Overview
 This language compares to JavaServer Pages (JSP),
  ASP.NET, or PHP, and resembles HTML in syntax.
 The most distinguishing feature is its associated
  scripting language, ColdFusion Markup Language
  (CFML).
 ColdFusion supports programming languages other
  than CFML, such as server-side Action script and
  embedded scripts that can be written in a JavaScript-
  like language, known as CFScript.
Overview
 ColdFusion is most often used for data-driven web
  sites or intranets, but can also be used to generate
  remote services such as SOAP web services or Flash
  remoting.
 It is well suited as the server-side technology to the
  client-side Flex.
 ColdFusion can also handle asynchronous events such
  as Short Message Service (SMS) and instant messaging
  via its gateway interface.
Overview
 What is ColdFusion capable of?
   Query a database
   Allow users to upload files
   Create/read files on the server (for example, the files that your users
    upload)
   Have a "member's area" (i.e. via a login page)
   Have a shopping cart
   Present a customized experience (for example, based on users'
    browsing history)
   Create a "member's area" (i.e. via a login page)
   Send emails (for example, newsletters to a mailing list)
   Schedule tasks to run automatically (for example, your email
    newsletters)
   FTP files to/from another server
   Publish web services
Overview (Disclaimer)
 Down sides to using ColdFusion
   Expensive.
       Costs $1,299 full version, $649 upgrade version.
   Not as popular as PHP, ASP.NET, or JSP.
       Most companies use one of these 3 technologies.
       Limited job search.
   Primarily used in corporate environment.
   Not all web hosting companies support it.
   Those that do (www.godaddy.com) charge extra for using
    it ($1.99 / month).
Main Features
 Client and server cache management.
 Client-side code generation, especially for form widgets (GUI
    that displays an information arrangement changeable by the
    user, such as a window or text box) and validation.
   Conversion from HTML to PDF and FlashPaper (virtual printer ;
    all files printed from FlashPaper become Flash or PDF files).
   Data retrieval from common enterprise systems such as Active
    Directory, POP, HTTP, FTP, Microsoft Exchange Server.
   Platform-independent database querying via Open Database
    Connectivity (ODBC) or Java Database Connectivity (JDBC).
   XML parsing, querying, and validation.
Other Programming Languages
 ColdFusion and Java
    ColdFusion can be deployed to servlet containers such as
     Apache Tomcat and Mortbay Jetty.
    ColdFusion is a Java EE application
        Enterprise Edition: builds on the solid foundation of Java Platform,
         Standard Edition (Java SE) and is the industry standard for
         implementing enterprise-class service-oriented architecture (SOA)
         and next-generation web applications.
    Its code can be mixed with Java classes to create a variety of
     applications and utilize existing Java libraries.
    It has access to all underlying Java classes, supports JSP
     custom tag libraries, and can access JSP functions after
     retrieving the JSP page context.
Other Programming Languages
 ColdFusion and .NET
    ColdFusion 8 natively supports .NET within the CFML syntax.
    Developers can simply call any .NET assembly (partially
     compiled code library for use in deployment, versioning and
     security) without needing to recompile or alter the assemblies
     in any way.
    Data types are automatically translated between ColdFusion
     and .NET.
    Offers ability to access .NET assemblies remotely through
     proxy which allows users to leverage .NET without having to
     be installed on a Windows operating system.
Installation
 Before installing, it is a good idea to shut down your
  firewall. Some firewalls may cause installation errors.
 Step 1: After confirming the language on first screen,
  the ColdFusion installation process begins.
Installation
 Step 2: Confirm the license agreement:
Installation
 Step 3: Select the installation type.
    If you have a purchased copy, then enter the serial
     number at this screen.
    In most cases, selecting “Developer Edition” is fine.
Installation
 Step 4: Installer Configuration
    The first option (“Server Configuration”) is the most
     common option.
Installation
 Step 5: Subcomponent Installation
    Select the subcomponents you want to install. By
     default, all subcomponents are selected.
Installation
 Step 6: Select Installation Directory
    Select the directory you would like to install into. It is
     recommended to leave this as default.
Installation
 Step 7: License Agreement
    This screen only appears if you previously selected
     Adobe LifeCycle Data Services ES (at step 5):
Installation
 Step 8: Adobe LifeCycle Data Services ES Installation
    If you have a serial number for Adobe LifeCycle Data
     Services ES, enter it here. Otherwise leave it blank:
Installation
 Step 9:Previous ColdFusion Installation Detected
    If you do, you can choose to have both versions co-exist
     on your computer, or to overwrite the previous version.
Installation
 Step 10: Configure Web Servers/Websites
    If you run your own web server (such as IIS or Apache),
     this screen allows you to select which websites should be
     configured to use ColdFusion. Click on “All IIS websites”:
Installation
 Step 11: Choose ColdFusion Administrator Location
    This screen lets you choose where to put the files for the
     ColdFusion Administrator. The CF Administrator is
     usually accessed at http://localhost/cfide/administrator
Installation
 Step 12: Administrator Password
    You are required to enter a password for accessing the
     CF Administrator.
Installation
 Step 13: Enable RDS
    As a general rule, disable RDS on production servers.
     Only enable RDS if you need to access the server
     remotely for development purposes. In this
     demonstration, it is important to ENABLE RDS:
Installation
 Pre-Installation Summary
    Review your settings. If all is correct, click “Install”:
Installation
 Step 15:
    Once it has been installed, a notification window tells
     you installation was completed successfully. If not, you
     will be notified of any errors that occurred during
     installation:
Tag Syntax
 ColdFusion Syntax refers to a set of rules that
  determine how the ColdFusion application will be
  written and interpreted by the CF Server.
 These rules are referred to as the ColdFusion Markup
  Language (CFML).
 CFML consists of a number of tags.
 Similar to HTML, these usually consist of an opening
  tag and a closing tag, and are surrounded by greater
  than (>) and less than (<) symbols .
Tag Syntax
 ColdFusion tags use the following format:
    <tagname attribute=“value”>
        Code/text that is affected by the surrounding tags.
    </tagname>

    Code Example:
     <cfoutput query=“myQuery”>
            #firstname#<br />
     </cfoutput>
