To actualize a communication from a client to a server object without any previous awareness of the network where the server object is present and a communication system to be used.

The decentralized object system comprises computers 1, 2, and 3 which are interconnected by the network. A client 11 based upon decentralized object technology mounted on the computer 1 communicates with server objects 21 and 31 through the network. The computer 1 is provided with network connection parts 13 and 17 which performs communication by using a previously set communication system and a network management part 12 specifies a network connection part and a communication system corresponding to a server object to be communicated with by using information stored in a database 15 and transfers transmit data from the client 11 to a specified network connection part.
