Abstract: PURPOSE:To improve the data processing efficiency by referring to a key list pages where the key values and the pointers of records stored in an overflow data area in the ascending order of key values. CONSTITUTION:When a retrieving request is received from a user program 1, a data processor 2 retrieves the index pages 4-1-4-5 of an index part 31 of an auxiliary storage 3 through a key retrieving means 21 based on the requested key value and obtains the corresponding data pages 5-1-5-3.
