Model driven architecture : applying MDA to enterprise computing

Model Driven Architecture (MDA) is a new methodologyf rom OMG that uses modeling languages like UML along with programming languages like Java to build software architectures PriceWatersCoopers′ prestigious Technology Center just predicted that MDA will be one of the most important methodologies in the next two years Written by the lead architect of the specification who provides inside information on how MDA has worked in the real world Describes MDA in detail and demonstrates how it can work with existing methodologies and technologies such as UML,MOF, CWM, and Web services
