An MDA Method for Automatic Transformation of Models from CIM to PIM

The Model Driven Architecture (MDA) approach introduces a clear separation of the business logic from the implementation logic that's less stable. It uses the models that are more perennial than codes. It puts the models at the centre of the development of software and of the information systems. The MDA approach consists at, firstly, developing the CIM Model, secondly, obtaining the PIM model from the CIM, and finally generating the PSM model from the PIM which facilitates the generation of code for a chosen technical platform. In the literature, several works have summarized the MDA approach to the passage from PIM to PSM then from the PSM to code. Yet, very little work has contributed in the axis of the CIM to PIM transformation, and their approaches generally propose a CIM model which does not cover the different specifications of the Object Management Group (OMG) and/or the CIM to PIM transformation that they define is in the most cases manual or semi-automatic. Thus, our proposal aims at providing a solution to the problem of constructing CIM and its automatic transformation at the PIM using the QVT transformation rules. The approach proposes to represent CIM by two models: The business process model reflecting both the static and the behavioral views of the system, and the functional requirement model defined by the use case model reflecting the functional view of the system. The transformation of the CIM allows us to generate the PIM level represented by two models: The domain classes model which gives a structural view of the system at this level, and a model that describes the behavior of the system to each use case.
