A Mixed Approach for Data Warehouse Conceptual Design with MDA

摘要

This paper is developed in the context of conceptual design of Data Warehoses (DWs) with Model Driven Architecture (MDA) (a methodology for DW conceptual design). The method is made up of a set of transformation rules as a mechanism to extract multidimensional schemas from the conceptual description of the operational database. Next the generation of multidimensional schemas, we apply user requirements to guide the selection of the multidimensional schema that is supported by the operational database and most likely satisfy user requirements.
