PROBLEM TO BE SOLVED: To provide a mechanism guaranteeing the issue of a later operation command after the execution of a previously issued operation command in operation executed to shared data shared with a plurality of processes so as to remove restriction on the timing of operation command issue. SOLUTION: In a system wherein each of the plurality of processes holds and uses the shared data shared with the plurality of processes connected via a network, the identity of the shared data held by each the process is maintained. When an operation request to the shared data is generated, an operation event showing the operation request is issued (T2501). By user's prescribed operation, a digestion event is issued (T2503). When an operation event responding to the issued operation event is received from a server, the operation to the shared data is executed according to the operation event. Until a digestion event corresponding to the issued digestion event is received (T2506) after the issue of the digestion event, the issue of the operation event based on the operation request is forbidden.
