Description: TECHNICAL FIELD The present invention relates to a data management system for managing information required for a terminal device to connect to a plurality of host computers via a switching network.

[Conventional technology]

FIG. 3 is a block diagram showing a configuration of a data communication system using a conventional data management system disclosed in Japanese Patent Application Laid-Open No. 63-90262. In FIG. 3, 1 is an XNA host computer (a host computer having the X Network Architecture),
2 is a YNA host computer (host computer with Y Network Architecture), and XNA and YNA are optional Network Archi
Network Architec which is a tecture and XNA, YNA
It does not indicate ture. Reference numeral 3 denotes an exchange network for connecting lines to the host computers 1 and 2 and the terminal device 4. In the terminal device 4, 41 is a CCU (communication control unit) for performing communication control, 42 is a connection information table having an emulator ID (identifier) corresponding to a business name, a host computer address, a logon parameter and a logoff parameter, and 43 is a business name , A menu file having a menu,, a display screen for displaying an operation menu, etc., a connection control program, an XNA emulator for emulating the XNA host computer, a YNA emulator for emulating the YNA host computer, 47 is an emulator selection means for selecting the emulator 461 or 462.

 Next, the operation of this conventional example will be described.

When the terminal device 4 accesses the XNA host computer 1 or the YNA host computer 2, the name of the business process, which is the type of business process placed on the host computer, is loaded from the menu file 43 when the terminal device 4 is started up. It is displayed on the display screen 44 as a task menu. When the operator operating the terminal device 4 selects and operates the job menu 44, the connection control program 45 searches the connection information table 42 and extracts the XNA emulator 461 or the YNA emulator 462 corresponding to the selected job. Then, the emulator 461 or 462 is selected.
Next, the connection control program 45 extracts the host computer address and performs dialing to the exchange network 3. As a result, the terminal device 4 is connected to the line of the host computer 1 or 2. Subsequently, this command is extracted to start a session between the host computer 1 or 2 and the terminal device 4 (hereinafter, this is referred to as logon), and the host computer 1
Or, a log-on command is issued for 2. After that, the business connection command is issued and the business connection is established. As a result, a series of business connection control is completed, the mode is shifted to the business processing mode, and the business processing is started. At the end of the work, the connection control program 45 returns from the work processing mode to the connection control program mode and selects the end, so that the connection control program 45 performs from logoff to disconnection.

In such a processing flow, a block diagram for explaining creation / change of the current connection information table 42 is shown in FIG.
FIG. In FIG. 4, the connection information table 42 has a format in which one transaction is one record. The connection information table 42 uses the connection information table creation / change program 48 to store the business name, emulator ID, host computer address, logon parameter, and logoff parameter, which are parameters on the connection information table 42, for each business.
It is created by a user inputting from a keyboard, and is registered in a recording medium 5 such as a built-in fixed magnetic disk, a floppy disk, or an external fixed magnetic disk.
Also, when the connection information table 42 is changed, the connection information table creation / change program 48 is used to perform an operation from the user's keyboard.

[Problems to be solved by the invention]

The creation and modification of the connection information table 42 in the conventional data management method is performed by using a connection information table creation / change program.
48 is used. However, when registering the contents of the table, the user must know the format understood by the connection control program 45 and must understand what information must be registered specifically. Further, when there is a change in a parameter of a certain business in the connection information table 42, the host computer that operates the business needs to notify the change information to all terminal devices that use the business. It was necessary to reflect the change information that the terminal device also notified on the connection information table 42 using the connection information table creation / change program 48. Further, if the above operation is not performed, there is a disadvantage that the business cannot be used thereafter. In addition, when a new business is added to the connection information table 42, the above operation has to be performed. Furthermore, when a new terminal device is introduced, a business connection information table used by the terminal device
42 has to be obtained from each host computer on which the operation is performed, and there is a disadvantage that it takes a long time to complete the operation.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has a data management device that collectively manages a connection information table for all services used by a terminal device, and a host that performs a desired task operation.
