The idea is that architecture can be easily adapted to different situations, whether they be legacy systems, different languages or have not found the platform. MDA is therefore, a significant evolution of object-oriented approach to systems development. Advanced System Design with Java, UML and MDA describes the factors involved in designing and building large systems, illustrating the design process through a series of examples, including a Scrabble player, a jukebox using web streaming, security systems, and others. The book then moves on to discuss the overall system design, design a system that includes Internet, web services, Flash, XML, XSLT, SOAP, Servlets, Javascript and JSP. At the end of this book, the concepts and terminology Model Driven Architecture are discussed.
