In the above-mentioned conventional technology, only one business processing program can be started for each startup code. Therefore,
When a functional expansion of a business processing program occurs that changes the data storage structure of a database file, it is necessary to migrate and create all database files at once. If the amount of file data is small, it is possible to migrate and create all files at once on a holiday when normal business is not in progress, but if the amount of file data is large, consideration must be given to the fact that switching will take a considerable amount of time. The problem was that some normal operations (update-related operations) had to be stopped to perform the switchover.

The purpose of the present invention is to migrate and create database files in stages as the functions of business processing programs are expanded, so that business processing programs can be started at each function expansion level, and switching operations can be performed without stopping normal business operations. It is to do so.

[Means for solving problems]

The above purpose is to create a terminal table file that can store the input screen table that defines the display information of the input screen for each function expansion level, and a terminal attribute file that can set the attribute information of the terminal control device in both the terminal control device and the computer center. A table, a business processing program code table that can start a business processing program for each startup code and function expansion level, and a program file that can store the business processing program entity are provided, and the corresponding input screen table is searched from the terminal table file. an input screen display processing unit that displays on a display screen device;
An input information transmission processing section that sends the input information from the displayed input screen to the computer center, a business processing startup processing section that starts the corresponding business processing program from the transmitted input information, and a This is achieved by providing an attribute information transmission processing unit that transmits the attribute information of the terminal attribute table for each terminal control device, and an attribute information reception processing unit that sets the transmitted attribute information in the terminal attribute table of the terminal control device. Ru.

[Effect]

Search the input screen table corresponding to the code from the terminal table file. In order to make the retrieved input screen table displayable, the items are divided into input item units and displayed on the display screen device.

The input information transmission processing unit forms the startup code and input items into a message format based on an input instruction for each input item and an input instruction to send from an external source such as an operator, and further adds a function expansion level number to the message. and send it to the computer center.

The business processing startup processing unit converts the startup code and program code that uniquely defines the business processing program called the business processing program code table set in the computer center from the startup code and function expansion level number of the transmitted message. The corresponding program code is obtained from the table set for each function expansion level, and the business processing program is started from that code.

The attribute information transmission processing unit forms the attribute information of the terminal attribute table set in the computer center into a message format, and transmits it to all terminal control devices connected to the computer center at the time of online startup every day. .

The attribute information reception processing section sets the transmitted attribute information in a terminal attribute table existing in the terminal control device.
