Executive Summary

Quick response time and accuracy are important factors in the success of any database. In large databases particularly in distributed database, query response time plays an important role as timely access to information and it is the basic requirement of successful business application. A data warehouse uses multiple materialized views to efficiently process a given set of queries.

Selecting a suitable set of views that minimizes the total cost associated with the materialized views is the key component in data warehousing.
