PROBLEM TO BE SOLVED: To smooth and ensure sharing of data between network-connected computers. SOLUTION: A value showing the only and one state of a database 11 of a client 11 is derived from data held in the database 11, and a value showing the only and one state of a database 21 of a server 2 is derived from data held in the database 21. Both the values showing the only and one state are mutually compared as needed, and the time when different values are detected is recognized as the time needing data linkage of the database 11 owned by the client 1 with the database 21 owned by the server 2, and necessary data are transmitted from the client 1 to the server 2.
