Furthermore, at least some of these components 101-105, 111-117 may be realized by dedicated hardware (circuits, etc.).

[0036] The first web service processing unit 101 causes the device 11 to execute applications to implement various service-related functions. The functions of the first web service processing unit 101 are realized by the CPU 41 (see Figure 3) operating according to programs downloaded by the browser 151 of the device 11 in the format of JAVASCRIPT® or CSS (Cascading Style Sheets). The first web service processing unit 101 includes an application execution unit 121 and an image composition unit 122. The application execution unit 121 executes the application. The application execution unit 121 displays application information obtained from the application management unit 103 to the user and requests the device 11 and the application management unit 103 to execute the application according to the user's settings. Inquiries by the user are also made, for example, by transitioning to an inquiry screen from an error screen displayed on the device 11 when application execution fails, such as an authentication error, or from a menu screen displayed after logging in. The image composition unit 122 executes the display of the application screen, presents the necessary parameters to the user, and accepts input.

[0037] The second web service processing unit 102 causes the information processing device 12 to execute applications to realize various functions related to the service. The functions of the second web service processing unit 102 are realized by the CPU 21 (see Figure 2) operating according to programs downloaded by the browser 161 of the information processing device 12 in the format of JAVASCRIPT® or CSS. The second web service processing unit 102 includes an application execution unit 131 and an image configuration unit 132. The application execution unit 131 executes an application for configuring the application. The application execution unit 131 accepts input from the sales representative and requests the application management unit 103 to change default values, etc. The application execution unit 131 also requests authentication to the authentication management unit 104 to display personal settings, and if authentication of external services such as file upload destinations is required in the application settings, it requests the authentication management unit 104 to obtain authentication information. The image configuration unit 132 executes the display of the application screen, presents the necessary parameters to the sales representative, and accepts input.

[0038] The authentication management unit 104 performs processing to acquire (extract) and update tenant information, user information, authentication information, contract information, similar tenant information, and device linkage information. Updating includes merging and deletion. The authentication management unit 104 also stores authentication information in the authentication information storage unit 114 and performs processing to manage logins and access restrictions for users, sales representatives, devices, etc.

[0039] The authentication information storage unit 114 stores authentication information such as access tokens for users and sales representatives.

[0040] The tenant information storage unit 112 stores tenant information that defines tenants for demarcating the service provision area. Table 1 below shows an example of tenant information.

[0041] [Table 1]

[0042] The user information storage unit 113 stores user information that is linked to tenant information and used for user identification. Table 2 below shows an example of user information.

[0043] [Table 2]

[0044] The contract information storage unit 115 stores contract information that defines the usage rights of services used by users on a per-tenant basis. Table 3 below shows an example of contract information.

[0045] [Table 3]

[0046] The device linkage information storage unit 117 stores device linkage information that links the devices 11 used to provide the service with the tenant. Table 4 below shows an example of device linkage information.

[0047] [Table 4]

[0048] The email sending unit 105 maintains the mechanism by which the service provision system 1 sends emails. In this embodiment, the example shown is sending an email, but if information on contact methods other than email addresses is registered, the email sending unit 105 maintains a mechanism that allows information to be sent to other systems such as SNS.

[0049] The similar tenant information storage unit 116 stores similar tenant information, which is a list of similar tenants compiled by the first web service processing unit 101.

[0050] Figure 5 is a sequence diagram showing an example of processing when an inquiry is made in the service provision system 1 according to the embodiment. When a user (customer) performs a login operation on the device 11, the browser 151 and the first web service processing unit 101 of the device 11 display a menu screen (S1-S7). In this example, an error occurs when using the application, and an inquiry is made (S9-S11). By pressing the transition button for the inquiry URL displayed on the error screen when the error occurs, the inquiry screen is displayed on the display of the device 11. When the user enters the content and details of the inquiry on the displayed inquiry screen, the inquiry content is sent to the first web service processing unit 101 (S12, S13). Alternatively, if the desired application is not displayed on the menu screen, an inquiry can be made in the same way by transitioning from the menu screen to the inquiry screen.

[0051] In this embodiment, the first web service processing unit 101 generates a similar tenant list by grouping tenant information similar to the tenant information corresponding to the tenant associated with the device 11 that sent the inquiry information. The email sending unit 105 notifies the information processing device 12 used by the sales representative via email of a confirmation screen URL (an example of link information) that allows the sales representative to check the inquiry details and the similar tenant list.

