FIG. 3B is a diagram illustrating a concept of manufacturing products P21, P22, and P23 from the base material M2. M1 and M2 are base material IDs for identifying types of base materials, and P11 to P13 and P21 to P23 are product IDs for identifying products. As a specific example of this embodiment, as shown in FIGS. 3A and 3B, products P11, P12, and P13 and products P21, P22, and P23 are manufactured from two base materials M1 and M2, respectively. Accordingly, a processing example when the base material stock information database 11a and the product stock information database 11b are updated accordingly will be described.

  The base materials M1 and M2 are base materials whose stock data is managed in the base material stock information database 11a of the stock data processing system 10, and the products P11, P12 and P13 and the products P21, P22 and P23 are in stock. This is a product whose inventory data is managed in the product inventory information database 11b of the data processing system 10.

  FIG. 4A is a diagram illustrating a state in which the data table of the base material inventory information database 11a is updated by manufacturing the product illustrated in FIG. FIG. 4B is a diagram illustrating a state in which the data table of the product inventory information database 11b is updated by manufacturing the product illustrated in FIG. As shown in FIG. 4A, the base material M1 has a 6t (ton) inventory before the products P11 to P13 are manufactured, and changes to a 3t inventory after the products P11 to P13 are manufactured. The base material M2 has an inventory amount of 4 t (tons) before the manufacture of the products P21 to P23, and changes to an inventory amount of 1 t after the manufacture of the products P21 to P23. That is, the amount of change due to the manufacture of both the base materials M1 and M2 is 3t. In this embodiment, there are a plurality of stocks of the base materials M1 and M2, and the base materials M1 and M2 used as shown in FIG. 3 are used up, and the base materials M1 and M2 that are not used are used. The total weight is the stock quantity. Further, in the present embodiment, the case where the base materials M1 and M2 are used up has been described in order to simplify the description of the management of the stock quantity, but this is not limited to this, and trimming is performed when a product is cut from the base materials M1 and M2. Even if there is a surplus part due to the cost, the stock amount (total of the stock of the base material and the product is estimated by estimating the length of the base material using the weight of the trim cost. It is also possible to manage the weight).

  Further, as shown in FIG. 4B, the stock quantities of the products P11, P12, and P13 are 3t, 2t, and 0t, respectively, before the manufacture shown in FIG. 3, and the stock quantities of the products P11, P12, and P13 are shown after the manufacture. The quantities have changed to 4t, 3t and 1t, respectively. Also, as shown in FIG. 4B, the stock quantities of the products P21, P22, and P23 are 4t, 1t, and 2t, respectively, before the manufacture shown in FIG. 3, and the stocks of the products P21, P22, and P23 are shown after the manufacture. The amounts have changed to 5t, 2t and 3t, respectively. That is, all of the products P11 to P13 and the products P21 to P23 have a change amount of 1 t due to the current manufacturing.

When there is a change in inventory data as shown in FIGS. 4A and 4B, the inventory data processing system 10 sends an inventory change message (first message) as shown below, for example, to the data processing system 40. It transmits to the data receiver 20. There are two first messages in this embodiment, and msA and msB are assigned as message IDs, respectively. Each first message includes a plurality of change messages indicating changes in individual base materials and products. Here, ms1 to ms8 are assigned as message IDs for identifying each change message.
Change message included in msA ms1: Base material M1 used for 3t ms2: Base material M2 used for 3t msB: Change message included in msB ms3: Product P11 manufactured for 1t ms4: Product P12 manufactured for 1t ms5: Product P13 Ms6: product P21 was manufactured 1t ms7: product P22 was manufactured 1t ms8: product P23 was manufactured 1t

  The data receiving apparatus 20 performs the following process on the first message of msA and msB described above. FIG. 5 is a flowchart illustrating a processing example of the data reception device 20 according to the first embodiment. As shown in FIG. 5, in step S <b> 1, the first message receiver 22 receives the first message via the network 41. According to a specific example, the first message receiving unit 22 receives, for example, the first message of the msA and stores it in the buffer 21.

