Description

[Detailed Description of the Invention] [Summary] A file update verification method for verifying changes in the contents of a file that stores main information, the file contents in the final state of the previous day and the contents of the file before the start of work on the current day. To verify that there are no changes, check the total value of the date/time information at the time of file update recorded in the management ↑a information area provided in each page of the file, the last time of the previous day and the start of work on the day. By comparing with the previous one, accurate verification can be processed in a shorter time.

[Industrial application field]

The present invention relates to a file update verification method that verifies the presence or absence of changes in files storing various types of main information.

For example, the banking system has the user's code number 2.
User information such as name and address, account information such as savings account and time deposit account, and date of transaction.

It has and manages a ledger file that stores major information such as transaction information such as transaction amount.

This ledger file is managed by updating important information on a daily basis, so any errors in the content could cause serious damage to users, so the content is verified through various cross-checks. .

One of these is to verify whether the status of the ledger file at the end of the previous day's work and the contents of the ledger file up until the start of the day's work have been intentionally changed.

Since such verification is performed in a short period of time before the start of work, it is required to process accurate verification in a short period of time.

[Prior art and problems to be solved by the invention] Figure 3 is a system overview diagram of the banking system, Figure 4 is a block diagram explaining the conventional example, and Figure 5 explains the status of the ledger file in the conventional example. Figures are shown for each.

It consists of a ledger file 4 that stores information such as addresses, etc.

Further, FIG. 4 is a diagram showing the operational concept when updating and verifying the contents of the ledger file 4, and is denoted by the symbol ■.

■, ■~■ indicate the processing procedure.

This operational conceptual diagram includes a database management system 5 that has a function for processing the management and operation of the ledger file 4, an application program 6 that calls and executes the database management system 5, and a verification process for the contents of the ledger file 4. It consists of a verification program 7 for execution, an output list 8 for printing out data for verification processing based on the verification program 7, and the like.

The inside of the ledger file 4 used in this system is divided into recording areas in page units (in this example, eight pages P1 to P8) as shown in FIG. 5(A).

Each page P1 to P8 is as shown in FIG. 5(B) (the shaded area in FIG. 5(A) is shown as an example).
- A page control section (a) for recording P8 control information (for example, ID information, etc.) is provided in the first area, and a data section (b) for recording main information regarding the user is provided in the subsequent area. - Furthermore, rAAA J in the data section (bl) is the user code number.

rBBBJ is a user information record section that records user information such as name and address; rBBBJ is an account record section that records account information such as savings accounts and time deposit accounts; Each shows a transaction history record section that records history information.

The verification work that is carried out every day when operating such a system is to check the ledger file 4 of the final work completion status of the previous day.
There is a task of verifying the contents of the ledger file 4 and the contents of the ledger file 4 before the start of the day's work.

This verification is to verify that there is no equivalent change in the status of the ledger file 4 from the previous day's final business end status to the current day's status before the start of business; if there is any change, it means that the change was intentional. This is because it is necessary to investigate its contents.

The operation of this system is based on ■Application program 6.
Database management system 5 by starting CPUI
Call this database management system 5.
In the processing based on

Perform rCCCJ update processing.

■ After performing such processing, the day's business processing is completed, and the verification list of the end status of the day (target file name, data part (total value of contents of bl, for example, total value of balance of user account, etc.) is verified. Run program 7 to tally and take out.

■The next day, before implementing the day's business processing, run the same verification program 7, tally the total value of the contents of the data section (b), ■output the verification list on the output list 8, and change the Verify the presence or absence of .

However, with the conventional verification methods described above, depending on the content (amount of data) of the processed data, the verification work may not be completed within the predetermined time before the start of work, which may hinder subsequent work processing. There was a problem.

[Means for solving problems]

FIG. 1 shows a detailed illustration of the invention.

Figure 1 shows records 5 in a file in units of multiple pages Pi.
Each page Pi has a page control section (al) in a predetermined area and a data section (bl) in another area.

Furthermore, a management area (C) for recording the date and time when the contents of the data section (bl) were updated is newly provided at a fixed position in the page format i1 [copy 1+a).

Further, within the database management system 5, there is a management information accumulating means (unit) 5a having a function of simply adding up the numerical values of the information in the management area (C) of each page Pi;
The management information accumulation means (copy) in the verification program 7 5
A cumulative information verification means (unit) 7a having a function of taking out the total value information accumulated in step a as verification information is provided.

[Effect]

The management information accumulation means calculates the total value of the contents of the management information (updated date/time information) in the page control section of the predetermined area of each page of the ledger file (for example, the date/time recorded at the time of update).
By simply summing the numerical values of the time information), extracting the total value using the cumulative information verification means, and verifying the previous total value and the current total value, accurate verification processing can be performed in a shorter time. It becomes possible to do so.
