PURPOSE:To facilitate system expansion, by requesting a relational type data base control mechanism through an interface, at translation. CONSTITUTION:When a microinstruction CALL is generated, a string of RDB access commands is passed to a relational type data control system 9 through an interface at execution 8. This control system 9 uses a syntax check part 10, tree structure generation part 11, optimization part 12, and an operational generation part 13 to generate an operational list 14. This generated list 14 is passed to a data base control system 15 and executed. RDB access commands from a TSS terminal 6 are sent to the control system 9 through the interface 8. Then, this system 9 generates the operational list 14. This list 14 is executed by the data base control system 15. |
