The operation of the above configuration will be described below.
FIG. 8 is a sequence diagram showing the interaction between the devices in the user support system 20. The figure shows the interaction when the A user refers to and updates the account information, and the copy data of the A user does not exist in the user support apparatus X100a. The A user portable terminal 700a requests the user support apparatus X100a to refer to account information (S2). Since there is no copy data of the A user, the user support apparatus X100a requests the correspondence management apparatus 200 to acquire master data (S4).

  The correspondence management apparatus 200 acquires master data from the order management apparatus 300 (S6), and transmits the master data to the user support apparatus X 100a (S8). At the same time, the correspondence management apparatus 200 updates the correspondence information for associating the master data of the A user with the copy data (S10). The user support device X100a transmits master data to the A user portable terminal 700a (S12) and generates copy data of the A user (S14). When the A user portable terminal 700a requests the user support apparatus X100a to refer to the account information again (S16), the user support apparatus X100a transmits the copy data of the A user to the A user portable terminal 700a (S18).

  Subsequently, the A user portable terminal 700a requests the user support apparatus X100a to update the account information (S20). The user support apparatus X100a updates the copy data of the A user according to the update request data (S22), and maintains the update process in an unconfirmed state. The user support apparatus X100a transmits update data of the copy data to the correspondence management apparatus 200 (S24). The correspondence management apparatus 200 transmits the received update data to the order management apparatus 300 (S26).

  Subsequently, the order management apparatus 300 updates the master data with the update data (S30), and maintains the update process in an unconfirmed state. The order management apparatus 300 notifies the correspondence management apparatus 200 of the successful update (S32). The correspondence management device 200 determines the update of the copy data in the user support device X100a and the update of the master data in the order management device 300 (S34). The user support apparatus X100a notifies the A user portable terminal 700a of the completion of updating the account information (S36).

  FIG. 9 is also a sequence diagram illustrating the interaction between the devices in the user support system 20. This figure shows an interaction in which the update of the master data of the A user is propagated to the copy data when the copy data of the A user exists in the user support device X100a and the user support device Y100b. The order management apparatus 300 updates the master data of the A user with the update data received from the external apparatus (S42), and maintains the update process in an unconfirmed state. The order management device 300 transmits the update data of the master data to the correspondence management device 200 (S44).

  The correspondence management device 200 transmits the received update data to the user support device X100a (S46). The user support apparatus X100a updates the copy data of the A user with the update data (S48), and maintains the update process in an unconfirmed state. Furthermore, the correspondence management apparatus 200 transmits the received update data to the user support apparatus Y100b (S50). The user support apparatus Y100b updates the copy data of the A user with the update data (S52), and maintains the update process in an unconfirmed state. The correspondence management apparatus 200 determines the update of the master data in the order management apparatus 300 and the update of the copy data in the user support apparatus X100a and the user support apparatus Y100b (S54).

  According to the user support system 20 described above, each of the user support apparatuses 100 that first accepts user access holds copy data of account information. When the master data is updated, the update is reflected in the copy data, and the data is synchronized. Thereby, the account information reference request transmitted from the user terminal 700 can be closed to the user support apparatus 100 and can be distributed and processed by the plurality of user support apparatuses 100. In other words, the master data reference count for the order management apparatus 300 is reduced, and the response time for the reference request is improved. In general, the number of account information references is overwhelmingly larger than the number of updates. According to the configuration of the user support system 20, the reference traffic and the update traffic can be separated, and quick reference and quick update can be realized.

  Further, according to the user support system 20, since no access to the order management apparatus 300 occurs when a reference request is made from the user, a transmission delay time for accessing the order management apparatus 300 does not occur, and the user reference request Response time can be improved.

  Furthermore, according to the user support system 20, the correspondence relationship between the master data and the copy data is centrally managed in the correspondence management apparatus 200. As a result, each user support apparatus 100 only needs to hold and process the copy data of the user for which the own apparatus accepts access, and the amount of hardware resources and the processing load of each user support apparatus 100 can be reduced. Further, in response to a reference request from the user terminal 700, copy data and correspondence information of the reference request user are generated. As a result, the amount of hardware resources and the processing load of the user support apparatus 100 and the correspondence management apparatus 200 can be reduced as compared with the case where copy data and correspondence information of all users are always held.

  Furthermore, according to the user support system 20, the copy data of the user support apparatus 100 is always held in the main memory of the user support apparatus 100. On the other hand, since the master data is held in the hard disk of the order management apparatus 300, the copy data can be accessed at a higher speed than the master data, and the response time for the user's reference request can be improved.

  Furthermore, according to the user support system 20, when the copy data is updated, the update is reflected in the master data, and the data is synchronized. In addition, it is possible to maintain the consistency of the update transaction of master data and copy data. Thereby, it is possible to prevent the user from referring to copy data that has not been updated after the update of the master data has been confirmed, that is, to reduce user convenience due to data inconsistency between master data and copy data.

(Second Embodiment)
In the securities company system 10, a message for notifying the transaction status of each of a plurality of stock issues is transmitted from an external market news report system as needed. Since there are a large number of stock issues and the number of stock transactions is enormous, the number of messages sent from the market news reporting system also becomes enormous. When a huge number of messages are transmitted in this way, some messages may be lost on the network. If the message disappears, the user cannot refer to the correct transaction state of the stock brand, for example, the stock price, and the convenience of the user is reduced.

