Abstract

PURPOSE: To efficiently use the storage area of a data base by providing a different information storage means stored with ioformation on the difference between a record at a specific point of time and a record after the specific point of time which is stored in a record storage means.
CONSTITUTION: A data base control means 121 alters the record stored in the record storage means 111 of the data base 110 after the specific point of time according to an indication from a 1st information processing means 101 and stores the difference information on the difference generated from the record at the specific point of time as a result of the alteration in the difference information storage means 112. According to the difference information, the record at the specific point of time before the alteration by the data base control means 121 is restored and supplied to a 2nd information processing means 102. Consequently, the 1st information processing means 101 and 2nd information processing means 102 share records which are not altered from the specific point of time to eliminate the double storage of the records, and the storage area of the data base can be utilized efficiently.
