Model Driven Development

• SE-690 Research Project
• Initial Presentation
• Anteneh Kefale
• March 2004

What is Model Driven Development

• Model Driven Development (MDD) is a new paradigm
  for developing enterprise software applications.
• It utilizes the Model Driven Architecture (MDA)
  approach recently released by the Object
  Management Group (OMG).
• Its believed to give a big productivity gains
  over traditional code-centric software
  development.

What is MDA?

• A development paradigm that aims to insulate
  business and application logic from technology
  evolution.
• Move software development to a higher level of
  abstraction
• Helps build code quickly in a well-architected,
  consistent and maintainable fashion

4
Development Process with MDA

• Secure business requirements for an application.
• Develop UML diagrams for the domain model
  independent of any particular technology (J2EE,
  Microsoft .NET, CORBA)
• This UML model is called Platform Independent
  Model (PIM)
• Its the description of the application in the
  form of metadata

5
Next step

• Build a model for the application specific to a
  particular technology
• (J2EE, .NET,CORBA, etc.)
• This is the Platform Specific Model (PSM)
• Can be built manually or can be generated using
  an MDA tool

6
Last step

• Generate the application code based on the UML
  model, using an MDA tool
• In case of J2EE Servlets, JSPs, EJBs
• Finally hand-tune code

Suggested Benefits of MDA

• Faster development time
• Architectural advantages
• Improved code consistency and maintainability
• Increased portability across middleware vendors

9
MDA Benefits

• Full support for future architecture across the
  application lifecycle
• Reduced cost from beginning to end
• Reuse of application model, code
• Technology-independent representation of the
  business
• Stable model-based approach maximizes ROI

OMG MDA Adoption Status

• More and more groups are thriving on MDA approach
• - Electronic Commerce
• - Financial Services
• - Health Care
• - Life Sciences Research
• - Manufacturing
• - Space and Ground Systems
• - Telecommunications

11
My Goals

• Study some of the freely available MDA tools
• Analyze how well these tools increase
  productivity compared to code-centric development
• Compare some of the tools and determine their
  strength and weakness

12
My Goals

• Project will concentrate on J2EE
• Develop an application using J2EE
• Enterprise Java Beans (EJBs)

13
Deliverables

• Small applications to show the feasibility of
  this new technology and its suggested benefits
• Estimates of productivity gains

14
Work Plan

• Background Research January 2004 March 2004
• First presention March 5, 2004
• In depth research and analysis of MDA tools
  March 2004 April 2004
• Develop demonstration programs using MDA tools
  April-May 2004
• Complete research and perform final presentation
  May 2004
