PROBLEM TO BE SOLVED: To realize a virtual space sharing among the plurality of independent machines, while autonomously performing linkage, and to collectively perform operations with a possibility to have a different name and operation on the plurality of machines with a possibility to be different in communication system from one machine as a part of a device where the plurality of machines are autonomously linked, while securing extensibility in both the operations at a side to request collective performance at a caller side and a side to be called. SOLUTION: Each machine in the distributed environment (regardless of physical or virtual implementation) includes a spatial management means for individually holding/managing the replica of master information stored in a data base; and a remote operation collective calling means for collectively and remotely calling the arbitrary operation, which is arranged in the plurality of machines, from a certain machine.
