ABSTRACT:
In order to manage a plurality of sets of multidimensional data positioned in a specific area of a computer, when hierarchically dividing a first area within the specific area into second areas that are to constitute child areas thereof, a decision is made as to whether or not a division condition, which is based upon the state achieved when the sets of multidimensional data are allocated to the first area and the state achieved when the sets of multidimensional data are allocated to the second areas, is satisfied. When it is decided that the division condition will be satisfied, the first area is hierarchically divided into the second areas to allocate the sets of multidimensional data to the second areas.
