Abstract
A data generalization apparatus that can perform generalization processing on large-scale data at high speed using only a primary storage device of a small capacity. Included is a rearrangement unit that rearranges the attribute values in a secondary storage device in accordance with an order of arrangement of the attribute values in a generalization hierarchy in the secondary storage device, an attribute value retrieval unit that retrieves some of the rearranged attribute values from the secondary storage device into a primary storage device, and a generalization hierarchy retrieval unit that retrieves a portion of the generalization hierarchy from the secondary storage device into the primary storage device. Further, there is a generalization processing unit that executes generalization processing based on the attribute values retrieved into the primary storage device and the generalization hierarchy retrieved into the primary storage device, and a re-rearrangement unit.
