PURPOSE:To lighten the load on a user required for production of an application program by using a data control program to perform the transfer and the exclusive process of transactions. CONSTITUTION:A data control program 52 receives a transaction 105b from an application program 51 and performs an exclusive process to inhibit the processing of other transactions against the corresponding data on its own data base 53 by means of a record or block excluding function included in an OS. In a secondary system, a data control program 62 performs an exclusive process to a data base 63 at reception of the transaction 105d. In such a way, the load is extremely reduced for the application program that has so far taken charge of those said processes. |
