摘要: A highly reliable online system is disclosed which provided with a backup computer center (sub-online system) in addition an original (main order to improve the reliability of system. With respect database, main database database) while sub-online (sub-database) duplicate database. The and are connected through transmission path. Information on update performed transferred path thereby sub-database manner similar Terminal units normally system, wherein updated by transactions inputted from terminals. When failure occurs terminals changed over be allow transaction processing continued. Further, there control for synchronizing contents between when center, recovery recovering or failures integration integrating both they independently due like.
