We introduce the use of Bitmap indices as very useful tools to represent analytical views of user's data. This approach differs from the conventional definition and use of bitmaps in that it allows us not only to index different domain attribute values, but also to pre-compute (any) legal relational algebra query expression from the user for analytic purposes. The paper discusses deeply the meaning and our use of analytical bitmaps, and shows some applications using a real context for solving integration and analytic problems.
