Description

Technical Field

[0001] Embodiments of the present invention relate to an information processing system, an information processing device, a second information processing device, and a storage medium. Background Art

[0002] In recent years, client-server POS (Point of Sales) systems have become increasingly popular, in which the processing functions and databases of transaction processing are configured in the cloud, and the cash register function in the cloud is called from a terminal such as a tablet to perform cash register business in the store. In such a system, if the cloud cannot be connected due to a communication failure, etc., cash register business may not be able to be performed. As a countermeasure in this case, it is considered to configure a server such as an edge server with the same processing functions and database as the cloud on the store side, and switch the terminal's connection destination to the server in the store, so as to achieve business continuity.

[0003] However, when configuring a server in the store that can perform the same processing as the cloud, it is necessary to synchronize the database data between the cloud and the edge server. The cloud database centrally manages the data of the corresponding store's product master file, and each store only needs to synchronize the data corresponding to each store. In addition, since the number of stores connected to the cloud is more than hundreds of stores, the update request access of hundreds of stores is concentrated on the cloud database every time the data is updated, which will increase the load.

[0089] The output section 113 of the cloud server 1 outputs the data distribution file generated by the file generation section 112 to the storage server 2 to store it in the auxiliary storage device 23 ( S4 ).

[0090] The file acquisition unit 210 of the storage server 2 acquires the data distribution file from the cloud server 1 ( S13 ).

[0091] The storage control unit 211 of the storage server 2 stores the data distribution file in the auxiliary storage device 23 (S14).

[0092] The request processing unit 310 of the edge server 3 outputs a request to the storage server 2 after a certain time has passed since the request regarding the presence or absence of the data distribution file was output (S23).

[0093] The instruction acquisition unit 212 of the storage server 2 acquires the request from the edge server 3 ( S15 ).

[0094] The output unit 213 of the storage server 2 outputs a response to the request from the edge server 3 (S16). Here, it is assumed that the data distribution file of the store associated with the edge server 3 is stored in the storage server 2. In this case, the output unit 213 outputs a response "yes" to the edge server 3.

[0095] The request processing unit 310 of the edge server 3 obtains a response “yes” to the request from the storage server 2 ( S24 ).

[0096] The instruction output unit 314 of the edge server 3 outputs an instruction to output the data distribution file to the storage server 2 ( S25 ).

[0103] The storage control unit 211 of the storage server 2 updates the data distribution file based on the update instruction from the edge server 3 ( S20 ).

[0104] Next, the steps of the processing by the information processing system 100 will be described.

[0105] In addition, in the following description based on the cloud server 1, the cloud server 1 can be understood as the processor 11. In the description based on the storage server 2, the storage server 2 can be understood as the processor 21. In the description based on the edge server 3, the edge server 3 can be understood as the processor 31.

[0106] In addition, the processing steps described below are only examples, and each process can be changed as much as possible. In addition, the processing steps described below can be appropriately omitted, replaced, and added according to the embodiment.

[0107] In the following description, it is assumed that in a store with enterprise code "A" and store code "111", edge server 3 with terminal code "aaa" synchronizes the commodity master file with cloud server 1. Cloud server 1 outputs the data distribution file to storage server 2. Edge server 3 obtains the data distribution file from storage server 2 and updates the commodity master file stored in auxiliary storage device 33.

[0108] The data distribution file creation process by the cloud server 1 is described.

[0109] Figure 4 This is a flowchart showing an example of the procedure of information processing performed by the cloud server 1 according to the embodiment.

[0110] The update determination unit 110 determines whether the product master file stored in the auxiliary storage device 13 is updated (ACT1). In ACT1, for example, the update determination unit 110 determines whether the product master file is updated based on the update event output based on the update of the auxiliary storage device 13. If the update determination unit 110 determines that the product master file is updated (ACT1: Yes), the processing transitions from ACT1 to ACT2. If the update determination unit 110 determines that the product master file is not updated (ACT1: No), the processing of ACT1 is repeated. The update of the product master file includes the update of the product record. The update of the product master file includes the update of at least one record in the product master files of multiple companies and multiple stores managed by the cloud server 1. In addition, the update determination unit 110 can periodically monitor the auxiliary storage device 13 and determine whether the product master file is updated.

