November 2004 Cutter Benchmark Review: MDA and JAVA
The Object Management Group's Model Driven Architecture (MDA) is slowly but surely gathering momentum. It's gaining adherents for several reasons, but probably the most important is that every large company faces serious enterprise application integration (EAI) problems, and MDA offers a solution. In essence, the solution lies in making various metamodels conform to a common meta-metamodel (the Meta-Object Facility, or MOF) so that specific metamodels can easily arrange to exchange data. Each specific metamodel defines a mapping to MOF. Then, to exchange data, one moves a specific diagram or model via one transformation into MOF and, via a second transformation, into the metamodel of the target system. Companies such as IBM are defining MDA mappings so that in the future customers will find it much easier to move from one IBM product or application to another.
