PROBLEM TO BE SOLVED: To provide a distributed information synchronization system and a distributed information synchronization method capable of performing synchronization processing even between databases whose table structures (data formats) are different.SOLUTION: An information change detection section 102a of an information holding device 10a detects that information has been changed, and transmits the synchronization information of the changed information to a synchronization information transmission section 101a, and the synchronization information transmission section 101a transmits the synchronization information to an information cooperation device 20. A synchronization information arithmetic section 201 of the information cooperation device 20 reads synchronization rule information, and performs arithmetic processing in accordance with the synchronization rule information, and transmits the synchronization information subjected to the arithmetic processing to a synchronization information transmission section 202, and the synchronization information transmission section 202 transmits the synchronization information subjected to the arithmetic processing to information holding devices 10b and 10c in accordance with the synchronization rule information. Synchronization processing sections 103b and 103c of the information holding devices 10b and 10c update information holding device holding information 104b and 104c with the received synchronization information. |
