Why use the model driven architecture to design and build distributed applications?

Abstract

OMG's model driven architecture/spl reg/ (MDA/spl reg/) unifies and simplifies modeling, design, implementation, and integration of applications - including large and complex ones - by defining software fundamentally at the model level, expressed in OMG's standard Unified Modeling Language/spl reg/ (UML/spl reg/). An MDA-based development goes through three steps - two producing models, one producing code - and typically iterates through these several times.
