Data Management

Data management comprises all the disciplines related
to managing data as a valuable resource.

                                       Database

                                         Files
                                       Records

                                        Fields

                                         bytes

                                          bits

Data are organized in a hierarchy
  Traditional approach to data management

Maintaining separate data files for each application.
For example, an employee file would be maintained
for payroll purposes


One or more data files are created for each application.

Duplicated files results in data redundancy.

The problem with data redundancy is the possibility that
updates are accomplished in one file but not in another,
resulting in a lack of data integrity.
A critical success factor: IT applications cannot be
done without using data.

The Difficulties of managing Data:

The amount of data increases exponentially with time

Data are scattered throughout organization and are
collected by many individuals using several methods and
devices.

An ever- increasing amount of external data needs to be
considered in making organizational decisions.

Data security, quality, and integrity are critical, yet are
easily jeopardized.
Data Sources

Internal Data Sources: data about people, products,
services, and processes.

Personal Data: IS users or other corporate employees may
document their own expertise by creating personal data.

External Data Sources: Data from commercial databases,
sensors, satellites, etc.


Areas that are considered within data management

To overcome the potential problems with traditional data
management, the database approach was developed.
Data Warehousing

A data warehouse (DW) is a subject-oriented, integrated,
time-variant and non-volatile collection of data intended to
support management decision making.

Data Mining

Data mining is the process of extracting valid, previously
unknown, comprehensible, and actionable information
from large databases and using it to make crucial
business decisions.
Data Modelling

Data modelling is a way of creating a structure for data
that one intends to collect.
 Data Movement

 Data movement is the ability to move data from one place
 to another.

 Database Administration

 To manage the database environment.


  Knowledge Management

A simple collection of data does not represent information,
and equally, a simple collection of information cannot be
considered as knowledge.
Knowledge management is first and foremost a
management discipline that treats intellectual capital as a
managed asset.

It also refers to an organization’s strategic efforts to gain a
competitive advantage by capturing and using the
intellectual assets held by its employees and customers.

Capturing and flowing of an organization's data,
information, and knowledge is delivered to individuals and
groups engaged in accomplishing specific tasks.

The primary goal of knowledge management is to deliver
the intellectual capacity of the firm to the knowledge
workers who make the day-to-day decisions that in
aggregate determine the success or failure of a business.
Knowledge management is not about creating a central
database.

Knowledge management is about embracing a diversity of
knowledge sources

Databases
Web sites
Employees
Partners

and support that knowledge where it resides, while
capturing its context and giving it greater meaning through
its relation to other information in the company.
Approaches to knowledge management

knowledge creation

knowledge storage and retrieval

knowledge transfer

knowledge application

Transfer: Two parties must cooperate in order for
knowledge transfer to occur. The knowledge creator (or
possessor) must be willing and able to share the
knowledge. The knowledge consumer must be willing to
apply the shared knowledge.
Knowledge Management (KM) Conceptual Model
Importance of Knowledge Management

o   Identify information needs
o   Access, store, and retrieve data and information
o   Use search engines and other tools to retrieve information
o   Accumulate knowledge and share with others
o   Harvest knowledge to make better decisions
o   Improving organizational performance
o   Sharing of information and best practices
o   Strategic – Focus on Excellence and Achieving Vision
o   Operational – Focus on Accomplishing the Mission
o   Tactical – Focus on Effective and Efficient Management of
    Processes
Knowledge Management Is Not:

•   Data Processing
•   Information Management
•   Information Technology
•   E-Learning
•   E-Business

Knowledge Management Is:

• A Management Discipline
• An Enabler for Decision Making, Problem Solving, and
  Continuous Improvement
• The Key to Organizational Management and
  Performance Excellence
Knowledge Management is the totality of activities that an
organization brings to bear to provide:

The right data / information / knowledge:

– to the right persons
– at the right time and place
– in the right quantity and quality

For the purpose of enhancing:

– decision making and
– problem solving
In order to continuously improve:

– business processes,
– products and services,
– customer satisfaction and loyalty,
– employee satisfaction and engagement, and
– overall organizational performance

With the ultimate desired outcome of:

– serving the public, and
– creating or adding value to society overall
• KM deals with knowledge from external as well as
internal sources including documents and databases

• KM systems embed and store knowledge in business
processes, products and services

• KM systems’ objective is to promote growth, transfer and
share of knowledge within the organization

• KM systems aim to assess on a regular basis the
knowledge assets of an organization and its impact.
