RETRACTED: Model-driven development of OLAP metadata for relational data warehouses (Retracted Article)

We propose a model-transformation architecture with which to obtain both the database schema of a data warehouse and the required OLAP metadata for end-user tools to intuitively query the underlying schema. The main benefit that this architecture provides is a set of mappings that will allow designers to effortlessly obtain various types of OLAP metadata for several kinds of tools and users during the simultaneous generation of the database schema. Both processes are automatic and integrated. As a proof of concept, our approach is implemented in the Eclipse Modelling Framework, thus showing its feasibility and usefulness. (C) 2011 Elsevier B.V.
