Abstract

PURPOSE:To improve the productivity at the time of generating a computer work system by processing plural keyed files by one piece of program. CONSTITUTION:With regard to all files to be used in a file information generating program 11, information of a file name, a key position, a key size, and a record size is registered as file information. In an item defined information generating program 12 of a file, the contents of a record of a name, a size, and an attribute are registered by an item unit as item information in each file unit. In a file updating program 13, a file is updated, the file to be updated is instructed from a screen, and by file information and item information of its file, real data is edited and outputted to the screen and its screen data is changed, and a changed result is written in an updating file. Accordingly, plural files can be processed by one piece of program. In such a way, the number of programs decreases, then the productivity can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyed data file update method in a computer system, and particularly to a data file update method that is processed by one program.

[Conventional technology]

In conventional computer systems, when updating keyed data files, a program is created for each file. In each update program, data items are edited for easy viewing and displayed on a screen or in a form.

For file update processing, it generally has the functions of specifying the key of the data and referring to, changing, and deleting the data.

[Problem to be solved by the invention]

In the conventional file update method described above, a program is created for each file, so the number of programs is large.
Poor productivity.

SUMMARY OF THE INVENTION An object of the present invention is to provide a data file update method that can process multiple files with a single program and that makes screens or forms as easy to view as possible.

[Means to solve the problem]

In the data file update method according to the present invention, information such as file name, key position, key size, and record size is registered as file information for all files to be used, and record contents for each file are updated item by item. Register the name, size, and attributes as item information,
Update the file, specify the file to be updated from the screen, edit and output the actual data to the screen using the file information and item information of the file, change the screen data, and write the changed results to the update file. .

〔Example〕

Next, an embodiment of the present invention will be described in more detail with reference to the drawings.

FIG. 1 is a functional block diagram of an embodiment of the present invention. In the file information creation program 11, information such as file name, key position, key size, and record size is registered as file information for all files to be used.

In the file item definition information creation program 12,
Register the record contents for each file, and register the name, size, and attributes for each item as item information.

The file update program 13 updates files.

The file to be updated is specified from the screen, and the actual data is edited and output to the screen based on the file information and item information of the file. Change the screen data, write the changed results to an update file, and print it as a list.

FIG. 2 is a diagram showing the contents of definition information. The definition table 21 is a table of key position, key size, and record size information for each file name. That is, it is a table of file names that distinguish files, key positions, key sizes, record lengths, etc. when searching for actual data of the files.

The definition table 22 is item information, including a file name that distinguishes the file, and information on the name, size, and attribute of each item of the file, and is data used when editing actual data. Since the item information defines the items included in the file in the order in which the actual data is arranged, item position information is not required as item information.

FIG. 3 is a flowchart of this embodiment. Step 3
1, the file name to be updated, the key value of the data to be updated,
Enter the update mode (copy registration, change, deletion, reference) and the item name to be changed.

In step 32, the file information and item information file are read using the input file name as a key, and the key position, key size, record size, and item name, position, and size of the file are expanded into memory.

In step 33, the data file is determined using the input file name as a key, and the data is read using the input key value.

In step 34, the data is edited item by item, and the item name and data value are paired in an easy-to-read format and displayed on the screen as shown in FIG. 4 (FIG. 4 46).

In step 35, the part to be changed is changed from the screen.

At this time, since the item name is displayed, the data can be changed very easily.

At step 36, the modified data is written to the file.

In step 37, the data contents before and after the change are listed.

〔Effect of the invention〕

As described above, the present invention has the effect of improving productivity in creating a computer business system by processing a plurality of keyed files using one program.
