Abstract

PROBLEM TO BE SOLVED: To actualize a system which does not decrease the efficiency of transaction processes even if each transaction program makes a request to update common information frequently. SOLUTION: Data from a terminal 31 are handed over to a payment transaction management program 41, a money reception transaction management program 42, or a transfer transaction management program 43. Each transaction management program sends a request to update a sifting information file 54 according to the inputted data. The update request is accepted by a sifting updated data gathering process part 51 of a sifting information process part 50. The process part 51 temporarily stores the accepted update request in a sifting updated data gathering area 52. A sifting updated data reflecting process part 53 of the process part 50 takes out update requests, stored in the areas 51, in sequence and updates the data in the sifting information file 54 at the update requests.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a common information updating method applied to a system in which a plurality of business programs update data in a common data area.

[0002]

2. Description of the Related Art In a system in which a plurality of business programs access one data file, a design has been made in consideration of occurrence of conflict when updating data in the file. For example, when a plurality of business programs generate a request to update the same data area at the same time, exclusive control is performed to arbitrate the request and allow only one business program to be updated.

An update request other than a business program permitted to be updated is waited for. Then, in a system in which data is frequently updated, an update request is frequently waited for, and the processing efficiency of the business program is reduced. Therefore, a method has been proposed in which common information can be updated without performing exclusive control to make another program wait.

For example, in Japanese Patent Application Laid-Open No. 61-151755, each program inputs an update request to a FIFO buffer, and a batch file update program sequentially retrieves the update requests in the FIFO buffer to perform a process of updating common information. The method of performing is described. According to such a scheme,
Each program that issues an update request does not wait until the processing based on the update request of another program ends.

[0005]

However, such a system requires arbitration control for inputting an update request to a FIFO buffer when update requests from each program conflict. Incorrect arbitration may cause deadlock and the like. Therefore, a complicated mechanism for arbitration is required, and the processing efficiency of each program is reduced by such complicated control.

Therefore, the present invention provides a simple method
It is an object of the present invention to prevent the efficiency of business processing from lowering even if a request for updating common information frequently occurs from each business program.

[0007]

According to the common information updating method of the present invention, an update data collecting means for receiving a request for updating common information from each business processing unit and storing the received request in a buffer area, and an update request in the buffer area. Update data reflecting means for reading and updating the common information in response to the read update request. According to such a configuration, each task processing unit can perform another process immediately upon receiving the update request.

Further, the update data collection means and the update data reflection means perform processing asynchronously. Therefore, the update data collecting means can store the update request in the buffer area irrespective of the operation of the update data reflecting means, and as a result, can promptly process the update request from each business processing unit. .

[0009] The update data reflecting means may be configured to read the update request in the buffer area regardless of the input order of the update request to the buffer area.

The common information is, for example, scrutiny information in a banking business, and the plurality of business processing units are a payout business processing program, a deposit business processing program, and a transfer business processing program. The withdrawal business processing program, deposit business processing program, and transfer business processing program need to update the scrutiny information, but it is not necessary to refer to the updated scrutiny information. There is no problem to go.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a common information updating method according to the present invention. In the system shown in FIG. 1, each of the common information update request processing units 11 to 13
Sends an update request for updating the information in the common information file 6 as needed during the predetermined processing. The update request from each of the common information update request processing units 11 to 13 is
It is received by the common information update data collection processing unit 3 in the common information update processing unit 2. The common information update data collection processing unit 3 temporarily stores the received update request in the common information update data collection area 4.

The common information update data reflection processing unit 5 in the common information update processing unit 2 sequentially retrieves the update requests stored in the common information update data collection area 4 and stores the update requests in the common information file 6 in response to the update requests. Update data.
Here, the common information update data collection processing unit 3 stores the update request in the common information update data collection area 4, and the common information update data reflection processing unit 5 is stored in the common information update data collection area 4. It is executed asynchronously with the process of extracting the update request. That is, the common information update data collection processing unit 3 immediately receives update requests from the common information update request processing units 11 to 13 irrespective of the processing of the common information update data reflection processing unit 5.

Therefore, even if an update request is frequently generated temporarily, the data stored in the common information update data collection area 4 only temporarily increases, and the common information update request processing units 11 to 13 The processing efficiency does not decrease. A system in which the equivalent of the common information update data collection processing unit 3 and the common information update data collection area 4 is realized by a FIFO buffer is disclosed in Japanese Patent Application Laid-Open No. 61-151755.
This is a system described in Japanese Unexamined Patent Application Publication No. 2000-205,878. In such a system, when update requests from the common information update request processors 11 to 13 occur simultaneously, arbitration for input to the FIFO buffer is required.

However, in the system shown in FIG. 1, when the update requests from the common information update request processing units 11 to 13 occur simultaneously, the common information update data collection processing unit 3
Receives the update requests sequentially and stores them in the common information update data collection area 4. Therefore, each of the common information update request processing units 11 to 13 does not have to wait until the update processing is completed, and does not require a complicated mechanism for exclusively processing the update request.

