Zusammenfassung:PROBLEM TO BE SOLVED: To provide a database system for executing synchronization processing and matching processing of databases between an operation system and a standby system, without interrupting service provision in the operation system, and without requiring a resource for buffering an updated content during synchronization. SOLUTION: The database system has databases duplicated by the operation system 10 and the standby system 20, and the operation system 10 and the standby system 20 include respectively control parts 120, 220 for imparting respectively sequence numbers incremented when updated, to data of the databases 130, 230, and for synchronizing and matching the databases between the operation system and the standby system, using the sequence numbers.
