Abstract

PURPOSE:To prevent a contradiction from being generated in basic data due to the change of a file by providing generation information, to show which basic data of plural basic data files respective records in a job file are prepared with being based on in the respective records. CONSTITUTION:When a basic data file holding means 1 holds basic data files 11 and 12 of plural generations and a generation information deciding means 4 updates a record 30 in a job file 3, the generation in the record 30 is decided based on the generation information in the record 30. A basic data file developing means 5 develops the basic data files 11 and 12 of the generation from the basic data file holding means 1 to a work file 2 and a job file record preparing/updating means 6 updates the record based on the basic data file which is developed from to the work file 2 by the basic data file developing means 5. Thus, the contradiction is prevented from being generated when the basic data files 11 and 12 are changed. Then, the correct updating of the record in the job file can be guaranteed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a file management method, and in particular, a method for creating/updating records in a business file (a file used in actual business) based on a basic data file. This invention relates to a file management method in a computer system in which basic data files are changed.

[Conventional technology]

Conventionally, with this type of file management method, when a basic data file is changed, there is a discrepancy between records that have already been registered (created) in the business file and the new basic data file (new basic data file after the change). There was an event that occurred.

Therefore, in order to avoid such an event, when the basic data file is changed, all records in the business file are re-created based on the new basic data file.

[Problem to be solved by the invention]

In the conventional file management method described above, when the basic data file is changed, a discrepancy occurs between records already registered in the business file and the new basic data file. The disadvantage is that the records in the business file cannot be updated correctly, making the records in the business file unusable.

In addition, in order to solve the above-mentioned drawbacks, it is necessary to recreate all records in the business file based on the new basic data file when changing the basic data file, so additional work is required when changing the basic data file. The disadvantage is that it increases.

In view of the above-mentioned points, an object of the present invention is to properly perform generation management of basic data files so that when the basic data file is changed, there is a gap between records already registered in the business file and the new basic data file. An object of the present invention is to provide a file management method that can prevent the occurrence of inconsistencies and ensure correct updating of records in business files.

[Means to solve the problem]

The file management method of the present invention includes a basic data file holding means that holds basic data files of multiple generations, and when a record in a business file is updated, the record is updated based on the generation information in the record. a generation information determining means for determining whether the generation basic data file has been created based on the generation basic data file; and a basic data file for expanding the generation basic data file determined by the generation information determining means from the basic data file holding means into a work file. It has an expansion means, and a business file record creation/update means for updating the record based on the basic data file expanded into a work file by the basic data file expansion means.

[Effect]

In the file management method of the present invention, the basic data file holding means holds basic data files of a plurality of generations, and when the generation information determining means updates a record in the business file, it updates the record in the business file based on the generation information in the record. determining which generation of basic data file the record was created based on, the basic data file expansion means expanding the basic data file of the generation determined by the generation information determination means from the basic data file holding means into a work file;
The business file record creation/update means updates the record based on the basic data file developed into a work file by the basic data file development means.

(Example〕 Next, the present invention will be explained with reference to the drawings.

FIG. 3 is a diagram for explaining the operation when records in the business file 3 are updated using the new basic data file 11 in the basic data file holding means 1 according to the file management method of this embodiment. It is.

FIGS. 4(a) to (C1) show operations when records in the business file 3 are updated using the old basic data file 12 in the basic data file holding means 1 according to the file management method of this embodiment. FIG.

Next, the operation of the file management system of this embodiment configured as described above will be explained.

First, the operation when a new record is created in the business file 3 by input information to a computer system (an online real-time system etc. can be assumed) including the file management method of this embodiment will be explained ( (See Figure 2).

When a new record is created in the business file 3, processing is always performed based on the latest basic data file in the basic data file holding means 1. Therefore, the new basic data file 11 that has already been developed in the work file 2 (the new basic data file 11 has been developed as the steady state FLi (including the initial state) in the work file 2) is used to File record creation/
A record (record identified by diagonal lines in FIG. 2) is created in the business file 3 by the updating means 6.

In this case, information indicating that the newly created record was created based on the new basic data file 11 ("new" in Figure 2) is added to the generation information 30 in the record when the business file record is created. /Stored by the update means 6.

Subsequently, a new basic data file 11 is created based on input information to the computer system including the file management method of this embodiment.
The operation when a record in the business file 3 created based on is updated (when the record update process is performed using the new basic data file 11 in the basic data archive holding means l) will be explained (Chapter 1). (See Figure 3).

In this case, first, based on the generation information 30 in the record to be updated, the generation information determining means 4 determines that the record has been created based on the new basic data file 11.

Based on this determination, the new basic data file 11 expanded in the work file 2 is used to update the record by the business file record creation/update means 6 (“The record is in the new basic data file”). 11, the basic data file expansion means 5 maintains the state in which the new basic data file 11 is expanded in the work file 2).

Finally, when a record in the business file 3 created based on the old basic data file 12 is updated by input information to the total JX machine system including the file management method of this embodiment (basic data file holding means l The operation in the case where record update processing is performed using the old basic data file 12 in FIG. 4 (al to (see C1)) will be described.

In this case, based on the generation information 30 in the record to be updated, the generation information determining means 4 determines that the record was created based on the old basic data file 12.

Based on this determination, the basic data file expansion means 5 converts the basic data file holding means 1 to the work file 2.
The old basic data file 12 is expanded within (Figure 4 (
al).

Next, the old basic data file 12 expanded into the work file 2 as described above based on the determination by the generation information determination means 4 is used, and the update process of the record is performed by the business file record creation/update means 6. (Fig. 4 t)
(see b+).

When the update process for the record that used the old basic data file 12 is completed, the old basic data file 12 existing in the work file 2 is used as the new basic data file IIT again.
The new basic data file 11 is expanded from the basic data file holding means 1 into the work file 2, and the work file 2 is returned to a steady state (see FIG. 4(C)).

Note that when the basic data file is changed, in addition to the new basic data file 11 and the old basic data file 12, the latest basic data file related to the change is held in the basic data file holding means 1, and the business file 3
Information corresponding to the latest basic data file is added to the information set in the generation information 30 in the record in the file (Furthermore, as the work related to the work file 3 progresses, it is created/created based on the old basic data file 12. When the updated record no longer exists in the business file 3, the old basic data file 12 is deleted).

〔Effect of the invention〕

As explained above, the present invention maintains multiple generations of basic data files in the basic data file holding means, and determines which basic data among the multiple basic data files each record in the business file was created based on. By providing generation information indicating this in each record, it is possible to prevent the occurrence of inconsistencies between records already registered in the business file and the new basic data file due to changes in the basic data file. This has the effect of ensuring that records in business files are updated correctly.
