data warehousing
(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.
