To execute a user definition function at a high speed by carrying out the link processing between a program object of the user definition function and a program object of a DBMS(data base management system) before a data base is activated.
The link processing is carried out between a program object of a user definition function and a program object of a DBMS before a data base is activated. An AP(application program) 201 where the user definition function is described on a DBMS interface 202 is generated. Then the AP 201 sends the interface 202 to a DBMS 203. In the DBMS 203, the interface 202 performs a syntax analysis in a syntax analysis process 204. Then a DB access process 205 is carried out, based on the result of the process 204, a user definition function activation process 206 is carried out with the function name and position, etc., used as parameters and the result of the process 206 is returned to the AP 201. As a result, the execution result of the user definition function can be returned to a user.
