In addition, the file processor 20 is common to each of the terminal machines 10A to 10D, and its upper device 3
It is connected to the 0-store store processor. This host device 30 has another file processor (2
0) is also connected and manages the entire data.

The file processor 20 includes a product file, a first cumulative area 23T, and a second cumulative area 23.
An accumulation file 23 that forms H etc. is provided.
This merchandise file is provided to reply merchandise data to an inquiry from each of the terminal machines 10A to 10D. In the first cumulative area 23T, each terminal device 10
The product sales registration data from A, 10B, ... Is stored. For details, by department (basic department, discount, disposal, inventory),
It is sorted and stored by transaction, time zone, group, etc. These stored data are accumulated, for example, on a daily or weekly basis. On the other hand, in the second cumulative area 23H,
The data stored in the first cumulative area 23T is dropped. For example, monthly data can be accumulated. Therefore, the data stored in the second cumulative area 23H can be requested from the host device 30. That is, the first cumulative area 23T is used in relation to each terminal machine 10, and the second cumulative area 23H is used in relation to the host device 30.
