PURPOSE: To continue the processing for a certain period by generating a holding type object without giving any inquiry to a server process when a client process has no processing object type.

CONSTITUTION: This device includes an input device 101, CPU 102, main storage (RAM) 103, ROM 104, secondary storage 105, output device 106 and network interface 107. Then the object data are acquired from a server and an object type is acquired from the object data, and a client itself decides whether it has its own object type or not. If the client has its own object type, the relevant object is generated and the due processing is carried on. If the client has no type of its own object, the client decides a holding object type to process it by itself and generated a holding type object to carry on the due processing.
