Bitmap Index Implementation

Abstract

Bitmapped indexes are useful in processing complex queries in decision support systems, and they have been implemented in several commercial database systems. The purpose of this project is to implement a bitmapped index and R-trees using the Berley GiST package and compare these indexing methods.

We have implemented the bitmapped indexing using the GiST B-Tree extension. Functions have been developed to create a bitmap index and efficiently retrieve data from the index.

We also present a study of the various bitmapping schemes and their merits.

The R-tree implementation has been planned as future work.
