Abstract: - The contribution of this paper relates to the ability of bitmap indices to support OLAP-oriented queries and analyses. On one hand, the Bitmap index access method improves the serial data access performance. On the other hand, the Bitmap index semantics and use allow one to include the definition and management of complex classes dynamically investigated for analytic purposes. In this novel approach, bitmaps are defined at a higher abstraction level than the traditional indices and bitmaps. In fact, they allow the analytic or decisional user to also categorize objects which satisfy any legal relational query.
