ABSTRACT:
Data access in a data base management system is controlled. The method for controlling the data access in a computer having a first memory and a sub memory, both for storing data required to execute a program, including at least one data operation instruction comprises the steps of transferring data required by the data operation instruction from the sub memory to a location in the first memory, prior to execution of the data operation instruction, and informing the data operation instruction of the address of the location of the data required thereby, prior to execution of the data operation instruction. The apparatus for controlling data access comprises a sub memory for storing a data base and programs including at least one task unit having at least one data operation instruction, a first processor for executing each task unit stored in the sub memory, a first memory for storing programs and data executed by the first processor, a second processor connected to the sub memory, and a second memory for storing programs and data executed by the second processor, whereby the first processor executes the task unit read out from the sub memory, while the second processor reads out the data from the sub memory specified by the data operation instruction included in the task unit, based on the parameter supplied from the first processor and stores the data read out from the sub memory and corresponding addresses in the first memory.
