ABSTRACT:
An object of the present invention is to perform data clustering while preventing the processing speed from decreasing while maintaining accuracy. A block division section3divides a block received from a DB access section2into sufficiently small blocks. A block storage section8stores blocks supplied from the block division section3and hierarchical relationship between the blocks. A block integration section5integrates blocks and groups in the order from a hierarchically deeper position to a shallower position based on the stored hierarchical relationship.
