Abstract
In a multi-dimensional data management method in a database management system, a collection of members constituting each dimension is grouped and page indexes constituted by entries corresponding to combinations of member groups of each dimension are assigned to a memory unit. A set of member groups corresponding to input data is determined from a set of members of dimensions specifying the input data and an entry of page index corresponding to the set of member groups is obtained. When a page number is not registered in said obtained entry, a page is assigned in the memory unit and the page number of the page is registered in the entry. The input data and identification information of the data are paired to be stored in the page having the page number registered in the entry.
