The notion of data warehouse can be defined as subject-oriented, integrated, nonvolatile and time-variant collection of data in support of making management's decision effectively, for the success of data warehouse accurate and timely consolidated information as well as quick query response times is the fundamental requirement. To avoid accessing from base table and increase the speed of queries posted to a data warehouse, the authors can use some pre-computed intermediate results from the query processing stored in the data warehouse called materialized views.
