A materialized view is a stored summary containing pre-
computed results.As the data is pre-computed, materialized
views allow for faster query answers
In warehousing applications, large amounts of data are
processed and similar queries are frequently repeated. If
these queries are pre-computed and the results stored in
the data warehouse as a materialized view, using
materialized views significantly improves performance
by providing fast lookups into the set of results.
A Materialized View generally behaves like a Index and it
can also have any Number of Aggregates and Joins.
