Abstract: - The use of bitmap indexes for representing analytical views of user’s data is presented. This approach differs from the conventional definition and use of bitmap indexes in that they are defined not only to index different domain attribute values, but also for pre-computing any legal relational algebra query expression of the user for the analytic purposes. The paper illustrates the meaning of the analytical bitmaps and their application for solving problems of data integration and logical association between data. Furthermore, a fast access algorithm to enquire analytic bitmaps is presented.