As a result, the stock information of the main telegram is stored in the main storage unit 402. Further, the stock information of the primary message is also stored in the secondary storage unit 502 via the primary storage synchronization unit 410 and the secondary storage synchronization unit 510. Also, in this case, the acquisition unit 602 acquires the next main system message from the main system transfer unit 406, acquires the next sub system message from the sub system transfer unit 506, and the determination unit 604 determines the next main system message. Matching with the next subsystem message and the context are determined in the next determination.

  Secondly, a case will be described in which it is determined that the main system message and the sub system message do not match and the transmission time of the main system message is before the transmission time of the sub system message. In this case, the instruction unit 606 transmits a storage instruction for the main system message to the main system storage control unit 408. As a result, the stock information of the main telegram is stored in the main storage unit 402. Further, the stock information of the primary message is also stored in the secondary storage unit 502 via the primary storage synchronization unit 410 and the secondary storage synchronization unit 510. Also, in this case, the acquisition unit 602 acquires the next main system message from the main system transfer unit 406, and the determination unit 604 matches the next main system message with the sub system message used in the previous determination, and before and after. The relationship is determined in the next determination.

  Third, a case will be described in which it is determined that the main system message and the sub system message do not match and the transmission time of the main system message is later than the transmission time of the sub system message. In this case, the instruction unit 606 transmits a storage instruction for the sub system message to the sub system storage control unit 508. As a result, the stock information of this sub system telegram is stored in the sub system storage unit 502. Furthermore, the stock information of the sub system telegram is also stored in the main system storage unit 402 via the sub system storage synchronization unit 510 and the main system storage synchronization unit 410.

Are determined in the next determination.

  A modification in the above-described third case will be described. In this modification, the instruction unit 606 transmits a sub system message and a storage instruction for the sub system message to the main system storage control unit 408. As a result, the stock information of the sub system telegram is stored in the main system storage unit 402. Furthermore, the stock information of the sub system telegram is also stored in the sub system storage unit 502 via the main system memory synchronization unit 410 and the sub system storage synchronization unit 510. Also in this modified example, the acquisition unit 602 acquires the next sub system message from the sub system transfer unit 506, and the determination unit 604 matches the match between the main system message used in the previous determination and the next sub system message. The context is determined in the next determination.

  FIG. 14 is a flowchart for explaining the flow of processing in the stock information comparison apparatus 600. When receiving the main system message transmitted from the main system transfer unit 406 (S62), the acquisition unit 602 acquires the sub system message from the sub system transfer unit 506 (S64). The determination unit 604 determines the match and the context of the main system message and the sub system message (hereinafter also referred to as “main / sub message”). When it is determined that the primary and secondary electronic texts match (Y in S66), the instruction unit 606 transmits a primary electronic message storage instruction to the primary storage control unit 408 (S68), and the stock information comparison apparatus 600 performs processing. Exit.

  When the primary message does not match (N in S66) and it is determined that the transmission time of the primary message is before the transmission time of the secondary message (Y in S70), the instruction unit 606 displays the primary message. An instruction to store a normal message is transmitted to the storage control unit 408 (S72). The acquisition unit 602 acquires the next main system message from the main system transfer unit 406 (S74). Thereafter, returning to the processing of S66, the determination unit 604 determines the coincidence and context of the next main message and the sub message used in the previous determination processing.

  When the primary message does not match (N in S66) and it is determined that the transmission time of the primary message is later than the transmission time of the secondary message (N in S70), the instruction unit 606 displays the secondary message. An instruction to store the sub system telegram is transmitted to the storage control unit 508 (S76). Thereafter, the processing returns to S604, the acquisition unit 602 acquires the next sub system message from the sub system transfer unit 506, and the determination unit 604 matches the primary system message used in the previous determination process with the next sub system message. And determine the context.

Thereby, when the primary stock information management device 400 enters a predetermined abnormal state, the user support device 100 can access the secondary storage unit 502 immediately after switching to the secondary stock information management device 500. In other words, the stock information can be provided to the user support device 100 in a shorter time than when the stock information is stored in the hard disk.

  Furthermore, according to the stock information management system 30, when the transmission time of the main system message is before the transmission time of the sub system message, in other words, when the sub system message has disappeared, the main system message is stored in the storage device. It is possible to compensate for the disappearance of the sub-system telegram by memorizing it. Also, when the transmission time of the main system message is later than the transmission time of the sub system message, in other words, when the main system message has disappeared, the sub system message is stored in the storage device so that the main system message disappears. Can be compensated. Thereby, the user's convenience fall by the loss | disappearance of a stock information message | telegram can be prevented.

  Furthermore, according to the stock information management system 30, when the transmission time of the primary message is before the transmission time of the secondary message, the next determination uses the secondary message used in the next determination and the previous determination. System telegrams are subject to judgment. Further, when the transmission time of the main system message is later than the transmission time of the sub system message, in the next determination, the main system message used in the previous determination and the next sub system message are determined. As a result, it is possible to determine a main system message and a sub system message that are highly likely to have the same transmission time, and efficiently detect the disappearance of the stock information message.
