data mart - Free On-line Dictionary of Computing (26 May 2007) :

  data mart
  
     <database> 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.