[0052] Specifically, first, the first web service processing unit 101 sends an information acquisition request to the authentication management unit 104 along with the unique device ID assigned to the device 11 that sent the inquiry information (S14). The authentication management unit 104 searches the device linkage information storage unit 117 for the tenant ID associated with the received device ID and sends it to the first web service processing unit 101 (S15-S18). The first web service processing unit 101 sends a tenant information acquisition request to the authentication management unit 104 to obtain tenant information corresponding to the received tenant ID (S19). In response to the tenant information acquisition request, the authentication management unit 104 extracts the tenant information corresponding to the searched tenant ID from the tenant information storage unit 112 and sends it to the first web service processing unit 101 (S20-S22).

[0053] The first web service processing unit 101 compares the extracted tenant information with the tenant information corresponding to the device 11 that sent the inquiry information, and generates a similar tenant list by grouping tenant information with a specified number or more similar items (S23). The authentication management unit 104 stores the similar tenant list in the similar tenant information storage unit 116 in response to the similar tenant list registration request sent from the first web service processing unit 101 (S24-S27).

[0054] Subsequently, the first web service processing unit 101 sends a notification request to the sales representative requesting that a notification email containing the inquiry details and a list of similar tenants be sent, and the email sending unit 105 sends the notification email to the information processing device 12 in response to the notification request (S28-S30). The authentication management unit 104 and the first web service processing unit 101 display on the browser 151 of the device 11 that the inquiry has been completed (S31-S33).

[0055] Figure 6 is a sequence diagram showing an example of processing when the service provision system 1 according to the embodiment responds to an inquiry. When a sales representative receives a notification email, they can access a screen where they can check a list of similar tenants, etc., through the browser 161 of the information processing device 12. When the sales representative accesses the confirmation screen URL in the notification email, the second web service processing unit 102 requests login for authentication, and the login screen is displayed in the browser 161 of the information processing device 12 (S51, S52). When the sales representative enters the information necessary for login and submits it, the second web service processing unit 102 uses the received information to perform login authentication (S53~S55).

[0056] Once authentication is complete, the second web service processing unit 102 retrieves the list of similar tenants from the similar tenant information storage unit 116 and displays the similar tenant confirmation screen (S56-S60). The second web service processing unit 102 then prompts the sales representative to select the tenant group to operate on based on the information in the similar tenant list and displays the group operation screen (S61, S62).

[0057] The sales representative selects whether to merge or delete the target tenant on the group operation screen, and the selection result is sent to the second web service processing unit 102 (S63). If merging is selected, the authentication management unit 104, which receives a processing reflection request from the second web service processing unit 102, integrates the tenant information of the merge source into the merge destination and reflects it in the tenant information storage unit 116 (S64-S74). At this time, the second web service processing unit 102 first displays a merge operation screen on the information processing device 12 for selecting the information to be used when integrating, and allows the sales representative to individually select the tenant information they wish to use. Upon receiving the selection, the second web service processing unit 102 generates tenant information based on the selected information through a merge process and sends it to the authentication management unit 104. The authentication management unit 104 updates the merge destination tenant information in the tenant information storage unit 116 based on the transmitted information, and deletes the merge source tenant after the update is complete. Subsequently, if there are users in the user information storage unit 113 who have been assigned the merge source tenant ID, the authentication management unit 104 assigns the merge destination tenant ID to the target users. If deletion is selected, the authentication management unit 104 deletes the tenant information to be deleted from the tenant information storage unit 116 (S75-S78).

[0058] If a tenant linked to the device 11 that generated the inquiry during the merge and delete process is deleted, the information is sent to the device linkage storage unit 117 and re-linked to the grouped tenant IDs that were not deleted (S79~S82). After the selected process is completed, the email sending unit 105 notifies the user of the inquiry response, and the second web service processing unit 102 displays the completion of the process on the browser 161 of the information processing device 12 (S83~S88).