  Next, in step S <b> 2, the second message creation unit 23 creates a second message with reference to the first message received from the buffer 21. According to a specific example, the first message receiving unit 22 uses the second message based on ms1: “use 3t of base material M1” and ms2: “use 3t of base material M2” included in the first message of msA. “Delete 3t of base material M1” and “Delete 3t of base material M2” are created. Thereby, in step S3, the second message transmission unit 24 sends the second messages “base material M1 3t deletion” and “base material M2 3t deletion” created by the second message creation unit 23 to the data management device 30. Send. In the above-described embodiment, the second message transmission unit 24 starts the transmission process after the second message creation unit 23 finishes creating the plurality of second messages. When the second message creation unit 23 creates a plurality of second messages, the message transmission unit 24 transmits the created second message each time the second message creation unit 23 creates each second message. May be.

  Next, in step S4, the second message transmission unit 24 determines whether or not the final message has been transmitted. Here, the determination of whether or not the final message has been transmitted is the predetermined number of first messages transmitted and received in one communication between the inventory data processing system 10 and the data processing system 40. Based on this, it is determined whether or not the process of creating and transmitting the second message from the first message determined to be the last message has been completed. According to a specific example, since it is the stage which processed the 1st message of msA, it judges that it is NO in Step S4, and returns to Step S1.

  In the next step S <b> 1, the first message receiver 22 receives the first message of msB and stores it in the buffer 21. The subsequent processing for the first message of msB is the same as the processing of steps S1 to S4 described above, and based on ms3 to ms8 included in the first message of msB, a second message of Ms3 to Ms8 described later. Create For example, the second message creating unit 23 creates the second message “add product P11 to 1t” of Ms3 based on ms3: “product P11 is manufactured by 1t” included in the first message of msB.

  Here, if the second message “add 1t of product P23 added” created based on the change message of ms8 in step S3 is transmitted, the second message transmission unit 24 has processed the final message in step S4 And the process proceeds to step S5. In step S <b> 5, the second message transmission unit 24 transmits an end signal to the data management device 30.

With the above processing, the data reception device 20 transmits the following second message to the data management device 30. The second messages Ms1 to Ms8 shown below correspond to the change messages ms1 to ms8 included in the first messages msA and msB.
Ms1: Delete 3t of base material M1 Ms2: Delete 1t of base material M2 Ms3: Add 1t of product P11 Ms4: Add 1t of product P12 Ms5: Add 1t of product P13 Ms6: Add 1t of product P21 Ms7: 1t of product P22 Add Ms8: Add 1t of product P23

  The data management apparatus 30 performs the following process on the second messages Ms1 to Ms8 described above. FIG. 6 is a flowchart showing a processing example of the data management apparatus 30 in the first embodiment. As shown in FIG. 6, in step S <b> 10, the second message receiving unit 32 receives the second message via the network 42. According to a specific example, the second message receiving unit 32 receives, for example, the second message of Ms1 and stores it in the second message storage unit 33.

  Next, in step S <b> 11, the second message receiver 32 determines whether an end signal has been received via the network 42. If the end signal has not been received (NO in step S11), the process returns to step S10, and the second message receiving unit 32 receives the next second message. If an end signal has been received (YES in step S11), the process proceeds to step S12, and the data update processing unit 34 stores a plurality of first messages stored in the second message storage unit 33 with respect to the memory 31. Update processing according to two messages is performed.

  Next, in step S <b> 13, the data confirmation processing unit 35 performs a process of confirming whether the updated base material and product inventory data stored in the memory 31 is consistent with the data before the update process. . In the data processing system 40 of the present embodiment, since all the second messages of Ms1 to Ms8 created in response to the first messages of related msA and msB are received, the update processing is performed on the memory 31 collectively. In the confirmation process by the data confirmation processing unit 35, it is possible to prevent a situation where it is determined that the consistency of the inventory data is not present. That is, when the inventory data to be managed is a plurality of related data, the related inventory data can be updated together.

