| Abstract: | As the shortage of traditional cube algorithm computing data set of complex dimension hierarchy,this parper introduces an aggregate algorithm of an aggregate algorithm of hierachical cube operation based on theory of quotient space.The experiments show that this algorithm performs more effectively computation performance than traditional one. |
