[0002] In recent years, client-server type systems have become widespread, and in many cases, distributed computers are installed at various locations in a company. In the system configuration, an increase in the amount of data or addition / change of business processing causes a change in the server environment and the client environment to be used, so that the operation load is extremely large. For this reason, it is desired to perform processing using electronic mail and to improve the efficiency of system operation.

[0003]

2. Description of the Related Art Conventionally, in the configuration of a distributed system, 1
In performing one business process, the client needs to know which server holds the corresponding data or which server requests the process.

[0004] In addition, it is necessary to manage a server and / or a client for each business process as a series of flows up to the execution result of the process. In that case, while the client is executing one process, even if there is another process, it cannot be executed simultaneously.

Further, operability of system processing could not be unified / standardized due to characteristics or limitations of a system developing model, a development language, and the like.

[0006]

According to the conventional development method,
In both conversational and batch processing types, the client needs to know which computer does what processing. There was a problem that a large amount of maintenance work was required when changing the environment.

[0007] Further, in the conversational processing, there is a problem that a client cannot request execution of a plurality of business processes at the same time, and the productivity of the business processes cannot be increased. According to the present invention, in order to solve these problems, the client requests processing to a post office, which is a processing device that relays mail by processing request mail, and the post office requests execution to the corresponding server by processing execution request mail. The results are returned by e-mail, aiming to unify and standardize the operability across OS and language differences, and reduce the system operation load by eliminating the need for environmental information defined between conventional systems. I have.
