OLAP An OLAP (On-line Analytical Processing)

deal with Historical Data or Archival Data, and it is characterized by relatively low volume of transactions. In addition, the Queries needed for these systems are often very complex and involve aggregations as for OLAP systems the response time is an effectiveness measure.
