About the White Paper:
Since the bloom of networked computing during the last half of the 1990s, the IT industry has seen a parade of new middleware platforms come and stay. (Support costs would be lower if they would come and go, but this never happens.) In spite of claims by advocates that each one was so superior to its predecessors that it would take over the entire middleware space, each has only been able to establish itself in the restricted segment where it offered an advantage. As a result, today's enterprise IT department may have to support applications using CORBA (still the only vendor- and operating-system independent, standardized middleware), COM/DCOM/ActiveX, Java/RMI, EJB, XML/SOAP, and other middleware platforms. To these, we are now adding C#/.Net and the main topic of this article, Web Services (WS).
To the enterprise supporting this complex infrastructure, there is pain at two levels: First, building distributed applications is hard, and second, integrating the multiple applications that work together to run a business is even harder. In this white paper, we'll show how OMG's Model Driven Architecture (MDA) reduces the pain at both levels.
