A method and a system for executing a general database processing independent of a specific user-defined function are provided. In an implementation method, index definition information for setting a specific user-defined function in correspondence to a specific index which is used to carry out an index access to data in a database region is created, and module definition information for setting the specific index which is used to carry out the index access to the data in the database region in correspondence to an implementation module for subjecting the data in the database region to a specific processing is created. When it is determined in response to a processing request for the database issued from an end user, that the user-defined function contained therein is set in correspondence to the specific index on the basis of the index definition information, a specific implementation module for carrying out an access using the specific index is selected from the module definition information, and a database processing is performed using the implementation module thus selected.
