Abstract:
Recently Data Warehouse System is becoming more and more important for decision makers. Most of the queries against a large Data Warehouse are complex and iterative. The ability to answer these queries efficiently is a critical issue in the Data Warehouse environment. If right Index Structures are built on the columns, performance of the queries, especially ad-hoc queries will be greatly enhanced. In this paper, we have concentrated on various implementation issues of Simple Bitmap Indexing and their analysis.
