ABSTRACT:
In a database management system including a request reception server and a plurality of execution servers, each having a plug-in program module incorporated by a user, the request reception server analyzes a processing request from the user to determine whether or not the plurality of execution servers require currently unidentified input parameters when executing external functions in their plug-in modules, based on a definition information table created from descriptions of interface specifications for the plug-in program modules. When it is determined that the execution servers require such input parameters, an external function in the plug-in program module in the request reception server is executed to previously acquire the unidentified input parameters. The request reception server creates an execution processing procedure code, to be executed by the plurality of execution servers, assuming that the unidentified input parameters have already been inputted, and passes the execution processing procedure code together with the input parameters acquired by the request reception server to the plurality of execution servers.
