PROBLEM TO BE SOLVED: To provide a distributed operation supporting system capable of being easily incorporated in a conventional database system. SOLUTION: This distributed operation supporting system is provided with a master distribution server 2 constructing the sub-database 2a as a subset replica of the operation database 1a constructed in the host computer 1, and connected to the host computer in a state that they can exchange the data with one another, and a slave distribution server 3 constructing the read-only- type sub-database 3a by the snapshot of the sub-database acquired from the master distribution server. A client terminal 4 acquires the data from the sub- database of the slave distribution server, creates the desired database, and transfers the latest data to the master distribution server.
