The concept of data warehousing provides troublefree
organization and easy maintenance of large volume of data
in addition to quick retrieval and effective analysis in the
desired manner and depth required from time to time. As the
data volume increases continuously, the speed requirements for
processing the data so as to figure out the meaning of this data
are also required to be increase drastically. The solution of
above problem is instead of accessing from base table every
time ,create pre-calculated result of a query posted to the data
warehouse called as materialized view to increase the speed of
queries posted to a data warehouse. The major problem is, how
to select which views or queries are more desirable out of many
queries because it is not feasible to create materialized view of
each query due to storage cost and materialized view
refreshment cost so that effective materialized view selection
framework is required for data warehousing system. However,
the materialized view selection is based on the various
parameters like access frequency, processing time, storage space
etc.

As materialized view store the precomputed data it is used
to improve query performance, by minimizing query
processing time. But due to view maintenance cost it is
impossible to create materialized view of all the queries.
Thus how to select the set of queries to be materialized so
that query performance increases significantly and storage
cost for storing materialized view minimized.
