> Materialized views are useful as ways to store either alternate versions of data (e.g.
same data, different sort order) or derivatives of data sets (e.g. commonly used aggregates).
 It is useful to store these as materialized views rather than as tables because it can give
the optimizer the ability to understand how data sets are related.
