OLAP is one of important techniques in DSS.The computation of CUBE is the basis of ad hoc query in OLAP.In order to advance the corresponding to querying,we must pre aggregate data in tables or multidimensional databases.Typically,the computation of CUBE consists of materializing strategy,the choice of materialized paths and its optimization and CUBE algorithms.Based on them,this paper analyzes and expatiates concepts,strategies,steps,methods and performances about the computation of CUBE in details.