[0059] Figure 7 shows an example of an inquiry screen 51 according to the embodiment. The inquiry screen 51 illustrated here is the screen displayed on the browser 151 of the device 11 in step S13 of Figure 5. The user selects an inquiry from the list, optionally enters a detailed explanation in the text box, and then presses the send button to send the inquiry to the first web service processing unit 101. The inquiry content entered here is included together with the notification email that notifies the user of a list of similar tenants, etc.

[0060] Figure 8 shows an example of a notification email 56 according to the embodiment. The notification email 56 illustrated here is an email sent to the sales representative (information processing device 12) in step S30 of Figure 5. The notification email 56 includes the user who sent the inquiry (customer name), the device ID indicating the device 11 from which the inquiry was sent, the tenant ID indicating the tenant linked to the device 11, the content of the inquiry, the details of the inquiry, a confirmation screen URL 301, and grouped tenant information 302. The content and details of the inquiry are those entered on the inquiry screen 51. By accessing the confirmation screen URL 301, a list of similar tenants can be displayed on the information processing device 12. The grouped tenant information 302 is information that groups tenants similar to the tenant linked to the device 11.

[0061] Figure 9 shows an example of a confirmation screen 61 according to the embodiment. The confirmation screen 61 illustrated here is the confirmation screen for the similar tenant list 311 displayed in step S60 of Figure 6. The similar tenant list 311 is displayed in the browser 161 of the information processing device 12 used by the sales representative, and the grouped tenant names and similar items are arranged so that they can be visually compared. The items used as the basis for grouping are highlighted so that they can be visually judged. If there is information for multiple grouped similar tenants, they are arranged so that they can be viewed by scrolling, and by selecting the group that you want to operate on, the selected information is sent to the second web service processing unit 102 and you can transition to the group operation screen.

[0062] Figure 10 shows an example of a group operation screen 66 according to the embodiment. The group operation screen 66 illustrated here is the screen displayed in step S62 of Figure 6. From the group operation screen 66, the sales representative can select merging or deleting the target tenant as a means of resolving the inquiry. In the case of merging, the sales representative selects the source tenant to be merged and the destination tenant to be merged and presses the execute button. In the case of deletion, the sales representative selects the tenant to be deleted and presses the execute button. When the execute button is pressed, the selected information is sent to the second web service processing unit 102 and the authentication management unit 104, and the selected process is executed. After the completion of the process, the processing result is displayed on the information processing device 12. The email sending unit 105 also notifies the user of the inquiry response result by email or other means.

[0063] Figure 11 shows an example of a merge operation screen 71 according to the embodiment. Figure 12 shows an example of a merge completion screen 76 according to the embodiment. The merge operation screen 71 illustrated here is the screen displayed in step S64 of Figure 6, and the merge completion screen 76 is the screen displayed in step S88 of Figure 6. On the merge operation screen 71, you can select individual information to be reflected in the merge destination tenant. At this time, information that is uniquely determined when the merge destination tenant is selected, such as the tenant ID, cannot be selected, and values ​​that are not eligible will be half-brightened. Also, for information that can be held multiple times, such as the contract ID, all information will be reflected in the merge destination tenant. When the process execution button on the merge operation screen 71 is pressed and the process is completed, the merge completion screen 76 is displayed on the information processing device 12. On the merge completion screen 76, a table is displayed in which you can check the information that has been finally reflected in the merge destination tenant.

The programs may also be configured to be provided by recording them in an installable or executable file format on a computer-readable recording medium such as a CD-ROM, flexible disk (FD), CD-R, or DVD (Digital Versatile Disk).

[0065] The program may be configured to be stored on a computer connected to a network such as the Internet and provided by being downloaded via the network. The program may also be configured to be provided or distributed via a network such as the Internet. The program has a modular structure including the functional units described above, and in actual hardware, the processor (e.g., CPU 21, 41, etc.) reads the program from a storage device and executes it, thereby loading the functional units onto the main memory and generating them on the main memory.

[0066] According to the above embodiment, tenant information similar to the tenant associated with the device to which a user has made an inquiry (sent inquiry information) is grouped together. Then, based on the result of this grouping (e.g., similar tenant list), the information in the database (e.g., tenant information, user information, contract information, device linkage information, etc.) is updated. Furthermore, sales representatives can correct (merge or delete) duplicate tenant information while checking the similar tenant list. This makes it easy to correct duplicate tenant entries in the database and improves the maintainability of the system. [Explanation of symbols]
