> 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.
