users
no longer need to drag tables from the Tables window to create a diagram after reverse
engineering a database Users can reverse engineer and diagram Microsoft Visual Basic® 6
and Visual C++® 6 projects. Support for Visual Basic 7, Visual C++ 7, and Visual C# will
be provided through a service release when Microsoft Visual Studio®.net becomes available.
New shapes represent curved walls; any flat wall can be transformed into a curved wall.
Users can easily change the curvature of curved wall shapes. Visio automatically cleans up
wall intersections, reducing the amount of cleanup required in creating building plans. Users
can automatically populate floor plans with data stored in Active Directory, Exchange, Excel
spreadsheets, Access databases, or other ODBC-compliant data sources. Visio enables users
to automatically assign colors to shapes, such as offices in a floor plan, based on custom
property values. Visio now enables users to see all model space views supported by
AutoCAD paper space. The process engineering solution now displays component
information in the Custom Properties window, eliminating the need for an external database.
Engineers can manually tag process-engineering components and selectively retag them.
Tags can also be generated based on component custom property data. Users get enhanced
control of pipe layout with support for junctions, as well as splitting and healing of pipe
segments by valves and other process engineering components.
Visio features several improvements that make it a stronger diagramming standard than ever.
A streamlined product line simplifies purchase decisions for organizations, while other
improvements enable improved customization and tighter interoperability. Finally, familiar
deployment technologies enable organizations to deploy and maintain Visio on thousands of
desktops.

Visio Standard and Visio Professional are available in 13 languages: English, French,
German, Japanese, Korean, Italian, Spanish, Brazilian Portuguese, traditional Chinese,
simplified Chinese, Dutch, Swedish, and Danish. Visio Network Tools is available in
English, French, German, and Japanese.
The new XML file format enables interoperability with other XML-enabled applications and
facilitates storage and exchange of diagram-based information, including data not associated
with a page or shape Over 90 new Automation properties and methods provide access to
more Visio diagram data. Visio enables developers to extend and enhance Visio
programmatically through COM add-ins. Developers can extend and enhance Visio
functionality using built-in Visual Basic for Applications (VBA) 6.3. Microsoft
Authenticode® technology allows developers to digitally sign the VBA projects in their
solutions using a digital certificate that identifies the developer as a trusted source. If a
signed project has been altered, a user can choose to disable macros in a Visio document.
Administrators and/or users have the option of removing Visual Basic for Applications from
Office installations on a user, group, or organization-wide basis.
The Auto Update utility analyzes a user‘s Visio installation, recommends relevant updates,
and makes them immediately available for download and installation. Users can choose to
save their current files at the time an error occurs in an application. As a result, users spend
less time recreating their diagrams. For added assurance and diagnostic help, users can
prompt Visio to automatically report application errors to Microsoft. Users can choose to
safely shut down a non-responding application while initiating recovery of the document.
Users can choose how often files are automatically saved. If an error occurs, the recovered
file is opened, and users have the option of discarding the file, saving it over the original, or
saving it as a separate file.
Like Office, Visio can be deployed using Windows® Installer technology. Windows Installer
simplifies desktop management. End users can install additional Visio features on demand—
features are added only as needed or as disk space allows. IT administrators can use Install




CORPORATE ONTOLOGY G RID T M                                                                        - 21 -
on Demand to determine which features to deploy to different groups of users, thus
improving manageability. In addition, the self-repair feature reduces support costs—Visio
detects and fixes missing or corrupt files, so users don‘t waste time troubleshooting. Visio
uses the Office Installation Wizard, which provides control over customized installations,
including silent and unattended installations. Systems Manager Server (SMS) support
simplifies installation. Organizations can create packages for automatic deployment to
specified user groups on the local network and at remote sites System administrators can
more effectively install and run Visio in a secure Windows environment. Features such as
install on demand and detect and repair are now accessible to users without local
administrator privileges. Multiple, concurrent users will benefit from improved Terminal
Server support. This Web-based tool guides administrators through specific scenarios to
ease deployment efforts.

                                            ERWIN


While ERwin is strictly a data modeling tool, Logic Works also publishes BPwin, an IDEF
process tool, and a number of products related to the design, coding, and implementation of
database application systems. ERwin and BPwin both connect to Logic Works' ModelMart
repository product for shared model storage and access.

While there is still no way to perform selective de-normalization, the new ―logical only‖
property on entities, attributes, and relationships allows substantial differentiation of logical
and physical models. Views are provided, albeit incompletely, in an attractive and simple
approach. The primary editor interfaces have been refreshed and simplified.

ERWin has introduced separate logical and physical models. This is accomplished by
treating the two model forms as different representations of the same content.




For example, many-to-many relationships now appear immediately in the physical model as
associative tables when Physical Model is selected from the menu drop-down list. An
associative table can have columns added which will not be represented in the logical many-
to-many relationship. Logical Model can also be chosen to permanently convert the
relationship into an associative entity.

The biggest benefit of the separation of logical and physical diagrams is probably how the
various editors are simplified. Since there are fewer properties to be shown (i.e., either
logical or physical, but not both), the new editor formats are less cluttered. However, this
separation makes no provision for meaningful de-normalization, which is the only real
reason for having separate diagram forms. Columns cannot be moved or replicated in the



CORPORATE ONTOLOGY G RID T M                                                                        - 26 -
physical with any link to their source attributes in the logical model. Furthermore, since both
logical and physical models work from the same underlying metadata, logical data cannot be
propagated into multiple physical models (for different database products, configurations, or
trial versions) without a crude "save as" or copy. Either of those, of course, will break the
links of the new model from its origin.

Logical Only / Physical Only Properties

ERwin 3.5 adds a new detail feature buried as a checkbox on the object definition editors. A
logical model object (entity, attribute, relationship) can be specified as Logical Only. This
will suppress that object in the physical model. In a symmetrical fashion, there is a Physical
Only property for tables, columns, and physical relationships (foreign key references). These
setting options may seem trivial but they provide several valuable capabilities. Objects can
be marked as Logical Only, if they are in process and not yet ready for exposure to the real
world. On the physical side, Physical Only provides a poor man's de-normalization if you
want to manually represent column moves and replications without forcing the same form in
the logical model. This is also useful to model technical columns and tables from the
physical side without cluttering up the logical side.

Views

It is slick and simple: just grab the View table tool from the tool box, drop a view symbol
into a physical model and connect it to its source tables with the View relationship tool. The
resulting view is immediately and dynamically populated with columns from the source
tables.

Unfortunately, several of the most important elements in a view are NOT provided. The
WHERE clause is left to the user to code. There is no provision for GROUP BY, HAVING,
or ORDER BY, all of which are fundamental to any SQL query.



