data warehousing
<database> (Or corporate data warehouse, CDW) Any system for
storing, retrieving and managing large amounts of data. Data
warehouse software often includes sophisticated {compression}
and {hashing} techniques for fast searches, as well as
advanced filtering. A data warehouse is often a {relational
database} containing a recent snapshot of corporate data and
optimised for searching. Planners and researchers can use
this database without worrying about slowing down day-to-day
operations of the production database. The latter can be
optimised for transaction processing (inserts and updates).
Compare {data mart}.
