چکیده
|
The data warehouse size and query complexity may cause an unacceptable delay in decision support queries. a basic condition for the success of a data warehouse is the capability to supply decisionmakers with both precise information and best response time. for this purpose, the concept of indexed views is used. indexed views help to speedup query processing and reduce the response time for tracing queries, especially for queries about past histories.
