  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).
