Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transaction processing device of an online system for exchanging data between a terminal and a host computer via a communication line.

[0002]

2. Description of the Related Art A conventional transaction processing device for an online system uses only one transaction processing unit to update a large number of database files with one transaction request.

That is, referring to FIG. 3, a transaction processing device of a conventional online system includes a terminal 101 for making a transaction request via a communication line, a host computer 102 for performing actual processing in response to the transaction request, and this transaction. A parent record part 1 that carries out search or update processing in response to a request and holds summary information related to this transaction request
07, and a plurality of child record units 108 that are logically connected to the first record unit and are searched or updated in response to the transaction request and hold detailed information related to the transaction request. File 106,
The parent record unit 107 and the plurality of child record units 108 in the database file 106 are searched or updated based on the input information 103 from the terminal, and the information extracted from each record unit is used as the output information 104 as the terminal 1
01 and a transaction processing unit 105 for transmitting the data.

FIG. 4 is a flow chart for explaining the operation of the transaction processing device of the conventional online system.

The operation of the conventional transaction processing device of the online system will be described with reference to FIGS. 3 and 4.

First, when the host computer 102 receives the input information 103 for online transaction from the terminal 101, the transaction processing unit 105 is activated (step S101 in FIG. 4). The transaction processing unit 105 accesses the parent record unit 107 and the plurality of child record units 108 in the database file 106 based on the input information from the terminal, and retrieves or updates the information necessary for establishing a transaction ( Figure 4 Step S
102). After this search or update processing is completed, the transaction processing unit 105 combines the information extracted from each record unit to generate output information 104, and transmits this output information 104 to the terminal 101 (step S103 in FIG. 4). .

[0007]

In this conventional transaction processing device of the online system, since only one transaction processing unit processes one transaction request, it is necessary to update a large number of database files. The update process takes a lot of time, and it is impossible to immediately send the output information, which is the result of the transaction request, to the online terminal.

Further, since the response time becomes long after the input information is input until the output information is transmitted, the output information transmitted from the host computer is rejected by the time monitoring control on the terminal side. There was a flaw.

[0009]

A transaction processing device of an online system according to the present invention performs an actual process in response to an online terminal that makes a transaction request via a communication line and the transaction request sent from the terminal. A host computer, a parent record section that performs search or update processing in response to the transaction request, holds summary information related to the transaction request, and is logically connected to the parent record section and responds to the transaction request. A database file having a plurality of child record parts that carry out a search or update process and hold detailed information related to the transaction request, and a search or update process of the parent record part based on input information from the terminal. A first process for searching the child record part;
In response to a parent transaction processing unit that performs the second process of transmitting the information extracted from each of the record units as output information to the terminal after the completion of the first process, and a start instruction from the parent transaction processing unit. It is provided with a plurality of child transaction processing units that perform a search or update process for the corresponding child record unit.

[0010]

The present invention will be described in detail with reference to the drawings.

Referring to FIG. 1, one embodiment of the present invention is
Online terminal 11 for making a transaction request via a communication line
And a host computer 20 that performs actual processing in response to a transaction request sent from a terminal, and a parent record unit 51 that holds summary information related to this transaction request that is searched or updated in response to the transaction request. And a database file 50 having a plurality of child record parts 52 to 54 that are logically connected to the parent record part and are searched or updated according to the trade request and hold detailed information related to the trade request. , A first process of performing a search or update process of a parent record part and a search of a child record part based on input information 21 from the terminal, and output information obtained from each record part after completion of the first process A parent transaction processing unit 31 that performs a second process of transmitting to the terminal as 22 and an activation instruction 41 from the parent transaction processing unit
In response to the request, the corresponding child record portion is searched or updated, and a plurality of child transaction processing portions 32 to 43 are included.

Next, the operation of this embodiment will be described with reference to FIGS.

The host computer 201 which has received the input information 21 from the terminal 11 has the parent transaction processing unit 3
1 is activated (step S1 in FIG. 2). Based on the input information 21, the parent transaction processing unit 31 searches or updates the parent record unit 51 that holds summary information related to transactions in the database file 50. At this time, if only the outline information extracted from the parent record section 51 as the output information 22 is not sufficient, only the necessary part of the plurality of child record sections 52 to 54 is searched to extract the detailed information (step S2 in FIG. 2).

Subsequently, it is determined whether or not the child record portion needs to be updated as a transaction and there is an unprocessed child record portion (step S3 in FIG. 2).

At this time, if there is an unprocessed child record part, the start instruction 41 is given to the child transaction processing part corresponding to the child record part (step S4 in FIG. 2). The parent transaction processing unit 31 combines the information obtained from the parent record unit 51 and the child record units 52 to 54 to generate the output information 22 and transmits it to the terminal 11 (step S6 in FIG. 2).

On the other hand, the child transaction processing unit 32 activated by the activation instruction 41 updates the information to be held in the transaction with respect to the child record unit 52 (step S in FIG. 2).
11). Further, it is determined whether or not there is an unprocessed child record part (step S12 in FIG. 2).

At this time, if there is an unprocessed child record part, the start instruction 42 is given to the child transaction processing part corresponding to the child record part (step S13 in FIG. 2).

The child transaction processing unit 33 activated by the activation instruction 42 updates the information to be held in the transaction with respect to the child record unit 53 (step S1 in FIG. 2).
1). In this way, a plurality of child transaction processing units 32
If the corresponding child record section is a child record section that has not been updated, the steps to 34 are sequentially activated until the update processing is completed. In this embodiment, the child transaction processing unit 34 updates the final child record unit 54 (step S1 in FIG. 2).
1), the transaction processing ends because there is no child record part that has not been updated (step S12 in FIG. 2).

Further, since the transaction is not completed while the child transaction processing units are sequentially activated, the parent record unit 51 or the child record units 52 to 54 are caused by another transaction.
Is inconvenient.

In such a case, an access prohibition flag 51a indicating whether or not processing is being performed may be provided in the parent record section 51.

That is, the parent transaction processing unit 31
When the parent record section 51 is searched or updated, the access prohibition flag 51a is turned on to prevent the parent record section 51 from being accessed by another transaction (step S2 in FIG. 2). Then, when all the unprocessed child record parts do not exist, the access prohibition flag 51a is turned off (step S5 and step S1 in FIG. 2).
4), other transactions can be processed subsequently.

[0022]

As described above, since the transaction processing device of the online system according to the present invention divides one transaction into the parent transaction processing section and the plurality of child transactions to perform processing, a large amount of database files are updated. Even in a transaction that needs to be performed and requires immediate processing, output information can be immediately transmitted to the online terminal because the update processing that requires a long processing time is performed by the plurality of child transaction processing units.

Further, since the transaction processing unit is divided into a plurality of units for transaction processing, the processing time in one trunk processing unit can be shortened and various resources such as database files in the host computer can be released in a short time. It also has the effect of preventing delays in other transactions within the online system.
