PROBLEM TO BE SOLVED: To obtain a high speed response to an application and flexibility in relation to a service stop in the other base. SOLUTION: An application processing unit 11 executes an application; a message queue processing unit 13 sequentially saves synchronization requests from the application including difference information between storage data 12A and 22A generated by update; and a data synchronization transmission processing unit 14 acquires the synchronization requests from a message queue processing unit 13 in the order in which the requests are saved to be transmitted to an information processor 20 via a communication network 30. A data synchronization reception processing unit 25 receives the synchronization request from an information processor 10 to update the storage data 22A on the basis of the difference information included in the synchronization request.
