BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic data conversion device for automatically converting data.

[0002]

2. Description of the Related Art Conventionally, when converting the data used by a host into the data used by a personal computer, the attributes of each item of the data to be converted are given as parameters, and commercially available software for conversion is used. I was trying to convert it into usable data.

Also, every time data is linked between the host and the personal computer, a dedicated conversion program is separately created for the host and the personal computer to be linked, and the host data is converted into data usable by the personal computer.

[0004]

Therefore, when using the commercially available software that executes the former conversion, only one conversion program is required, but at the time of execution, layout information (attributes for each item, etc.) is used as a parameter. It was necessary to give it each time, and there was a problem that a setting error for that purpose occurred.

Further, in the case of creating the latter dedicated conversion program, it is necessary to create the conversion programs for the number of systems, and there is a problem that a great number of man-hours are required for development and maintenance management.

[0006] The present invention solves these problems,
The purpose is to combine parts based on the specified data source of the conversion source to automatically generate a conversion program, and the automatically generated conversion program performs data conversion processing to realize automatic data conversion.

[0007]

Means for solving the problem will be described with reference to FIG. In FIG. 1, the definition structure 4
Is a pre-defined attribute of each item of data in the conversion source system.

The program generation unit 33 automatically generates a conversion program 34 in which the parts 31 previously created based on the definition body 4 are combined. The conversion execution unit 35
The automatically generated conversion program 34 is activated, and the conversion program 34 executes data conversion.

Next, the operation will be described. The program generation unit 33 automatically generates a conversion program 34 in which the parts 31 created in advance based on the definition body 4 are combined, and the conversion execution unit 35 executes data conversion by the automatically generated conversion program 34. I am trying.

At this time, the data format of the conversion destination is referred to, and the data is automatically set on the data format. Therefore, the conversion program 3 in which the parts 31 are combined based on the specified data source 4 of the conversion source
4 is automatically generated, and the automatically generated conversion program 34
Performs data conversion processing, and can realize automatic data conversion.
