Problem Statement

⇨ Software Development is error prone, repetitive, expensive, slow and unagile.

⇨ End product is usually different from whatuser wanted.(Lost in translation)⇨ Developers lack sense of creative

gratification as most of the time they are just boilerplating / repeating themselves.

⇨ Documentation and actual code soon fall out of sync

A New Paradigm

⇨ Assembly lines revolutionized manufacturing by bringing an order of magnitude productivity and quality gain.

⇨ Software Development needs a similar radical change

Patterns in S/W Engineering

Repetitive, pattern bound aspects of data driven application development such as

persistence,validations,facades for exposing APIs (such as web services),workflows,navigation

render themselves well to MDA style rapid developme

PIM and PSM

⇨ Ideally UML/Text/XSD model that captures the problem space should be free of any platform specific artifacts.

⇨ PSM or platform specific model is what is generated from the PIM.

Transformation/Generation

Making best practices easy practices

⇨ Automatic generation of unit tests ⇨ Small maintainable code⇨ Design by constraint enforcement⇨ Archetypes support best practices

compliant project structure