Application

Erwin provides imported entry of entity and attribute names directly on the diagram surface.
One can click a new entity onto the canvas and just start typing, go back into the editors later
to add the details. This is very simple and natural for free-form ―white-board‖ style input. Of

course ERWin still allows very easy attribute movement with the toolbox hand icon. One
can navigate from the attributes of an entity to the descriptive properties of that entity but not
the other way around. Adding an attribute in the editor imposes another dialog box on top,
rather than accepting entry into a grid or list. The multiple Display levels and Editor styles
remain Erwin‘s most confusing aspects.

Every window is organized differently. Many options, even important concepts, only appear
as obscure buttons nested several windows deep. Some are now only available from the right
mouse menu. There is no apparent design pattern or template from which new features are
added or old ones enhanced.

Erwin‘s manuals and help are generally excellent, well-organized, well written, and
providing extensive discussions of concepts with examples. Feature creep has gotten ahead
of the indexing (both printed and on-line) so it is often a goose chase to look up a specific
feature. But the explanation will probably be clear and complete.



Usability

ERwin has taken a beating recently on this issue and consequently the company that provide
it has done substantial rework on the interface for 3.5. ERwin provides improved entry of
entity and attribute names directly on the diagram surface. You can click a new entity onto
the canvas and just start typing. Go back into the editors later to add the details. This is very
simple and natural for free-form "white-board" style input. Of course ERwin still allows
very easy attribute movement with the tool box hand icon.


Nonetheless, we think that ERwin is still neither pretty nor friendly once you dive into the
dreaded editors. You can navigate from the attributes of an entity to the descriptive
properties of that entity but not the other way around. Adding an attribute in the editor
imposes another dialog box on top of the one you're in, rather than accepting entry into a
grid or list. The multiple Display levels and Editor styles remain ERwin's most confusing
aspects.

On the other hand, ERwin's manuals and help are generally excellent - well organized, well
written, and providing extensive discussions of concepts with examples. Feature creep has

a specific feature. But when you find it, the explanation will probably be clear and complete.


                                        SILVERRUN
SilverRun is an integrated business process and data modelling solution for handling an
enterprise's entire portfolio of models - from business process models to conceptual, logical
or physical data models, application packages or data warehouse. This breadth of
functionality is delivered in a highly intuitive, easy-to-learn, easy-to-use graphical
environment. SilverRun products are available on Microsoft Windows, OS/2, Macintosh and
SUN Solaris.


SilverRun products exist in both standalone (SilverRun Professional series) and team
modelling configurations (SilverRun Enterprise Series) to support enterprise-level modelling
efforts. The SilverRun Professional Series includes four modules for the analysis stage of the
application development life cycle: Entity Relationship Expert (ERX), Relational Data
Modeller (RDM), Business Process Modeller (BPM), and Workgroup Repository Manager
(WRM). The SilverRun Enterprise series, which includes an on-line, relational database
repository, supports ERX, RDM and BPM in a team modelling, repository-based
environment.


Furthermore, SilverRun is a large and deep set of tools for database modeling and
engineering. At the moment SilverRun is perhaps uniquely positioned among CASE tools.
Yet SilverRun offers serious enterprise features generally found in much more expensive
server based tools (e.g., ADW, LBMS‘s Systems Engineer). SilverRun integrates the three
classic fundamental data design components based on a common presentation approach and
shared design definitions:




CORPORATE ONTOLOGY G RID T M                                                                      - 29 -
   BPM Module: Discovery of requirements, definitions, and structures via data flow
diagramming.
   ERX Module: Conceptual modeling via Chen style Entity-Relationship diagrams.
   RDM Module: Advanced relational schema design and DDL generation.


Each of these three modules is a separate product, licensed per seat. Since the per module
cost is about the same as the total cost of Erwin, SilverRun can be somewhat more
expensive, depending on configuration and user population. Nonetheless the cost difference
alone is moderate and hardly a deterrent to enterprise scale users who may desire
SilverRun‘s benefits.


In addition, an optional Enterprise version of SilverRun (RDM only to date) joins the big
leagues by working directly over a relational database dictionary. Standard versions capture
a model snapshot in a proprietary file local to the user. A product facility is provided to
manage the reconciliation of multiple models. The Enterprise version, on the other hand,
displays each object live from its shared RDBMS dictionary (in Oracle, Sybase,…), which
handles locking, updates, and global refresh at the object level. Based on its solid foundation
in methodology, depth of features, and modular integration, SilverRun is a strong leader in
the CASE data-modeling field.


SilverRun‘s style is bulky, clumsy, and slow to the point that it inhibits, rather than enables,
design inspiration. Menus are very long and intimidating without obvious choices. Tool
pallets contain overlapping and confusing icons. Accessing graphic objects requires
knowledge of specific tool behaviors. ―Connectors‖ are defined separately from
―Directions‖. A number of its internal rules are only enforced by batch procedures, rather
than as real-time validations. SilverRun understanding is encumbered by jargon unknown in
the standard lexicon of data modeling.


At a more general level, the methodology framework imposed by SilverRun‘s ERX module
is out of date and incomplete. The Chen style Entity-Relationship modeling in the ERX
module forces the dated notion of ‗relationships‘ as objects separate and distinct from




CORPORATE ONTOLOGY G RID T M                                                                       - 30 -
entities-a concept which has been discarded by most practitioners in favor of the more
streamlined and understandable Information Engineering technique.


SilverRun‘s sub-typing is implemented only at the physical level (RDM ―Choises‖) and
offers no flexibility in mapping conceptual sub-types into normalized or de-normalized
tables. Candidate keys are not supported, although their common weak side effect of
―alternate keys‖ are. There is no facility in the ERX module to model purely conceptual
entities, which externalize an attribute definition without generating a table.


SilverRun provides multi-platform desktop support, excellent on-line help, extensive printed
documentation, good user support policies and a robust, reliable code that performs well.



                                        COMPARISON
It is difficult to say which of the tools that we have described before are the best data
modeling tools. Every tool has its advantages and disadvantages.
While performing some tests, ERwin actually shut down abnormally, losing all unsaved
work. The simplest way to cause this was to create a domain in the Explorer view
underneath an existing domain while the list was sorted hierarchically. Apparently due to an
error in the code, a ―ghost‖ domain would be created at the top level. Any attempt to delete
the extra domain resulted in immediate shut down. A number of functions either didn‘t work
at all or didn‘t work as indicated in the documentation. For example, drawing a reference
from a parent ―entity‖ to a child is supposed to ―auto-migrate‖ the parent PK column to
become a child FK column, if the option is turned on in the model properties. For identifying
references, it worked fine, but for non-identifying references, nothing migrated. ERwin has
always had a slightly more cumbersome interface, with a general lack of graphic
functionality. The interface has improved in 3.5 version, adding a number of very nice
features, such as the Explorer view and graphic. However, the general impression of the
interface is still clumsy with graphic anomalies and unstable code. The user interface is the
first experience users have with the product, therefore, it cannot be overemphasized how
important a robust user interface is to the overall acceptance of the tool.

