=head1 DESCRIPTION

dw-nav will create the base of a simple Data Warehouse Navigator.

=head2 AGGREGATE NAVIGATOR

One of the main features of the Data Warehouse Navigator is the
transparent Aggregate Navigator.

The Aggregate Navigator will intercept SQL queries and generate
aggregate tables, whenever is possible.

The use of aggregate tables can speed up Data Warehouse by 100s
or 1000s of times.
