PROBLEM TO BE SOLVED: To cope with increase in scaling accompanying higher performance, relating to scaling out of a distributed database system, caused by division of the database system which requires real-time updating into a plurality of database domains. SOLUTION: In a multi-transaction process distributing a large scale database system into a plurality of database domains and updates a database object across the plurality of database domains in real time, the multi-transaction process is performed at a higher speed, by applying a partition topology technology or replication topology technology to a database meta-information storage management part inside a database meta-information management repository device, for exchanging and synchronization of meta information, such as status information.