However, Visio has a more sophisticated user interface and functions that are easier to find
and use for the novice. With its advanced control over graphics and its stronger reporting
facility, Visio produces better quality documentation than Erwin and SilverRun.
Additionally Visio is including reverse engineering and DDL creation. It‘s also one of the
few tools that supports object role modeling (ORM) for conceptual design. ERwin seems to
lack some of the higher-end documenting capabilities to be expected in an enterprise-level
modeling tool. Additionally, ERwin           has   some very compelling features              with
denormalization management and better naming convention tools. SilverRun is a suite of
tools designed to support ER and business process modeling, as well as UML and code
generation and can support high levels of integration into third party tools. In conclusion we
can say that both of these data modeling tools are very popular and provide the user with a
many useful functions.

                                        MS BIZTALK

Biz Talk Server 2002 lower the cost of implementing integration solutions by reducing the
complexity of enterprise application integration. It provides organizations with the server,
tools, adapters, and vertical accelerators needed to integrate and automate their business.
BizTalk Server adapters. BizTalk Server adapters are additional software components that
enable BizTalk Server to integrate with third-party applications from companies like SAP,
J.D. Edwards, and PeopleSoft. Microsoft produces two adapters which can be licensed, one
for MOSeries and one for SAP. It also provides an adapter which can be downloaded for
Web Services. In addition, third-party companies provide hundreds of additional BizTalk
Server adapters.
BizTalk Server accelerators. Microsoft offers three BizTalk Server accelerators—
Microsoft BizTalk Accelerator for HIPAA, Microsoft BizTalk Accelerator for Suppliers, and
Microsoft BizTalk Accelerator for RosettaNet
Benefits
BizTalk Server provides companies with three main benefits:




CORPORATE ONTOLOGY G RID T M                                                                         - 32 -
      Integration of enterprise applications. Today's agile businesses need to make
       better decisions more quickly. By achieving a unified view of their data and
       applications both within their organization and with their business partners, these
       business can increase their revenues and decrease their cost of operation. Data and
       transformation services and the application integration features in BizTalk Server
       2002 can provide businesses with the tools they need to achieve this unified view.
      Automation of business processes. To remain agile, businesses must be able to
       integrate their data, applications, and business partners in an automated, predictable
       way so they can achieve the return on investment that application integration can
       bring. BizTalk Orchestration Designer and BizTalk Orchestration Engine provide
       organizations with business process automation, enabling their businesses to run
       predictably.
      Development of operational excellence. To realize real return on investment, it
       must be possible to rapidly deploy and easily manage an integration solution. This
       flexibility can reduce the cost and complexity associated with application integration.
       BizTalk Server 2002 introduces SEED, a revolutionary new technology for
       automating the integration of business partners over the Internet.
Functionality
BizTalk Server enables businesses to achieve application integration through five key
processes: document transport and routing, data transformation, application integration,
process automation, and scalability and manageability services. Each process is achieved
through receive functions, channels, ports, schedules, and tools.
               Receive functions are the starting point for documents submitted to BizTalk
                Server.
               Channels modify the structure of these documents as well as manage
                encryption, digital signatures, and logging.
               Messaging ports send documents to schedules or to external organizations
                and trading partners.
               Schedules orchestrate business processes.
               BizTalk Server 2002 tools enable the receive functions, channels, messaging
                ports, and schedules to run.




CORPORATE ONTOLOGY G RID T M                                                                     - 33 -
Receive Functions
BizTalk Server is capable of receiving documents submitted through a wide variety of
medium, including Internet standard technologies such as HTTP, SMTP and SOAP, as e-
mail attachments, through the message bus, programmatically through exposed API‘s, and
through adapter components. BizTalk Server receive functions monitor HTTP, MSMQ
message queues, and file locations for incoming business documents. They are responsible
for submitting the received documents on to a channel, the second step in the process.
BizTalk Server Administration components are used to configure receive functions. It also
exposes a Component Object Model (COM) interface, Interchange, which enables any
COM–compatible application, such as ASP .NET, the .NET Framework, Microsoft
SharePoint Portal Server or Microsoft Exchange Server, to submit business documents
directly to a channel. Through the freely downloadable BizTalk Adaptor for Web Services
developers can create Web Services that provide synchronous access to BizTalk Server
applications without writing code.
Channels
Once an incoming document is received into the system, it often needs to be transformed to
meet specific business or application formats. Channels can perform a number of operations,
including document transformation and logging. A BizTalk Server channel is set up to
receive incoming documents that conform to a specific document definition, which defines
the ordering of the business data within the document. When the document arrives through a
receive function, a channel can log the whole document or any portion of it to the BizTalk
Document Tracking database for later analysis, or transform the document to conform to the
schema of the target application. BizTalk Messaging Manager is used to manage channels in
a graphical user interface (GUI). In addition, two other BizTalk Server applications can be
used to set up the artifacts used in BizTalk Server channels:
BizTalk Editor, which creates document definitions as an XML representation of business
documents originally defined as flat files, XML, or Electronic Data Interchange (EDI).
BizTalk Mapper, which graphically creates the transformation between two business
documents and saves it in an Extensible Stylesheet Language Transformations (XSLT) map.
Messaging Ports




CORPORATE ONTOLOGY G RID T M                                                                  - 34 -
After documents are received and mapped to the format of the target application, they need
to be delivered either directly to that application or to a business process that manages
delivery to multiple target applications. BizTalk Adapters enable BizTalk Server to integrate
with many standard technologies as well as third-party applications without additional
development work. Messaging ports also push documents to schedules, which manage
business processes that target a number of applications. There is a many-to-one relationship
between channels and ports. Dozens of channels can send documents to a single messaging
port, which is particularly useful when business documents are sent from a variety of
applications to a single target application.
Schedules
BizTalk Server schedules orchestrate the automation of business processes by receiving
documents from a messaging port then calling COM components, other BizTalk Server
messaging channels, or XML Web services (this capability is provided in the BizTalk Server
2002 Toolkit for Microsoft .NET). BizTalk Server schedules are created in a graphical
environment called BizTalk Orchestration Designer, which is based on Microsoft Visio®.
The BizTalk Orchestration Designer consists of two panels on the design surface, the
business analyst panel, and the developer panel. This enables organizations to separate
process from implementation. It also facilitates the rapid creation and alteration of business
processes.
Within a schedule, a business analyst can draw a business process that consists of decisions,
loops, and actions, such as receiving a purchase order, sending a purchase order into an
enterprise resource planning (ERP) system, and so on. In addition, by sending its output to
another BizTalk Server messaging channel a schedule may deliver its document to other
schedules. This enables complex business processes to be segmented into manageable
processes that can be maintained separately.
Tools
BizTalk Server provides a set of sophisticated graphical tools that businesses can use to
build, transform, manage, track, and analyze business documents. The BizTalk Server tools
were designed to simplify the common tasks required to integrate applications and business
systems, and ensure the desired functionality is achieved.
BizTalk Server includes the following graphical tools:

