ABSTRACT:
A system and method for storing within, and retrieving from, a computer database values of a multidimensional array in which storage locations are allocated within each storage node of the database corresponding to a dimension of the array only for the database-pointers actually stored within the storage node. An indicium is stored with each database-pointer to identify the element of the array's dimension to which the database-pointer corresponds. In an alternative embodiment, a sub-storage area, with sub-storage locations allocated for each of the elements of the dimension to which the storage node corresponds, is associated with each storage node, and an indicium is stored within each sub-storage location indicating whether a database-pointer exists in the associated storage node corresponding to the associated element. A hierarchial table of calculation rules also is provided for determining values which are calculated from other values within the array. Each of the table's rules defines one or more storage locations within the array and provides a formula for calculating the values applicable to those locations.
