PURPOSE:To speed up the coupling operation of a related data base by introducing the parallel processing mechanism of a macro level and a micro level, and a pipeline processing mechanism between processings. CONSTITUTION:A processing request of the coupling operation reaches a main control processor 7 from a host processor 5 through an LAN 6. The main control processor 7, receiving the processing request, requests an auxiliary control processor 20 of respective unit 8 to process it, through a connection 11. The auxiliary control processor 20 reads out an object attribute data from a unit corresponding data base storage 22, and starts the processing to load a unit corresponding association memory 21 all at once. The auxiliary processor 20 requests a broadcasting mechanism 23 to process a broadcast processing. The broadcasting mechanism 23 reads out the object attribute of the relation of another side of a coupling object from the unit corresponding data base storage 22, and transfers it to other unit through a bus 9.
