MULTI-DIMENSIONAL DATABASE MANAGING METHOD

PROBLEM TO BE SOLVED: To select/adopt a multidimensional database storage method with high retrieval efficiency in a system by calculating the value of a virtual cell and storing the value in a disk when all the reference cells of the virtual cell are arranged. SOLUTION: The major-dimensional member information table 716 of a storage required virtual member is obtained from virtual member ID 723 of a storage required virtual member and a virtual member information table 724 is obtained from the calculation expression offset 720. It is checked whether cell data on all reference members 733 in a reference member list 732 displayed by a reference member list offset 728 is already stored or not. When all the members are already stored, the required cells are arranged in the storage required virtual cell. The storage required virtual cells are calculated by a calculation expression list 730 designated by a calculation expression list offset 726. The storage required virtual cells are stored in a temporary storage area. The cell of input data and the stored storage required virtual cells are collectively stored in a disk device.