FIG. 2 is a system configuration diagram showing an example in a case where the common information updating method shown in FIG. 1 is applied to a specific task. Here, a scrutiny process in the banking system 100 is taken as an example. The scrutiny process is a process in which after the operation is completed, the transaction amount of each day by each terminal is totaled and collated with, for example, information held by a higher system. Therefore,
The amount processed (withdrawn, paid in, or transferred) by each terminal is stored as detailed examination information. For example, when the withdrawal process is performed, the withdrawal information in the scrutiny information is updated, when the deposit process is performed, the deposit information in the scrutiny information is updated, and when the transfer process is performed, the withdrawal information in the scrutiny information is updated. Money information is updated. Then, after all the updating processes are completed, the difference between the payment information and the payment information is calculated, and the inspection information of the day is created.

In the system shown in FIG. 2, data from the terminal 31 is passed to the payment management program 41, the payment management program 42, or the transfer management program 43. The dispensing business management program 41, the deposit business management program 42, or the transfer business management program 43 issues a request for updating the close-up information file 54 based on the input data. The update request is received by the inspection update data collection processing unit 51 in the inspection information processing unit 50. The scrutiny update data collection processing unit 51 temporarily stores the received update request in the scrutiny update data collection area 52.

A scrutinized update data reflection processing unit 53 in the scrutinized information processing unit 50 sequentially retrieves update requests stored in the scrutinized update data collection area 52 and updates data in the scrutinized information file 54 in response to the update request. I do. Here, the inspection update data collection processing unit 51 stores the update request in the inspection update data collection area 52, and the inspection update data reflection processing unit 53 extracts the update request stored in the inspection update data collection area 52. It is executed asynchronously with the processing. That is, the inspection update data collection processing unit 51
Regardless of the processing of the inspection update data reflection processing unit 53, the dispensing business management program 41 and the deposit business management program 42
Alternatively, an update request from the transfer operation management program 43 is immediately received.

The inspection update data collection processing unit 51 and the inspection update data reflection processing unit 53 are realized by, for example, a program, and the inspection update data collection area 52 is realized by a memory in the computer system. Also, FIG.
Although only one terminal 31 is shown, there are actually many terminals.

Next, the operation will be described in more detail. The operator performs various banking operations using each terminal, and each terminal is connected to the banking system 100. When the operator performs the dispensing process, the dispensing operation management program 41 in the banking system 100 issues an update request of the scrutiny information in accordance with the dispensing process. Further, when the operator performs the deposit processing, the deposit business management program 42 in the banking system 100 issues an update request of the scrutiny information in accordance with the deposit processing. Then, when the operator performs the transfer processing, the transfer business management program 43 in the banking business system 100 issues a request for updating the scrutiny information in accordance with the transfer processing.

Upon detecting an update request from the withdrawal business management program 41, the deposit business management program 42, or the transfer business management program 43, the scrutinization update data collection processing unit 51 accepts the request and issues a request for the scrutiny update data collection area. 52. When a plurality of update requests are detected at the same time, the requests are accepted one by one. Therefore, the business program which has issued a request to be accepted later may have a slight wait until the request is accepted. This is much shorter than the case where the system is configured to wait until the data update of the detailed examination information file 54 is completed.

When the inspection update data reflection processing unit 53 detects that there is an update request in the inspection update data collection area 52, the inspection information file 54 is sent in response to the update request.
Update the corresponding data of. Inspection update data collection area 5
When there are a plurality of update requests in the second, the detailed update data reflection processing unit 53 sequentially processes the update requests. The processing order is the input order to the detailed update data collection area 52. It may or may not be. Since each update process for the close-up information file 54 only needs to be completed at the end of the business on that day, it is not particularly necessary to execute the update processes in the order of the update requests.

That is, the area 52 for collecting the inspection and update data
Is a region of a predetermined size, and the inspection update data collection processing unit 51 generally uses the region cyclically, but the inspection update data reflection processing unit 53 It is not necessary to process update requests in the order of input. Therefore, the inspection update data reflection processing unit 53
Can read an update request in the inspection update data collection area 52 by any convenient reading method in the reflection process. Conversely, the inspection update data collection processing unit 5
1 simply stores the received update request in the free area of the inspection update data collection area 52 without any consideration of the processing on the read side of the update request.

As described above, in this embodiment, the banking business system 100 is configured so that a request for updating the scrutiny information file 54 from each business program is accepted by the scrutiny update data collection processing unit 51, and the scrutiny update The data collection processing unit 51 accepts the update request and temporarily stores the update request in the detailed examination update data collection area 52. At this stage, each business program is released from the update request processing, and can immediately start another processing. That is, the processing efficiency of each business program does not decrease.

Further, the inspection update data reflection processing unit 53
The process of updating the scrutinization information file 54 can be performed asynchronously with the request reception process of the scrutiny update data collection processing unit 51. This is because in the process related to the scrutiny, each business program only needs to update the scrutiny information file 54 and does not need to refer to the updated contents of the scrutiny information file 54.

That is, according to the present invention, the update request source is
This is particularly effective in a system in which it is necessary to update the common information but does not need to refer to the common information.

[0026]

As described above, according to the present invention, a common information update method is provided in which an update data collecting means for receiving a common information update request from each business processing unit and storing the same in a buffer area, And an update data reflection unit that reads out the update request and updates the common information in response to the read update request. Even if it occurs, it is possible to prevent the efficiency of business processing from being reduced.