[0111] The acquisition unit 111 acquires the updated data from the product master file storage area based on the update of the product master file (ACT 2). In ACT 2, for example, the acquisition unit 111 acquires the updated product record. The acquisition unit 111 may acquire the product master file of the store including the updated product record. In addition, the acquisition unit 111 may acquire the updated data every time the product master file is updated, or may acquire the updated data at a predetermined time interval. The acquisition unit 111 may acquire all the updated data, or may acquire only the latest data for each record.

[0112] The file creation unit 112 creates a data distribution file (ACT3) based on the acquired update data. In ACT3, for example, the file creation unit 112 creates a data distribution file for each enterprise, each store, or each edge server based on the identification information of the update data. For example, it is assumed that the commodity master file associated with the edge server 3 with the terminal code "aaa" has been updated. In this case, the file creation unit 112 creates a data distribution file associated with the edge server 3 with the terminal code "aaa". The data distribution file associated with the edge server 3 with the terminal code "aaa" is included in the data distribution file of the store with the store code "111". The file creation unit 112 can create a data distribution file associated with each store.

[0113] The output unit 113 outputs the data distribution file to the storage server 2 to be stored in the auxiliary storage device 23 (ACT 4). In ACT 4, for example, the output unit 113 outputs the data distribution file to the storage server 2. The storage server 2 saves the data distribution file in a corresponding area of ​​the auxiliary storage device 23 based on the identification information.

[0114] The processing related to the data distribution file performed by the storage server 2 will be described.

[0115] Figure 5 This is a flowchart showing an example of the procedure of information processing performed by the storage server 2 according to the embodiment.

[0116] The file acquisition unit 210 acquires the data distribution file output from the cloud server 1 (ACT 11 ).

[0117] The storage control unit 211 stores the data distribution file in the auxiliary storage device 23 (ACT12). In ACT12, for example, the storage control unit 211 stores the data distribution file in the corresponding area based on the identification information of the data distribution file. For example, if the data distribution file has an enterprise code "A", a store code "111", and a terminal code "aaa", the storage control unit 211 saves the data distribution file in the area assigned to the edge server 3 with the enterprise code "A", the store code "111", and the terminal code "aaa". The storage control unit 211 stores the data distribution file in the auxiliary storage device 23 in association with each enterprise, each store, or each edge server.

[0118] The instruction acquisition unit 212 determines whether a request regarding the existence of a data distribution file is obtained from the edge server 3 (ACT 13). When the instruction acquisition unit 212 determines that a request is obtained (ACT 13: Yes), the process transitions from ACT 13 to ACT 14. When the instruction acquisition unit 212 determines that a request is not obtained (ACT 13: No), the process of ACT 13 is repeated.

[0119] The instruction acquisition unit 212 determines whether there is a store data distribution file associated with the edge server 3 (ACT 14). In ACT 14, for example, the instruction acquisition unit 212 determines whether there is a data distribution file in a designated area associated with the edge server 3 based on at least one of the enterprise code, the store code, and the terminal code of the edge server 3 included in the request. The designated area associated with the edge server 3 may be an area allocated to the edge server 3 or an area allocated to a store associated with the edge server 3.

[0120] The output unit 213 outputs a response to the request from the edge server 3 (ACT 15). In ACT 15, for example, the output unit 213 outputs a response regarding the presence or absence of a data distribution file of a store associated with the edge server 3. If the instruction acquisition unit 212 determines in ACT 14 that a data distribution file exists, the output unit 213 outputs a response "yes" indicating that the data distribution file exists. If the instruction acquisition unit 212 determines in ACT 14 that a data distribution file does not exist, the output unit 213 outputs a response "no" indicating that the data distribution file does not exist.

[0121] The instruction acquisition unit 212 determines whether an output instruction is obtained from the edge server 3 (ACT 16). The edge server 3 outputs an output instruction when the data distribution file exists in the designated area assigned to the store associated with the edge server 3 based on the response to the request output by the output unit 213. When the output instruction is obtained by the instruction acquisition unit 212 (ACT 16: Yes), the process transitions from ACT 16 to ACT 17. In the case where the output instruction is not obtained by the instruction acquisition unit 212 (ACT 16: No), the process of ACT 16 is repeated. In addition, if the request related to the presence or absence of the data distribution file from the edge server 3 includes an output instruction, the instruction acquisition unit 212 can determine that there is an output instruction based on the request. In this case, the process of ACT 16 can be omitted.

