PURPOSE: To accelerate a DB operation processing from a user program by issuing the execution request of a registered DB operation by setting the identification name of the registered DB operation as a parameter when it is executed.
CONSTITUTION: A pre-processor part 35 issues a pre-compilation request to a data base managing system DBMS 40b, and reads a source text in a source program 21b to be pre-processed one by one. When the source text is not a DB operation text, the source text is written out as a program after change. When the source text is the DB operation text, the pre-compilation request is issued to the DBMS 40b. A correspondence table in a DB 50 is updated based on the above result, and the DB operation text is converted to the source text which issues the execution request of the registered DB operation, and writes it to a source program after change. After such processing is performed for all source texts, a pre-compilation completion request and a storage request to the DB 50 of the correspondence table are issued to the DBMS 40b, then, the processing is completed.
