PROBLEM TO BE SOLVED: To facilitate quick table manipulation in terms of operation while suppressing I/O between a database management device and a database device. SOLUTION: Upon receiving a definition request, a processor of the database management device changes table definition information so that a specific table is targeted for special processing. The processor selects an index that is set on the table based on index definition information related to the table, and registers the index in the index definition information so that the index is targeted for special processing. Furthermore, the processor places the index in a specialized memory based on the index definition information while transferring the table from a buffer to the specialized memory based on the table definition information.