BizTalk Orchestration Designer enables users to visually define and build robust,
distributed business processes.
          BizTalk Editor enables users to define schema for XML, EDI, and flat files.
          BizTalk Mapper enables users to link disparate schemas and define steps for
           successful document transformations.
          BizTalk Messaging Manager is a wizard-based tool that enables users to
           manage the details of business-process transactions.
          BizTalk Server Administration enables administrators to perform common
           administrative tasks such as adding and removing servers.
          BizTalk Document Tracking enables users to track documents as they move
           through various stages of the business process.
          BizTalk SEED Wizard enables rapid partner enablement through the creation
           and use of SEED packages.

     integration with a variety of backend systems.


     Increase productivity with messaging integration
     WebSphere Application Server enables dynamic application interaction through a
     native, high-performance Java Message Service (JMS) provider based on market-
     leading IBM WebSphere MQ technology and support for J2EE 1.3, Enterprise
     JavaBeans (EJB) 2.0. The JMS application programming interface (API) increases
     productivity by defining a common set of messaging concepts and programming
     strategies. JMS further simplifies development by allowing loosely coupled, reliable
     asynchronous interactions among J2EE components and legacy systems capable of
     messaging. EJB 2.0 message beans and containermanaged messaging save valuable
     programming time and skill by allowing requests to be processed without requiring
     code to check for messages when they arrive. And developers can easily incorporate
     new behavior in a J2EE application with existing business events by adding a new
     messagedriven bean to operate on specific business events.


     Maximize ROI with Web services
     WebSphere Application Server extends the J2EE 1.3 programming model by
     providing a comprehensive infrastructure to support the production- ready

      IBM WebSphere MQ version 5.3




CORPORATE ONTOLOGY G RID T M                                                                 - 45 -
      WebSphere MQ messaging products enable application integration by helping
      business applications to exchange information across different platforms, sending
      and receiving data as messages. WebSphere MQ V5.3 is now available for Linux
      for Intel, Linux for zSeries, iSeries and Microsoft Windows XP. They take care of
      network interfaces, assure 'once and once only' delivery of messages, deal with
      communications protocols, dynamically distribute workload across available
      resources, handle recovery after system problems, and help make programs
      portable. So programmers can use their skills to handle key business requirements,
      instead of wrestling with underlying network complexities.


      Enhancements:
               Added security using Secure Sockets Layer (SSL), the Internet standard
                for secure communication.

    TIBCO Hawk™ provides comprehensive system monitoring and management
capabilities.
    Along with the tremendous opportunities of e-business come significant risks. The early
    years of e-commerce have exposed many highly publicized outages that have resulted in
    financial losses, legal liability, and erosion of customer loyalty. Giving customers and
    partners direct access to an enterprise‘s systems increases the need for efficient network
    monitoring and management software that can act, react and even ―pre-act‖ on system
    problems to keep the lines of communications open.
    TIBCO Hawk is a sophisticated tool for monitoring and managing distributed
    applications and systems throughout the enterprise. With Hawk, system administrators
    can monitor application parameters, behavior, and loading activities for all nodes in a
    local or wide-area network and take action when pre-defined conditions occur. In many
    cases, runtime failures or slowdowns can be repaired automatically within seconds of
    their discovery, reducing unscheduled outages and slowdowns of critical business
    systems.

  TIBCO MessageBroker™ performs automated message transformation and business
  object                                                                          mapping.
  Facilitating the exchange of information between two enterprise applications is a lot like
  translating a conversation between two people speaking different languages. In a
  complex environment like an enterprise application network, however, such differences
  must be resolved in a way that enables all participants to take part in the communications
  process. This is a far more difficult challenge–one comparable to that faced by the
  complex network of translators and technologies which facilitate communications at the
  United Nations.
  This is the role TIBCO MessageBroker plays as part of the TIBCO ActiveEnterprise
  family of products. MessageBroker performs rules-based data transformation and
  validation to resolve differences between data models or import/export formats as the
  TIBCO Rendezvous™ messaging software moves data through an application network.
  MessageBroker is the only product that provides rules-based transformation and
  mapping as part of an event-driven system.
  Benefits
              Eases integration of applications and data sources with easy-to-use

  prepare it for use by other systems. By allowing applications to publish content in their
  native formats–just once for all required integration–stability of the information source is
  greatly improved.
  Architecture
  MessageBroker is a distributed system that requires no database or central server.
  Embedded within it are TIBCO Hawk™ AMI implants, which allow automated event-
  driven management of all runtime deployments.




CORPORATE ONTOLOGY G RID T M                                                                     - 65 -
  A graphical user interface combines ease-of-use with powerful transformation semantics
  and extensibility. Once data transformations are defined by a data integration specialist

  TIBCO Substation ES™ enables the real-time and non-invasive integration of
  mainframe applications into end-to-end business processes.
  Many people think of mainframes as old technology, but the majority of corporate data
  still sits on them and they continue to be a very important part of how many enterprises
  operate. Unfortunately, the typical batch-oriented nature of mainframe data storage and
  retrieval makes it hard to include mainframe applications as real-time components of
  dynamic business processes.
  TIBCO Substation ES enables the inclusion of mainframe applications as a seamless part
  of automated business processes by non-invasively enabling them to send and receive
  event-driven messages and information to and from non-mainframe systems.

  Substation ES‘s CICS interface exploits the External CICS Call Interface (EXCI) to
  provide communications between executing CICS transactions and distributed client
  applications. Several methods of invocation are provided, including standard CICS
  invocation methods, Call by Transaction Code, Call by Program Name, and Transfer
  Control (XCTL). In addition, the CICS interface uses the Transient Data Queuing
  facilities of CICS to support ‗Triggers‘, providing a means of publishing events or data
  based on events that occur within the domain of the CICS Region(s).
  IMS Interface
  The IMS Interface includes a full set of Open Transaction Manager Access (OTMA)
  protocols for accessing IMS data sources in the IMS TM environments. (IMS DB/DC
  and IMS DCCTL). TIBCO‘s implementation supports Version 6 and Version 7, and can
  provision the roles of OTMA Client and OTMA Server. The interface supports
  transaction grouping, multi-use Transaction Pipes, and Output routing, and was designed
  to handle very high transaction arrival rates and data transmission requirements.

