DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically creating a diagram related to an update item of a file, and in particular, to refer to, update, and create data in order to be aware of the data in a system developed in a processing-oriented manner. The present invention relates to an apparatus for automatically creating a file update item relation diagram for each file.

[0002]

2. Description of the Related Art CASE (Computer Aided Software)
Systems built with development tools such as Engineering) are developed in a data-centric manner with data in mind.

However, in the conventional system development that does not use a development tool such as CASE or the like, it is constructed with a function-oriented processing center.

In this conventional method, it is necessary to visually check the source programs constituting the system one by one and create them manually.

[0005] When a new program is created or a program is modified, the related diagram is updated each time a new program is created or modified.

[0006]

In the above-mentioned conventional method, it is necessary to develop a system using a development tool such as CASE or to manually create a related diagram by visual inspection of a source program at the next system development opportunity. Therefore, there is a problem that improvement in work efficiency and productivity in system development and maintenance is hindered.

[0007] The reason is that there is no tool for managing the program, and the development and maintenance personnel create the program whenever necessary due to lack of business know-how.

Accordingly, the present invention has been made in view of the above problems, and has as its object to refer to, update, and update a source program based on a program execution history file.
To provide an apparatus for automatically creating a file update item relation diagram which eliminates a complicated visual check by automatically representing an accurate relation diagram by adding a file name and a program name to a created data item. It is in.

[0009]

In order to achieve the above object, a file update item relation diagram automatic creation device according to the present invention provides a method for referring, updating, and updating a program execution history file based on a program execution history file.
In addition, a program name and a file name are added to the created data for each data item, and a file update item relation diagram is automatically created.

According to the present invention, a program execution history file storing execution date and time information and a program name is searched based on input processing target date information, and a source library storing a source program with the searched program name is searched. By scanning, each data item is referred to (R),
It is characterized by comprising means for extracting data items classified into update (U) and creation (C) and outputting them to an extraction file, and means for outputting the contents of the extraction file.

[0011]

Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram illustrating a configuration example of an embodiment of the present invention. Referring to FIG. 1, an embodiment of the present invention is an input device 1 such as a keyboard.
And a processing device 2 for extracting data items referred to, updated, and created by a target program, and a printer device 3 for outputting the extracted data items as a related diagram.

The processing device 2 has a program execution history 21
And a source library 22 in which a COBOL source program is stored, and a condition determining device 24 for determining conditions
And an extraction file 23 from which data items matching the conditions are output, and a form creation device 25 for tabulating related figures.

According to a preferred embodiment of the present invention, the program execution history file 21 is read under the condition of the input processing target date range, and the source library 22 is read under the program name satisfying the condition, and is referenced (R). , Updated (U) and created (C) are created in the extraction file 23.

When the last data of the program execution history file 21 is detected, it is outputted from the extraction file 23 to the printer 3.

In the embodiment of the present invention, when a source program is changed due to a specification change, a program bug, or the like, or when a new program is created, an update item relation diagram of the latest file (FIG. 6) reference)
Can be created.

A condition determining device 24 for determining a condition
The form creation device 25 may be realized by a program executed on the information processing device.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; The configuration of an apparatus according to an embodiment of the present invention is the same as that of the embodiment described with reference to FIG.

FIG. 2 is a diagram for explaining a specific example of a data item extraction condition in one embodiment of the present invention. FIG.
The operation of one embodiment of the present invention will be described with reference to FIG.

A processing target date is input from the input device 1.

The processing device 2 searches for a target program from the program execution history file 21 on the condition of the processing target date, reads the COBOL source from the source library 22 by using the program name as a key, and Under the indicated conditions, the data items of the file are extracted and written into the extraction file 23.

Under the conditions shown in FIG. 2, the output (outp
In the (out) mode, all the data item names defined in the file are “created”, and in the input (input) mode, all the data item names that specify the file in the processing procedure are “reference”. Output (I-
In the O) mode, the data item name of the file is "reference" on the sending side of the MOVE instruction or the like, and the data item name of the file is "update" on the receiving side of the MOVE instruction or the like.

When all the program execution history files 21 have been read, the form creation device 25 outputs a related diagram to the printer device 3 based on the extraction file 23.

FIG. 5 is a diagram showing an example of the contents of the extraction file 23 in one embodiment of the present invention. Referring to FIG. 5, in the extraction file 23, a program name, a file name, a data item name, and a CUR category are registered. "CU
In "R", C is "create", U is "update", and R is "reference" (ref).
r) are registered.

FIG. 3 is a diagram showing an example of the contents of a program execution history file in one embodiment of the present invention. FIG. 4 is a diagram showing an example of a source program (COBOL) stored in a source program library.

The operation of the embodiment of the present invention will be described more specifically with reference to FIGS.

Referring to FIG. 3, for example, "199702"
The program executed on the date of "18" is read from the program execution history file 21 to find that the program A is the target program, and the program name is used as a key from the source library 22 as shown in FIG. The COBOL source is read in, and is written to the extraction file 23 shown in FIG.

The program execution history file 21 contains "19
The process is repeated until the target date of 970218 "is no longer present.

After processing the date of "19970218", the extraction file 23 is read and an updated item relation diagram of the file shown in FIG. 6 is output.

FIG. 6 is a diagram showing a data item relation diagram output on a form according to an embodiment of the present invention. The CUR category in the program is displayed and output for each data item such as a product code, a product name, stock, and an amount for the file name.

The condition determination device 24 and the form creation device 2
5 does not necessarily need to be separated, and may be configured as one device.

[0031]

As described above, according to the present invention,
By outputting the flow of data on the form, the transition of the data can be recognized, so that a complicated visual check is not required and an update item related diagram of the file can be automatically created.

The reason is that data inconsistency at the time of failure, program debugging at the time of development and maintenance, and visual confirmation at the time of constructing a new system can be confirmed.
