On the Transition from Computation Independent to Platform Independent Models

The Model Driven Architecture (MDA) describes software development based on models on different levels of abstraction. The development process is outlined as a sequence of model transformations which add specific details to the software models with each subsequent step. The OMG MDA guide refers to the computation independent model (CIM) as the highest level of abstraction. However this model type is disregarded by most MDA methodologies and tools, which start their transformation process on the level of platform independent software models (PIM). This paper investigates the role and nature of the CIM, especially focussing on development processes for management information systems. Therefore, existing transformational approaches for the transition from models as real world perceptions to software designs are evaluated. Finally the transformational view on software development is extended by decision theory aspects during the design task, which significantly influence the feasibility of design process automation.