[0122] The output unit 213 outputs the data distribution file to the edge server 3 (ACT 17). In ACT 17, for example, the output unit 213 outputs the data distribution file associated with the edge server 3 to the edge server 3. The output unit 213 may output all the data distribution files associated with the edge server 3 to the edge server 3, or may output only the latest data distribution file associated with the edge server 3 to the edge server 3.

[0123] The instruction acquisition unit 212 determines whether an update instruction is acquired from the edge server 3 (ACT 18). If an update instruction is acquired by the instruction acquisition unit 212 (ACT 18: Yes), the process transitions from ACT 18 to ACT 19. If an update instruction is not acquired by the instruction acquisition unit 212 (ACT 18: No), the process of ACT 18 is repeated.

[0124] The storage control unit 211 updates the data distribution file based on the update instruction from the edge server 3 (ACT 19). In ACT 19, for example, when the storage control unit 211 obtains a move instruction from the edge server 3, the data distribution file associated with the edge server 3 is moved from the distribution file directory to the synchronization completion directory. When a deletion instruction is obtained from the edge server 3, the storage control unit 211 deletes the data distribution file associated with the edge server 3. The storage control unit 211 can delete the data distribution file associated with the edge server 3 from the distribution file directory, or delete the data distribution file associated with the edge server 3 from the auxiliary storage device 23. The data distribution file associated with the edge server 3 corresponds to the data distribution file output to the edge server 3. Based on this, the storage server 2 can determine whether there is a data distribution file that should be output to the edge server 3.

[0125] The process of synchronizing with the commodity master file in the edge server 3 will be described.

[0126] Figure 6 This is a flowchart showing an example of the procedure of information processing by the edge server 3 according to the embodiment.

[0127] The request processing unit 310 outputs a request regarding the presence or absence of a data distribution file to the storage server 2 (ACT 21). In ACT 21, for example, the request processing unit 310 outputs a request regarding the presence or absence of a data distribution file associated with the edge server 3 at predetermined intervals.

[0128] The determination unit 311 determines whether there is a data distribution file associated with the edge server 3 (ACT 22). In ACT 22, for example, the determination unit 311 obtains a response from the storage server 2 to the request output by the request processing unit 310. The determination unit 311 determines whether there is a data distribution file associated with the edge server 3 based on the response from the storage server 2. If the determination unit 311 determines that there is a data distribution file associated with the edge server 3 (ACT 22: Yes), the process transitions from ACT 22 to ACT 23. If the determination unit 311 determines that there is no data distribution file associated with the edge server 3 (ACT 22: No), the process of ACT 22 is repeated.

[0129] The acquisition unit 312 acquires the data distribution file associated with the edge server 3 from the storage server 2 (ACT 23). In ACT 23, for example, the acquisition unit 312 acquires the data distribution file of the area assigned to the edge server 3 with the terminal code "aaa" from the storage server 2. In one example, the acquisition unit 312 acquires all the data distribution files associated with the edge server 3. In another example, the acquisition unit 312 acquires the latest data distribution file associated with the edge server 3.

[0130] The storage control unit 313 updates the commodity master file stored in the auxiliary storage device 33 based on the acquired data distribution file (ACT 24). In ACT 24, for example, the storage control unit 313 causes the auxiliary storage device 33 to store the data distribution file. When a plurality of data distribution files are acquired by the acquisition unit 312, the storage control unit 313 stores the latest data distribution file in the auxiliary storage device 33 based on the time stamp or the like included in the data distribution file. When the latest data distribution file is acquired by the acquisition unit 312, the storage control unit 313 causes the auxiliary storage device 33 to store the acquired latest data distribution file. The case where the data distribution file is stored in the auxiliary storage device 33 includes deleting, adding, overwriting, and changing the commodity master file stored in the auxiliary storage device 33 based on the data distribution file.

[0131] The instruction output unit 314 outputs an update instruction of the data distribution file to the storage server 2 (ACT 25). In ACT 25, for example, the instruction output unit 314 outputs a move instruction of the data distribution file to the storage server 2. In this case, the storage server 2 moves the data distribution file from the distribution file directory to the synchronization completion directory. The instruction output unit 314 may output a delete instruction of the data distribution file to the storage server 2. In this case, the storage server 2 may delete the data distribution file from the distribution file directory. The storage server 2 may delete the data distribution file from the auxiliary storage device 23.

