Executive Summary

The Data Warehouse (DW) design is based on MultiDimensional (MD) modeling which structures information into facts and dimensions. Due to the confidentiality of the data that it stores, it is crucial to specify security and audit measures from the early stages of design and to enforce them throughout the life-cycle. Moreover, the standard framework for software development, Model Driven Architecture (MDA), allows them to define transformations between models by proposing Query/View/Transformations (QVT). This proposal permits the definition of formal, elegant and unequivocal transformations between Platform Independent Models (PIM) and Platform Specific Models (PSM).
