PROBLEM TO BE SOLVED: To alleviate complication of operation for a user and prevent occurrences of an information mismatch due to re-inputting by minimizing re-inputting of information when updating definition information. SOLUTION: In a method for updating the definition information in an data extraction, an associated information table associating user re-definition information in an extraction origin database with the definition information in an extraction destination database is created to be stored into a memory. When updating the user re-definition information, a table part not needed to be changed is remained unchanged even when the information table is updated, a new table part is created as associated information needed by the updating, and an associated information table corresponding to the updated user re- definition information is created by adding the table part newly created to the remaining table part in the memory.
