Thema: Architecture Stratification
Abstract:
The OMG's new MDA (model driven architecture) approach promises a large productivity gain by making models the primary software artifact, thus insulating software designs against frequent changes in realization technologies. However, the proposed separation into PIM (platform independent model) and PSM (platform specific model) is not sufficient. Architecture Stratification is proposed as a multi-stage (as opposed to two-stage) transformation process, enabling all aspects (not just platform dependencies) of a system to be introduced one at a time. Each such stage (stratum) represents a level of abstraction that is of some value for a particular stakeholder/developer. The approach takes the age old idea of stepwise refinement but interprets it in a spatial rather than temporal manner. It is compatible with and complements technologies such as separation of concerns, frameworks, and design patterns.
