Overview
The Model-Driven Architecture approach defines system functionality using a platform-independent model (PIM) using an appropriate domain-specific language (DSL).
Then, given a platform model corresponding to CORBA, .NET, the Web, etc., the PIM is translated to one or more platform-specific models (PSMs) that computers can run. This requires mappings and transformations and should be modeled too.
The PSM may use different DSLs, or a General Purpose Language (GPL) like Java, C#, PHP, Python, etc.. Automated tools generally perform this translation.
The OMG organization provides rough specifications rather than implementations, often as answers to Requests for Proposals (RFPs). Implementations come from private companies or open source groups.
MDA principles can also apply to other areas such as business process modeling (BPM) where the PIM is translated to either automated or manual processes.
