Abstract

PURPOSE:To reduce overhead, by decentralizing the data base to plural systems and by transmitting update request, update data, and reference request connected to the stack queue to the other processor when the application program of one processor refers to the data base. CONSTITUTION:In respect to the update macro of the data base of application program 4 of own system 1, it is checked by access module 5 whether the data base exists in its own system or not; and if it does not exist in its own system and is update request, update request is generated in buffer 6. Next, the reference macro from program 4 is checked by module 5; and if the data base of the macro belongs to another system and the reference system, reference request is generated in buffer 6. It is checked whether update request is connected to the stack queue or not; and if update request exists in the stack queue, update request and reference request are stored in buffer 7 of another system 2 simultaneously through communication bus 9, and thus, overhead in communication is reduced.
