data mart
(foldoc) | data mart
A type of data warehouse designed primarily to
address a specific function or department's needs, as opposed
to a data warehouse which is traditionally meant to address
the needs of the organisation from an enterprise perspective.
In addition, a data mart often uses aggregation or
summarisation of the data to enhance query performance.
However, it is important to maintain the ability to access the
underlying base data to enable drill-down analysis as
necessary.
