PURPOSE:To enable a specific applied program to access to a data store part in accordance with the contents of work by selecting the work to control the effective items of a control table which controls the accessible applied program according to the work. CONSTITUTION:A work selecting circuit 13 outputs a selection signal A when the work A is performed. Then a control table 12 informs a data base control circuit 11 that all applied programs RO-WO are ready for working. Therefore the programs RO-WO are controlled by the exclusive control based on a table T1 to perform the on-line work. Then the table 12 informs that programs RO, ER and CER are ready for working when a selection signal B is outputted. Then the circuit 11 performs the exclusive control based on the table T1 and also stops the working of programs MD, UP and WO by the working indications of only programs RO, ER and CER. |
