PURPOSE:To reduce transfer data quantity by managing without transferring an access result accessed once in the case that the same data base is accessed many times from a remote data base access using part by using an identifier. CONSTITUTION:A data base access result which the remote data base access using part 11 requests to a remote data base access execution processing part 12 and is executed is transferred after being attached with the identifier, and it is held in the data base access result data holding means 15, 16 of the using part as being attached with the identifier. As for the data accessed once, the remote data base execution processing part 12 transfers only the identifier to the using part 11. Thus, transfer data after the second time can be reduced and the data can be efficiently transferred.
