“ Model-Driven Architecture (MDA) is a software design approach that its sponsor, the Object Management Group (OMG)[1], officially launched in 2001. MDA supports model-driven engineering of software systems.
Model driven architecture is a model-driven engineering (MDE) approach that uses three types of models:
CIM - computation independent model that describes how a system should be behave in terms of a language that is appropriate for a user (e.g. an educational designer, a business analyst, etc.)
PIM - platform independent model that describes a CIM in computational terms, i.e. a language that makes sense to a given class of computer persons but is independent from specific computer technology
PSM - platform specific model that links PIM specification with specific information about a specific platform and it should be executable.
