PURPOSE:To execute a rational registration processing at the time of simultaneously updating common data without deteriorating work efficiency. CONSTITUTION:A host device 1 is connected to work stations 2A and 2B through a network. In the network stations 2A and 2B, the processing is executed by using data copied from a master file 11. A data generation management part 13 executes update-registration and branching-registration of data processed in the work stations 2A and 2B to the master file 11 in accordance with the transmission/reception of data between the work stations 2A and 2B. The data generation management part 13 registers information related to branching registration to a master data table 11a and the branching relation management table of a branching relation management part 12 when it has branching- registered data to the master file 11.
