PURPOSE:To uniform the capacities of data for a relational model between respective processors to execute set operation and improve the efficiency, by coupling between two processors in a successively divided group through a common memory. CONSTITUTION:Data uniformed by processors P0, P1, P2 P3 are stored in data base storage devices M0-M3. Data capacities between processors are uniformed by a switch group connected to respective processors and controlled by a controlling device. A switch S1 in the switch group supplies the output of the processor P0 to the memory M1, the output of the processor P1 to the memory M0, the output of the processor P2 to the memory M3, and the output of the processor P3 to the memory M2 so as to be crossed each other. |
