Abstract

A query processor (query compilation and execution) is an essential component in any database management system (DBMS). Specifically, query compilation transforms user queries into a sequence of database operations, while query execution executes those given operations. Retrieve Information from the OLAP Storage is very important task, but because of large amount of OLAP data it’s taking tremendous time for the execution of the query. In this paper, we shall cover algorithm for the SELECTION operator (OLAP Algebraic Operator), which is used to access the data of the OLAP storage.