  TIBCO™ SmartPGM and TIBCO™ SmartPGM FX add reliability and powerful
  content distribution on top of IP multicast.




CORPORATE ONTOLOGY G RID T M                                                                  - 71 -
  The majority of today's network communications use a one-to-one, or unicast,
  transmission model. With unicast, sending the same message to a 1,000 different people
  requires creating 1,000 separate copies of the message and then sending each copy, one-
  by-one, over the network. With IP multicast, a one-to-many transmission model, a single
  message can be sent once and reach all 1,000 people at once. While more efficient than
  unicast, IP multicast typically falls short on one critical attribute: Reliability.
  TIBCO™ SmartPGM
  TIBCO SmartPGM is TIBCO's implementation of the industry standard Pragmatic
  General Multicast (PGM) protocol. SmartPGM adds reliability on top of IP multicast,
  and is ideal for applications that require ordered or unordered, duplicate-free, multicast
  data delivery from multiple sources to multiple receivers.
  TIBCO SmartPGM provides a highly robust, reliable, scalable, and standards-based
  solution for one-to-many and many-to-many content and data delivery over existing
  LAN, WAN, and satellite topologies. TIBCO SmartPGM addresses all reliable multicast
  needs today by providing congestion control and bandwidth management, three different
  types of error correction, and compliance with the multicast standard backed by industry
  giants Cisco and Nortel.
  TIBCO™ SmartPGM FX
  SmartPGM FX is a powerful content distribution product built on top of SmartPGM.
  Optimized for LAN, WAN, and satellite environments, it provides efficient and reliable
  delivery of media-rich content to thousands of simultaneous receivers, regardless of data
  or network type. Because it is built on top of SmartPGM, SmartPGM FX offers a tool set
  that allows a file to be multicast with the same ease and bandwidth usage as a simple
  copy operation.

                                          Comparison

  In the market for transaction- and message-oriented middleware, IBM
  WebSphere MQ is de-facto the standard. It has over 60% of the world market.
  More than 35 platforms, practically all the relevant programming languages and
  all conventional network protocols are supported.




CORPORATE ONTOLOGY G RID T M                                                                   - 72 -
  But IBM WebSphere MQ is even more than just a universal transport medium for
  corporate data. The applications to be linked can run independently of time
  constraints by virtue of asynchronous data transfer and the queuing principle.
  This means that the two applications do not need to be active at the same time.
  This creates flexibility by smoothing peak loads in the network and provides
  security if one of the systems should crash.


  All of the above tools can be used as a middleware in order to connect
  applications within enterprise or between enterprises and this connection can be
  done by using messaging and web services. IBM Websphere can provide
  integration capabilities by supporting not only messaging but also web services.
  Instead of Microsoft Biztalk messaging can be done faster with Websphere. Also
  Biztalk doesn‘t have a universal application connectivity and it doesn‘t support
  Java applications. Also as we can see from the following figure that describes the
  messaging modes, by using Microsoft Biztalk we can have only point to point
  connections and only between Microsoft applications except we are using
  bridges.




     For Tibco product also we can say that it supports Java Message Service
     (JMS) but it lacks strong security issues. Also it hasn‘t a central backbone
     administration and it can‘t support full web services.

     In the following table we can see some of the main capabilities of the above-
     mentioned EAI tools, IBM Websphere, Ms Biztalk and Tibco.

     As we can see from the above table Ms Biztalk can‘t provide high speed
     routing and transformation and it has no web services routing and
     administration. Furthermore Tibco underlying multi-cast technology is a
     limited foundation for backbones, it has no central backbone administration
     and finally it can‘t support web services in backbone.

  Benefits


  Business benefits
  Higher Quality of Business Information – Semantics allows all data assets to be
  integrated, aggregated and transformed automatically, accurately and consistently into
  well defined information according to an agreed-upon unambiguous business
  vocabulary.


  Business Flexibility – Currently, most IT projects fail or miss their objectives. A
  common understanding of data is the only viable basis for deploying new business
  applications, integrating applications, and introducing more flexible process models into
  the enterprise. Data semantics supports business flexibility by providing a coherent
  understanding of the data environment and automatically computing the impact of any
  change.


  Lower IT Costs – Data management creates immediate ROI by promoting the reuse of
  valuable data and the identification and decommissioning of redundant systems. In
  addition, data semantics can be used to automate the generation and maintenance of
  accurate data transformation scripts and queries. The use of consistent data semantics
  ensures the success of other architectural layers supported by IT, including the
  operational stack of packaged applications, enterprise application integration, business
  process integration and web services, and the informational stack of ETL, data
  warehouses, and business intelligence.


  Technical benefits
        One integrated system for metadata, data modelling, semantics with active
         support for data management, data integration, data quality
        Map multiple data assets to one business-oriented information model
        Same system and model caters to relational, XML and legacy data
        Portable to any operating system and any relational database using pure Java
         technology

     content relevant to a specific enterprise Project. The contents of a Coherence Project
     will vary, depending on whether the business requirement is simple, e.g. generating a
     single transformation, or complex, e.g. a substantial data integration Project or
     central enterprise ―thesaurus.‖


     A Coherence Project is the container for all of the main Layers and components used
     within Coherence. The main Layers are the Model Layer (includes Test Instances
     and Queries on the Model) and the External Assets Layer (includes mappings to
     the Model and Transformations).


     The Model Layer contains a rich conceptual Model of the business. This will be the
     reference Model to which data Schemas and other external assets are mapped. It may
     be authored within Coherence or imported partially or fully from other data
     Modeling environments such as Computer Associates ERwin 4.x (4.0 and greater).


     Within the Model Layer, Packages, Classes, Properties, and Business Rules are
     created, edited, and deleted. In addition, the content of ERwin 4.x (4.0 and greater)
     Logical Models and other Coherence Model Layers can be reused by importing them
     into the Model Layer.


     Test Instances are part of the Model Layer. Test Instances are used to demonstrate,
     test and validate concepts in the Model including Business Rules. The user can
     create, edit, view, and validate Test Instances. An XML document containing all of
     the Test Instances within a Project can be generated.


     Queries let users formulate business queries using the business vocabulary of the
     Classes and the Model Properties using an SQL-like structure. Coherence can auto-




CORPORATE ONTOLOGY G RID T M                                                                  - 82 -
     generate an executable SQL query which can be deployed for use on the relevant
     RDBMS whose Schemas have been mapped to the Model.