[0132] In the above example, the updating of the commodity master file is taken as an example, but the invention is not limited thereto. In addition to being applicable to the updating of the commodity master file, the above embodiment can also be applicable to the updating of the database of the promotion information or the peripheral device information.

[0133] (Effect)

[0134] The information processing system involved in the embodiment includes a cloud server 1 and an edge server 3, and the cloud server 1 obtains the updated data of each store from the database based on the update of the database that manages the data of multiple stores, and creates and outputs the data distribution file of each store based on the updated data of each store so that the data distribution file created by the file creation unit can be stored in the storage device. In the case where the data distribution file of the store associated with the edge server 3 is stored in the storage device, the edge server 3 obtains the data distribution file of the store associated with the edge server 3, and can update the database based on the data distribution file of the store associated with the edge server 3.

[0135] For example, when a database such as a product master file is updated, the cloud server 1 creates a data distribution file containing updated data for each store based on the updated data and outputs the data distribution file to a storage area of ​​a storage device such as a storage server 2 for distributing the data distribution file to each store. The storage server 2 stores the data distribution file in a storage area assigned to each store. The edge server 3 obtains the data distribution file of the store associated with the edge server 3, and updates the database such as the product master file based on the obtained data distribution file.

[0136] Therefore, the cloud server 1 creates a data distribution file for each store and stores it in the storage server 2, so the edge server 3 only obtains the data distribution file of the store associated with the edge server 3 and synchronizes the product master file, etc. According to this, the information processing system can realize that the edge server 3 only synchronizes the updated data of the object. The edge server 3 can obtain only the object data and can reduce the processing load.

[0137] In addition, since the edge server 3 can obtain updated data without accessing the cloud server 1, access from edge servers of multiple stores will not be concentrated on the cloud server 1. As a result, the information processing system can synchronize the data on the cloud server with the edge server 3 without causing a load on the database of the cloud server 1.

[0138] In the information processing system according to the embodiment, the edge server 3 can output a request regarding the presence or absence of a data distribution file of a store associated with the edge server 3. Therefore, the edge server 3 can obtain the data distribution file based on the response to the request. Thus, the information processing system can reduce the burden of synchronization processing of update data based on the edge server 3.

[0139] In the information processing system involved in the embodiment, the edge server 3 can output an update instruction of the data distribution file. Therefore, the storage server 2 can update the data distribution file based on the update instruction. For example, the storage server 2 can move or delete the data distribution file between directories. Thus, the information processing system can prevent double synchronization of the edge server 3.

[0140] In the information processing system according to the embodiment, the cloud server 1 can create a data distribution file associated with the edge server 3 for each edge server. Therefore, the information processing system can reduce the data volume of the data distribution file stored in the storage server 2.

[0141] In the information processing system according to the embodiment, the cloud server 1 can create a data distribution file every time the database is updated. Therefore, the information processing system can simplify the creation process of the data distribution file based on the cloud server 1.

[0142] In the information processing system involved in the embodiment, the cloud server 1 can update the data distribution file every time the database is updated. Therefore, the cloud server 1 can create the data distribution file based on the latest updated data. Accordingly, the information processing system can reduce the amount of data in the data distribution file stored in the storage server 2.

[0143] In the information processing system according to the embodiment, the edge server 3 can obtain all the data distribution files related to the edge server 3. Therefore, the information processing system can simplify the acquisition process of the data distribution files of the edge server 3.

[0144] In the information processing system involved in the embodiment, the edge server 3 can obtain the latest data distribution file associated with the edge server 3. Therefore, the information processing system can reduce the amount of data in the data distribution file obtained by the edge server 3. In addition, the edge server 3 can synchronize the updated data based on the latest data distribution file. Therefore, the information processing system can simplify the synchronization process of the edge server 3.

[0145] In the information processing system according to the embodiment, the edge server 3 can output a request at a predetermined interval. The edge server 3 can determine whether there is a data distribution file based on the response to the request. Therefore, the information processing system can easily determine whether there is updated data.

[0146] In the information processing system involved in the embodiment, the edge server 3 can output an update instruction to move the data distribution file to the completion directory. In addition, the edge server 3 can output an update instruction to delete the data distribution file. Therefore, the storage server 2 can move or delete the data distribution file between directories based on the update instruction. As a result, the information processing system can prevent double synchronization based on the edge server 3.
