As described above, data having a plurality of destinations having a hierarchical structure
In the data communication system, the transmission source 2 has the above hierarchical structure.
Data is transferred to the destination of the lower layer via a certain higher layer.
Destination index information indicating that the data is to be transmitted is shared with the data.
First transmitting means 4 for transmitting to the higher hierarchy,
In the upper layer, based on the received destination index information
Then, the received data is transmitted to the corresponding lower hierarchy 10.
And a second transmission means 8. this
In the invention having such a configuration, the transmission source 2 passes through the higher hierarchy 6
And send data to the destination of the lower hierarchy 10
Is transmitted by the first transmission means 4 of the transmission source 2.
Destination index information indicating data, together with data, in the upper layer
Send to 6. In the upper layer 6, the second sender
Stage 8 is based on the destination index information received with the data.
And transmits the received data to the corresponding lower layer 10.
You. Manage the destination of the lower hierarchy in the hierarchical format with the upper hierarchy
Destination identification according to the destination index information attached to the data
Judge whether there is any information, and autonomously send the destination identification information.
And decided to transmit the data.
Facilitate trust management. The present invention is shown in FIG.
The transmission data is transmitted to the host computer for each transmission destination.
An email system that registers and performs data communication
It is characterized by having done. The invention having such a configuration is
Register the transmission data for each destination in the
Hierarchical structure of the destination of the e-mail system for data communication
Data from the source via the higher hierarchy
This is transmitted to the next level. In this invention
Also enjoy the same effects as the invention described earlier.
I can do it.

FIG . 2 shows a configuration of a personal computer communication system for performing personal computer communication. Although not shown, the head office, each branch, each dealer, and each store have a personal computer for performing personal computer communication, a hard disk connected to the personal computer, and the like. As in the case of the conventional personal computer communication system, the personal computer is additionally provided with a data transmitting / receiving device. When transmitting and receiving a transmission record, a reception master file, a reference file, a work file, and a transmission file are generated on the hard disk and used for personal computer communication. Then, a processing program for performing processing for personal computer communication, a receiving program and a transmitting program for personal computer communication are stored in a hard disk or the like in the personal computer.

The processing flow executed by the processing program for personal computer communication is shown in FIG. 3, FIG. 4, and FIG. The operation of the personal computer communication system embodying the present invention configured as described above will be described below.

Now, for the sake of explanation, the head office 10 to the A branch 12
The transmission record (data to be transmitted) delivered to the B dealer 14B via A is stored in the A dealer 16A, the B dealer 16B, and the C dealer.
It is to be transmitted to the store 16C (see the shaded portion in FIG. 2).

FIG. 6 shows an example of a transmission record transmitted from the A branch 12A to the B dealer 14B. The B dealer 12B stores the received record in the received file (see FIG. 6). Using the product code (destination index information) in the received record as a key, a reference file (see FIG. 7) of the B dealer 12B is indexed to read out a related department code (destination identification information) (see S1 in FIG. 2). .

If there is no relevant department code corresponding to the product code (see NO in S2 in FIG. 3), the B dealer 14B does not perform the process of discharging to the work file. If there is a related department code corresponding to the product code (YES in S2 of FIG. 3)
4), as shown in FIG. 4, the transmission address in the received record is set as the transmission source address (see FIG. 4A), and the related department code matched in the reference of the reference master is set as the transmission destination address (FIG. 4). 4b).

The record thus generated is stored in the work file as a record to be transmitted to the great-grandchild hierarchy (see S4 in FIG. 4, FIG. 8). The transmission records in the work file are stored in the stores 16A, 16B, and 16C of the great-grandchild hierarchy.
A file is edited for each of the stores 16A, 16B, and 16C (see S5 in FIG. 4). The file generated here is a transmission file.

Each of the stores 16A, 16 thus generated
By transmitting a transmission record stored in a file for each of B and 16C to a known transmission program and registering it in a host computer for personal computer communication, each of the stores 16A and 16C
B and 16C (see S6 in FIG. 4). Each store 1
6A, 16B, and 16C receive data addressed to themselves when registered in the host computer for personal computer communication.

Since the above-described automatic processing is performed, the B dealer 14B does not need to perform the complicated retransmission processing as in the related art, so that the B dealer 14B can save time and labor. Is no longer required, so that an operation error can be prevented.

The above-described processing is performed between the head office and the branch.
Since the same applies between the branch and the dealer, the above-described effects can be enjoyed between them. Note that, in the above-described embodiment,
Although the case of four hierarchical formats has been described, the present invention can be applied even when the hierarchical format is further deepened.

[0021]

As described above, according to the present invention, transmission destinations in a lower hierarchy in a hierarchical format are managed in a higher hierarchy, and transmission destination identification information is associated with transmission destination index information attached to data. It is determined whether or not the data is transmitted, the destination identification information is determined autonomously, and the data is transmitted, thereby facilitating the management of the destination.
