PROBLEM TO BE SOLVED: To improve the processing performance of an encrypted query in a database with a partially encrypted column.;SOLUTION: This query processing system modulates a query of a requesting user based on an unencrypted database structure to a query of an encrypted database structure about a database management system (DBMS) 100 for managing a database 110 with a partially encrypted column, and the DBMS processes the query. Therefore, the DBMS can process the query irrespective of whether or not the query includes an encryption-related item, and encrypted query-processing performance is remarkably improved.;COPYRIGHT: (C)2009,JPO&INPIT
