What is the software factory?
4
Demo Examples
5
A software factory is a software product line
that configures extensible tools, processes, and
content using a software factory template based
on a software factory schema to automate the
development and maintenance of variants of an
archetypical product by adapting, assembling, and
configuring framework-based components.

Benefits

• Integrated with Visual Studio 2005
• Skills do not really matter
• Using CAB WinFx has been made easy
• Enforced consistency
• Ability to extend the GAT package
• Risks are reduced
• Ensure compliance with the open standards (WS-,
  WC3)

Do more at less time

Any Drawbacks???

• Once code is created, its detached from the code
  generation engine

You better try it yourself to find out

Windows Communication Foundation (WCF)

• Part of .NET framework 3.0
• Sub system that simplifies implementing and
  managing web services with contract-based
  messaging

Contracts

• Service Contract
• Data Contract
• Fault Contract

Available GAT Packages

• WCF Service Factory Guidance for WCF-based
  applications
• Web Service Factory (ASMX) Guidance for
  WSE-based application
• Smart Client Software Factory Guidance for
  Smart Clients using Composite UI Application
  Block (CAB)
• Mobile Client Software Factory Guidance for
  Mobile Clients using CAB
• Guidance Explorer
• to find and use relevant patterns practices

Conclusion
Off The Record Intergen has led a major project
for ESR to build a SOA-based system using WCF and
the Service Factory, which has been successfully
delivered before the deadline to UAT and
production.