     Within the External Assets Layer, links can be made to enterprise data Sources
     including logical data Models, RDBMS Schemas, XML Schemas, and COBOL
     Copybooks. A user links to these data Sources from within Coherence and proceeds
     to map the structure of the data Source to the Model,. In this manner, Coherence
     provides rich semantic meaning to data formats – by relating them to a central Model
     with its business vocabulary. Mapping can be done either manually or automatically,
     using the Reverse Engineering feature.


     The Impacted Concepts list is part of a powerful mechanism for viewing the impact
     of changes that have been implemented by the user, thus maintaining consistency in a
     Project. It shows any concepts within the Project that are no longer valid as a result
     of a user‘s actions and allows users to navigate directly from a concept in the list to
     the place in the Project where the concept is located. This navigation helps the
     Modeler quickly locate the consequences of making changes to a Project. It also
     provides a useful ―To Do List‖ of actions that need to be carried out in order to
     account for the change(s).


     Once the user has mapped between external assets and the Model, Data Discovery
     can be used to show which concepts and objects within external assets are linked to
     which concepts in the Model. For example, a user can select a Property in order to
     see which columns in all the RDBMS Schemas within a Project have been mapped to
     it.


     Once mapping has taken place, the user can automatically create, view, and update
     Transformations between pairs of RDBMS Schemas or XML Schemas. The resulting
     SQL or XSLT script can be exported or copied for use in the appropriate application
     or run-time environment (e.g. in an RDBMS or an XML EAI/messaging product).




CORPORATE ONTOLOGY G RID T M                                                                   - 83 -
     In addition to the Layers within a Project, there are two other major cross-Layer
     functions: Concept Attributes and Search.


     Concept Attributes allow the user to add documentation to most Coherence
     concepts within a Project. For instance, a Business Rule can be given a description
     while a Class can have an associated URL, comments on use, owner, and other
     information. The number, content, structure and size of the various fields and tab
     labels are configurable per installation.


     Search allows the user to find concepts across the entire Project using key words or
     phrases. Users receive a list of all concepts within the Project that include the search
     phrase either as part of their name or as part of their Concept Attributes information.


     Projects can be published and exported to a number of different standards. The
     Model Layer and External Assets Layer can also be published as an HTML Web for
     sharing and online collaboration with colleagues across the enterprise. The Model
     Layer can also be generated and exported as XML Schemas and even converted to
     DAML+OIL and RDF/S formats.


     Visually, the Coherence screen is structured according to a hierarchical three-panel
  flow of information:
            o The Project View (top left panel) displays the major Layers and
                components of an open Coherence Project. In the figure below, Model is
                selected in the Project View.
            o The Navigator Panel (bottom left panel below the Project View is used to
                display top-level components of the node currently selected in the Project
                View. For instance, if ―Model‖ is selected in the Project View, then the
                Classes and Packages making up the Model will be displayed in the
                bottom left panel. In the screen shot below, the Class Address is selected
                in the Navigator Panel.




CORPORATE ONTOLOGY G RID T M                                                                    - 84 -
             o The panel on the right-hand side displays detailed information about the
                 concept selected in the Project View/Navigator Panel. This includes items
                 such as Properties of the selected Class or mapping information about a
                 selected RDBMS table. In the figure below, the Property stateCode of
                 Class Address is selected in the right-hand side and its Lookup Table
                 Business Rule called Rule_1 is also selected.




      Features
      The Model Layer within the Coherence GUI
      From within The Model Layer, the user can add, edit, and delete the concepts within
a Coherence Model.
             o When the Model node is selected, the bottom left navigator panel shows
                 the Classes and Packages that making up the Model. This information can
                 be displayed in two ways: the Inheritance Tree Display and the Package




CORPORATE ONTOLOGY G RID T M                                                                 - 85 -
                Display. Each display serves a different purpose and each one displays
                different aspects of the Model. Two toggle buttons allow the user to
                switch between the two displays. These two displays are used throughout
                the application when the user is required to select a Class within a dialog
                box.
            o The Inheritance Tree Display is composed only of Classes. All Classes
                inherit from the Class Being. Datum Classes are grouped at the bottom of
                the tree and have a separate icon. Subclasses are shown as sub-nodes of
                their Superclasses. All Classes appearing under a given node inherit from
                that node (Superclass).
            o A Class can simultaneously inherit from more than one Class. These
                Classes are shown multiple times in the tree under each of their respective
                Superclasses with a special icon showing ―multiple inheritance.‖ In
                addition, the selected Class is displayed in bold text under each of its
                Superclasses.
            o The Package Display shows Packages and their contents (Classes).
                Package and Class names can be edited within the individual dialog boxes
                for each concept. Within each Package, Class names are unique and
                cannot be duplicated. When a Package is highlighted on the left, the
                Package name and any associated user-defined attributes are listed on the
                right-hand side. Packages are not organized in a hierarchy of sub-
                Packages.
            o A combined Quick Find and Find Again field is located at the base of the
                navigator panel. This can be used to search for Classes and Packages in
                the panel above. For instance in Figure 1 if the user were to Type the
                string ―X‖ and then press on the return key or click the Quick Find button,
                the Class Y would be selected and the right-hand side would be updated.
     When a Class is selected in the bottom left-hand side navigator panel within either of
     the two displays, three tabs are displayed on the right-hand side: General, Properties,
     and Subclasses.




CORPORATE ONTOLOGY G RID T M                                                                   - 86 -
     Importing into the Model Layer
     A Coherence Project can import the Model Layer from another Coherence Project.
     The Classes from the imported Model Layer will be placed into a separate
     Package(s).


     An ERwin 4.x (4.0 and greater) Logical Model (exported as an .XML file) can also
     be imported into a Coherence Project. Concepts in ERwin are converted into Classes
     and Properties.




     Test Instances
     At any point in the authoring of an ontology Model, a user may define Test Instances
     of any of the Classes in the Model. Test Instances allow the user to select a Class and
     to insert data into specific instances of this Class in accordance to the Class‘
     Properties. This feature gives feedback on how real data will look and behave and
     how the structure of the Model and the Business Rules impact on real data. Test
     Instances also help uncover flaws in a Model.


     Conceptual Business Query Builder
     Users can quickly generate complex SQL queries that can be copied and deployed
     offline against underlying relational data Sources. Coherence‘s Conceptual Business
     Query Builder provides key business benefits with this feature.
            Automated Querying
            o Allows users to query using agreed terminology without having to know
                the specific terminology of the underlying data Source, thereby making
                queries easy to formulate and without unambiguous meaning
            o Saves time by eliminating the need for users to hand-code SQL queries.


     External Assets Layer




CORPORATE ONTOLOGY G RID T M                                                                   - 87 -
       Concepts & Processes in Mapping
       The External Assets Layer provides the user with an opportunity to introduce
       enterprise metadata into a Coherence Project and give it meaning by mapping
       concepts within them to concepts in the Model. Coherence supports the following
       external assets: RDBMS and XML Schemas, ERwin Logical Models and COBOL
       Copybooks.


