Abstract: Data Warehouses (DWs) store historical information which support the decision-making process. Since this information is crucial, it has to be protected from unauthorised accesses by defining security constraints in all stages of the DW development process. In previous works, we applied the Model-Driven (MDA) philosophy to define secure DWs using several security models and transformations. Nevertheless, our conceptual model makes it possible to define complex security rules with OCL expressions which are not transformed automatically. This paper deals with this problem and completes our approach improving our conceptual metamodel and defining new transformation rules. Finally, an application example is shown.