[Second Embodiment]
Next, a data processing system according to the second embodiment of the present invention will be described.
The data processing system in the second embodiment has the same configuration as the data processing system 40 in the first embodiment shown in FIGS. 1 and 2, and includes a data receiving device 20 and a data management device 30. 40.

  However, the difference from the data processing system 40 in the first embodiment is a process of creating a second message in the data receiving device 20. That is, the functions of the second message creation unit 23 and the second message transmission unit 24 included in the data reception device 20 are different. For example, the second message transmission unit 24 in the second embodiment sends an end signal to the data management device 30. It does not have a function to send. Hereinafter, the data processing system 40 according to the second embodiment will be described with reference to FIGS. 1 and 2 focusing on differences from the data processing system 40 according to the first embodiment.

  A data processing system 40 according to the second embodiment shown in FIG. 1 receives a stock change message (first message) from the stock data processing system 10 via the network 41 and is managed in the memory 31. And a system for updating product inventory data.

  In addition, the data reception device 20 receives a plurality of first messages via the network 41 and stores the received plurality of first messages in the buffer 21. Further, the data receiving device 20 refers to a plurality of related first messages from the buffer 21 and creates one update instruction message (second message) in which related stock change data included in them is collected to create a network. The data is transmitted to the data management apparatus 30 via 42.

  Further, the data management device 30 updates the stock data of the base material and the product stored in the memory 31 based on the second message received from the data receiving device 20 via the network 42. In the present embodiment, the network 42 is a LAN (local area network).

  Here, the details of the functional configurations of the data receiving device 20 and the data management device 30 will be mainly described with reference to FIG. The second message creating unit 23 collects a plurality of related first messages from the plurality of first messages stored in the buffer 21 and creates one second message. Further, the second message transmission unit 24 transmits the second message created by the second message creation unit 23 to the data management device 30. As described above, the second message transmission unit 24 of the present embodiment does not have a function of transmitting an end signal to the data management device 30. In response to this, the data update processing unit 34 of the data management device 30 performs the update process of the memory 31 by sequentially using the second messages stored in the second message storage unit 33.

  Next, processing of the data receiving device 20 in the second embodiment for the first message of ms1 to ms8 shown in the first embodiment will be described. FIG. 7 is a flowchart illustrating a processing example of the data reception device 20 according to the second embodiment. As shown in FIG. 7, in step S <b> 21, the first message receiver 22 receives the first message via the network 41. According to a specific example, the first message receiving unit 22 receives the first message of ms1, for example, and stores it in the buffer 21.

  Next, the first message receiving unit 22 determines whether or not the final first message has been received. That is, the first message receiving unit 22 determines whether all the first messages of ms 1 to ms 8 have been received and stored in the buffer 21. If it is determined that the final first message has not been received (NO in step S22), the first message receiving unit 22 returns to step S21 and receives the next first message. If it is determined that the final first message has been received (YES in step S22), the first message receiving unit 22 proceeds to step S23.

  Next, in step S23, the second message creation unit 23 refers to all the first messages of ms1 to ms8 received from the buffer 21, and creates a second message by putting together the related first messages. Specifically, the first message receiving unit 22 collects the first messages of ms1 to ms4 and creates a second message. Next, in step S <b> 24, the second message transmission unit 24 transmits a second message in which the first messages of ms <b> 1 to ms <b> 4 created by the second message creation unit 23 are collected to the data management device 30. Next, the second message transmission unit 24 determines whether all the first messages have been processed.

  Here, when it is determined that all the first messages have not been processed (NO in step S25), the process returns to step S23, and the second message creating unit 23 selects the related first message from the remaining first messages. A process of creating a second message by collecting the messages is performed. For example, the second message creation unit 23 creates a second message by putting together the first messages of ms5 to ms8.