       Key strengths of Coherence are derived from the results of mapping enterprise
       metadata in the form of external assets to the conceptual business Model. Mappings
       defined between external assets and the Model are used by Coherence to generate
       transformations and queries.


       Below is a table summarizing the different concepts for each external data asset.

  RDBMS Schema             Tables                 Columns              Foreign Keys
  XML Schema               ComplexTypes           Elements of          Elements of
                                                  SimpleType, and      ComplexType
                                                  Attributes
  ERwin Logical Model      Entities               Attributes           Relationships
  COBOL Copybook           Group Items            Elementary Items     Subgroups

       Mapping RDBMS Schemas
       RDBMS Schemas need to be linked to via their .SML files created by the Coherence
       Schema Converter. Once the link has been created, the Schema is shown in the
       Project View and its tables are shown in the navigator pane below. Selecting a table
       brings up information on the table, displayed in three tabs: Mapping, Foreign Keys,
       and Table Info.


       Mapping XML Schemas
       XML Schema mapping is similar in structure to RDBMS mapping,.


       Mapping ERwin Logical Models
       ERwin 4.x (4.0 and greater) Logical Models saved as .XML files can be linked into a
Coherence Project.




CORPORATE ONTOLOGY G RID T M                                                                  - 88 -
     Mapping Groups are defined on Entities while Attributes, Parent Relationships, and
     ERwin Groups are mapped to Properties.


     Mapping COBOL Copybooks
     While Copybooks can be used for numerous purposes, Coherence currently supports
     those Copybooks belonging in the Data Division of a COBOL program (i.e.
     Copybooks that can be read in to the Data Division using the COBOL Copy
     command).


     Transformations
     Transformations can only be viewed by a Coherence user after one or more
     transformations have been generated. Following generation, a transformation is
     displayed twice in the Project View (under the relevant Source and Target Schemas).
     Transformations need to be updated by the user following relevant changes in the
     Model or Mapping Layers. The Update Transformation button updates all the table
     transformations for the transformation between the Source and Target Schema.
                o SQL transformations
                o XSLT transformations


     Data Discovery
     Data Discovery allows the user to see the type and location of data in the external
     assets according to business concepts represented in the Model. Data Discovery is
     available at the Class and Property levels.


     The business benefits of this feature are significant:
            o Data duplication and overlap can quickly be seen
            o The location of data can be identified precisely
            o Interlinking and cross-referencing between data Sources from one Schema
                to another (using implicit links through the ontology Model) can be seen.
            o Coherence can serves as a central point from which all mappings can be
                quantified, attributes compared, and Model concepts contrasted.




CORPORATE ONTOLOGY G RID T M                                                                - 89 -
             o Security and privacy policies can be assessed e.g. if access to a certain
                business concept needs to be restricted – this feature can identify all the
                external assets which must be restricted to make the policy work.


     Publishing & Exporting Work Around the Enterprise
            Publishing a Project in HTML Locally
             The business benefits of this feature are significant. Publishing a Model in
             HTML format allows the user to:
                    o collaborate on or share a Model with other contributors who may
                       not have Coherence installed;
                    o have a lighter version of a Conceptual Model for quick reference
                       at alternate locations;
                    o explain complex relationships in a familiar interface (a browser) to
                       non-technical users;
                    o use the HTML file for posting on a website, an Intranet, or an
                       Extranet.


          Publishing a Project in HTML to Web Server
          Deploying SQL Transformations
          Generating XML Schemas
          Exporting a Project in DAML+OIL
          Exporting the Model, Mappings, Schemas & Test Instances in RDF


    UNICORN 2.5 studies and evaluation.
    UNICORN system suggests using of a semantic approach for enterprise data
    management. It assumes creating of a Semantic Information Model that should contain
    a vocabulary of notions and business rules (conceptual model) and catalog of data
    assets (metadata). Metadata describes physical structure of the information stored in
    different data sources inside enterprise (RDMS, XML Schemas, flat files, etc).
    Therefore metadata catalog reflects more physical model of enterprise data. Semantic
    model binds conceptual and physical models by means of mapping metadata elements




CORPORATE ONTOLOGY G RID T M                                                                  - 90 -
    on conceptual notions. Such approach allows facilitating of automated support for data
    management, data integration and data quality.
    UNICORN workbench version 2.5 enables creation and support of Semantic
    Information Model for any enterprises including virtual organizations. As it was
    mentioned before it also support integrity checking, data discovering and
    transformation, publishing, sharing and synchronization.
    The tool was tested on real projects with the aim to evaluate its functionality, usability
    and effectiveness in working with large amount of data. Also we reckon with security
    and robustness issues of the Unicorn system.
    We follow the procedure that described in the online tutorial for the system. It includes
    the next steps:
     1. Creating the catalog of enterprise sources
     2. Building the information model
     3. Mapping sources to the model
     4. Employing active capabilities
     5. Maintaining changes.
     6. Publishing and sharing


    1.   Creating the catalog of enterprise sources


    The catalog of enterprise sources contains metadata assets that can be imported from
    the various sources. Built-in capabilities include import from Oracle and MS SQL
    server schemas, COBOL Copybooks and Erwin logical schemas. Other asset formats
    could be imported via Unicorn‘s API.
    We try all import schemas except COBOL. Some problems were detected with Erwin
    4.0 XML files. When system could not define attribute types correctly they had a
    Datum type and therefore could not be easily mapped to the concepts of information
    model. In some cases primary keys of integer types receive realNumber type after asset
    loading.




CORPORATE ONTOLOGY G RID T M                                                                     - 91 -
    We also try to use an MS Access database adapter to receive Access db schema. It
    works well with a sample access database but on one test computer some sample
    projects ceased loading from project repository when msAccess adapter was installed.


    However, in general, asset loading wizard is very transparent to user and allows
    reverse engineering of asset to informational model immediately after loading.


    2.       Building the information model
    There are three ways to create the Information Model in Unicorn:
         1.     By importing an existing Model.
         2.     By reverse engineering an asset.
         3.     By creating a Model from scratch.


    Importing can be made from existing Unicorn model (from repository or
    archive) or from Erwin logical model. Importing feature works well in all
    cases.


