摘要
It is a purpose of this invention to achieve Scale-Out of the distributed database system that assumes a real-time update to be a requirement and which is achieved by dividing the database system into two or more database domains. This is to achieve handling of even larger scale databases while providing even higher performance. Assuming that the large-scale database system has been distributed to two or more of above-mentioned data base domains, in multi transaction processing with real-time update of the database object across two or more of above-mentioned database domain, this invention is achieved by executing the above-mentioned multi transaction processing to the database meta information storage management part in the database meta information management repository device by applying partition topology technology or replication topology technology for exchange and synchronization of meta information such as status information etc. at even higher speeds.
