Transformation Rules According to MDA Approach for a Dependable Data Warehouse System

Data Warehouse systems can extract relevant information from a large volume of data. Since the purpose of this information is to facilitate the decision making, it’s important to ensure Dependability of the system which delivers it. Thereby the dependability’s requirements must be taken into account in the early stages of the development process of the Data Warehouse system (DWS). In previous work, we proposed to adapt the MDA (Model Driven Architecture) approach to model dependable DWS, by defining CIM (Computation Independent Model) and PIM (Platform Independent Model) of dependability’s aspects. And we also demonstrated a relationship between the two models. In this article, we focus more on transformations from the CIM to PIM to ensure automatic management of these models on the one hand, and to keep traceability’s link of dependability’s requirements through the different stages of MDA on the other hand.