    When an asset is reverse engineered, the following takes place:
             Unicorn adds an Instance Group for each composite
             A new Class is created for each composite that contains new Properties
              for each of the atoms. Each of these Properties is of a Type that matches
              the atom's asset.
             Mappings are created between the Schema atoms and the newly created
              Properties


    But after importing or reverse engineering of asset you should pay a great
    attention on recommendation that are given in Unicorn online help. They are:


             The existing Model should be normalized
              The more normalized a central Model is, the better. Even heavily




CORPORATE ONTOLOGY G RID T M                                                               - 92 -
           denormalized systems can be mapped to a normalized Model. It can be
           difficult to map anything to a denormalized Model.
          The existing Model should be extensible
           The Model should be open to extension – it should be clear where
           organization specific additions and alterations will fit within the Model.
           When extending a Model, the Modeler must be familiar with the
           structure of the Model they are extending.
          The existing Model should be clean
           The Model should not have features that are not applicable to the
           organization‘s business. Having extra Classes is more acceptable than
           extra Properties. Extra Classes indicate a wider scope than may be
           appropriate, but the area of overlap can still be used productively. Extra
           Properties indicates an over specificity. The Modeler will likely have to
           carve away the unneeded Properties to use the Model.
          The existing Model should be comprehensible
           The Model should be easy to understand without too much explanation.
           To this end, it should also be well documented.


    These are the very significant requirements, especially, the first one. But it seems
    rather unclear what is the meaning of ―normalized model‖ in that content. A
    normalization to third normal form looks like a very expensive process, if we are
    speaking about enterprise information, and it requires a good skill from IT specialists.
    On the other hand semantic approach allow using simple concept or notions and
    business rules to describe complex relations between informational entities without
    strong requirements to normalization.


    When the new model is created manually you can use packages, classes, properties and
    business rules for describing basic concepts and functionality. The main steps in model
    creation are described in detail in ―Unicorn Modeling Guide‖ and partially in the
    online help system. However, many complex issues of modeling (describing of many-




CORPORATE ONTOLOGY G RID T M                                                                   - 93 -
    to-many relationship, inversion of properties, work with functions) are well illustrated.
    A well supporting help system is also a substantial positiveness of Unicorn system.


    Semantic model of Unicorn is tangible and convenient. It uses classes as central
    element for information modeling.
    After the information model has been created, user can check it with real data with use
    of Test Instance regime. The last one seems to be very handy for classes with simple
    properties and also for classes with complex properties - containers (Set, Sequence,
    List, Bag types).


    3.   Mapping source to the informational model


    Mapping is one of the most complex task. The user must define semantic relationship
    between different kind of sources with classes of informational model. You have to
    keep in mind very many restrictions and rules when mapping from RDBMS schemas,
    something more when working with Erwin models and XML schemas. Unicorn help
    gives some advices about this process, and it gives users the possibility to become a
    skilled in the mapping procedure.


    Unicorn proposes map a table         to class, column and relations to properties in
    informational model. Unicorn suggests mapping supporting tables first, the tables on
    the "one" side of Many-to-One relationships. This way you can easily map complex
    tables that have foreign keys to the supporting tables. If you want to map many-to-
    many related tables to the informational model, you have to use a separate instance
    groups with joins, conditions or implicit foreign keys to make this mapping. So from
    our point of view Unicorn has reach possibilities for mapping, and it is a helpful tool
    for someone who wants to map sources to information models.


    4.   Employing active capabilities




CORPORATE ONTOLOGY G RID T M                                                                    - 94 -
    When an Information Model have been established, and mapped, you can generate the
    services you require, such as Data Discovery, Transformation Generation and Schema
    Generation.


    Data Discovery is a very useful for searching and analyzing of data redundancies and
    partial overlap between data sources. It displays the type and location of data in
    external assets, according to business concepts (at both the Class and Property levels)
    represented in the Model. Results can either be displayed by external asset type or
    irrespective of asset type.


    The business benefits of the Data Discovery feature are significant:
          The location of data can be identified precisely
          The Unicorn system can serve as a central point from which all
           mappings can be quantified, attributes compared, and Model concepts
           contrasted
          Data duplication and overlap can quickly be brought to attention
          Interlinking and cross-referencing between data sources, from one
           Schema to another (using implicit links through the Information
           Model), can be seen


    Other suggested service for inspecting data is a Find. Find is carried out on concept
    names and on concept descriptors and allows finding information on particular
    subjects within the Model and external assets within a Project. Results are ordered by
    concept Type.


    Data transformation capabilities enables generation of schema transformation between
    RDBMS (Oracle 8i and MS SQL 7 and 2000) and between two XML Schemas.
    Transformation between ERwin logical models (XML files) and other RDBMS is not
    supported.

    For transformations between RDBMS Schemas, the resulting SQL script can be
    viewed either for the whole transformation or per Target table. For transformation
    between XML files, the transformation plan resulting is formed in XSLT file.
    Transformation plan for both type of transformations can be viewed in Unicorn or can
    be   exported    to   XML      file   and   viewed    with    use   of   separate   utility
    TransformationPlanner as Excel file.


    5.   Maintaining changes


    Unicorn has a powerful mechanism for checking integrity of the project and
    synchronization with external assets. User can change or delete a concept and the
    system reflects all entities that will be impacted before making any real changes. Undo
    operation is also included. In any time you can check the integrity of your model with
    use of Integrity checker function that fix all inconsistencies.


    Unicorn takes a great care of external asset and transformation synchronization. It
    applies to RDBMS assets – when DB schema have been changed, Unicorn can update
    the asset and corresponding transformation schemas.


    6.   Publishing and share


    Unicorn has abilities export information model and project metadata into HTML and
    to maschine-readable formats as DAML+OIL or RDF by using external utilities
    supplied by Unicorn team.


    Also you can generate Information model as XML schema or in graph represenation.


    7.   Security


    Unicorn allows working in multi-user environment and should take a great care about
    security. It is very important to have an opportunity to secure not only informational

    model packages and classes but external assets schemas also. Personal system it offers
    the opportunity for security protection as it declared in online help system..
    Administrator also has the ability to set permission from a level of project to a level of
    class for an informational model and to a level of table for external asset.


    8.   Robustness


    We explore Unicorn system on two computers with 128 Mb RAM and Windows 2000
    installed. We have discovered that Workbench needs more than 100 Mb memory when
    launching and then it requires about 20 Mb for each project. So the application
    requires a lot of system resources and has good robustness.




                                       SUMMARY


    Unicorn system is a standalone software system that provides a complex management
    of enterprise data and support of Central Information Model. It combines rich abilities
    in information modeling (Protégé) with power tools of metadata analyzing and
    generation (ERWin, SilverRun, MSVisio). It enriches these with semantic relations
    between concepts of information model and entities of metadata structure allowing the
    new approach to enterprise data management - Semantic Information Management.


    Unicorn system could be integrated with EAI products such as IBM Websphere MQ,
    TIBCO, MS BizTalk. These products provide an important platform for integrating
    applications and especially for facilitating messaging and workflow. However, these
    can be deployed and maintained far more cheaply and flexibly if their translation
    scripts are auto-generated rather than manually coded.
