  Hereinafter, examples of embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram illustrating the configuration of an information processing system 1 according to an embodiment of the invention. As shown in FIG. 1, the information processing system 1 includes a server 2 and a plurality of client terminals 4. The client terminal 4 is a personal computer or a so-called multifunction machine. The server 2 is a known server computer and includes a microprocessor, a main memory, a hard disk, a display, a network interface, and the like. Various programs are stored in the main memory. These programs are read from a computer-readable information storage medium and stored in the main memory. Alternatively, it is received from the program holding device via a public communication line and stored in the main memory.

  The server 2 and each client terminal 4 are connected to a dedicated mail server (not shown) via a local area network. As shown in the figure, the server 2 and each client terminal 4 are connected to a wide area network (that is, WAN) and can communicate with each other. The user accesses the server 2 using his / her client terminal 4.

  FIG. 2 is a diagram illustrating the configuration of the server 2. As shown in the figure, the server 2 includes a data storage unit 6, a user information storage unit 8, an authentication state storage unit 10, an authentication unit 12, a data processing unit 14, a processing result output unit 16, an event detection unit 18, and a notification unit. 20, a notification definition storage unit 22, a notification mode storage unit 24, and a notification information holding unit 26. These are realized by executing the program stored in the main memory by the microprocessor.

  The data storage unit 6 is realized by a hard disk and stores a plurality of data. For example, the data is a document generated by a document creation application. The user information storage unit 8 is realized by a hard disk and stores user information of each user. FIG. 3 illustrates user information. As shown in the figure, the user information includes a user ID, which is a user identification ID, a user email address, a user name, and the like. The authentication information storage unit 10 is realized by a hard disk, and holds an authentication flag indicating whether or not the user has been logged in for each user. When the user is logged in, the value of the authentication flag is set to “logged in”, and when the user is not logged in, the value of the authentication flag is set to “logged out”. The authentication unit 12 is realized by a microprocessor and authenticates a user who has accessed the server 2. When the user logs in, the authentication unit 12 sets the value of the authentication flag to “logged in”. When the user logs out, the authentication unit 12 sets the value of the authentication flag to “logged out”.

  Hereinafter, a user who is logged in is referred to as a login user, and a user who is not logged in is referred to as a non-login user.

  The data processing unit 14 and the processing result output unit 16 are realized by a microprocessor. The data processing unit 14 processes data stored in the data storage unit 6. In this embodiment, the data processing unit 14 processes data when a processing request is accepted from the client terminal 4 of the login user. Examples of processing include data update, addition, acquisition, and deletion. The processing result output unit 16 causes the output unit to output the processing result by the data processing unit 14. In the case of the present embodiment, the processing result output unit 16 causes the output unit to output the processing result for the login user. More specifically, the processing result output unit 16 causes the network interface to return the processing result to the client terminal 4 of the login user.

  The event detection unit 18 is realized by a microprocessor, and the event detection unit 18 detects that an event has occurred regarding data stored in the data storage unit 6.

  The notification unit 20 is realized by a microprocessor. The notification unit 20 will be described later.

  The notification definition storage unit 22, the notification mode storage unit 24, and the notification information holding unit 26 are realized by a hard disk. The notification definition storage unit 22 stores a notification definition for each specific event among events that occur with respect to data stored in the data storage unit 6. FIG. 4 illustrates the notification definition. As shown in the figure, the notification definition includes a notification definition ID, an event type of a specific event, a user ID of one or a plurality of notification destination users predetermined for the specific event, and a predetermined definition for the specific event. Holds notification content. The specific event is an event other than data acquisition, for example.

  The notification mode 24 stores notification mode information for each user. FIG. 5 illustrates notification mode information. As shown in the figure, the notification mode information includes the user ID of the user and the notification mode of the user. Either the normal mode or the hold mode is set as the notification mode. When the user's notification mode is the hold mode, the notification mode information includes the hold start time. The hold start time indicates a time when the user notification mode is switched from the normal mode to the hold mode. The notification information holding unit 26 will be described later.

  FIG. 6 is a diagram illustrating processing executed by the server 2. This process is executed by the notification unit 20 when the event detection unit 18 detects that some event has occurred regarding the data stored in the data storage unit 6.

  First, the notification unit 20 specifies the event type of the event that has occurred (S101), and acquires a notification definition including the specified event type from the notification definition storage unit 22 (S102). If the generated event is a specific event, the notification definition of the specific event is acquired.

  Note that the notification unit 20 also issues a unique notification ID in step S102. The notification definition acquired in S102 (hereinafter referred to as notification definition X) is illustrated on the right side of FIG.

  Then, the notification unit 20 sequentially selects each of the notification destination users included in the notification definition X as the notification destination user U, and executes the processes shown in S103 and S104 for the selected notification destination user U. That is, the notification unit 20 determines whether or not the notification destination user U is “logged in” based on the stored contents of the authentication information storage unit 10 (S103), and the notification destination user U is “logged in”. If there is (Yes in S103), the notification destination user U is registered in the main memory as a notification target user (S104). That is, the notification unit 20 stores the user ID of the notification destination user U in the main memory. The stored contents of the main memory are illustrated on the right side of FIG.

  Then, the notification unit 20 generates a notification message (S105). Specifically, the notification unit 20 generates a notification message based on the notification content included in the notification definition X. Hereinafter, the notification message generated in step S105 is referred to as a notification message M.

  Thereafter, the notification unit 20 determines whether or not a notification target user is registered in the main memory (S106). If there is no notification target user (No in S106), the notification unit 20 executes predetermined mail processing (S108). ). The mail processing will be described later.

  On the other hand, when there is even one notification target user (Yes in S106), the notification unit 20 sets “notification target user can view the notification message X” using a method other than the transmission of the e-mail (S107).

  Specifically, the notification unit 20 notifies the notification ID (here, “notification P”) issued in step S102, the notification message M, the flag set to the value “not notified”, and the notification definition X. The notification content information including the notification definition ID is generated and stored in the notification information holding unit 26 (see FIG. 2). The notification content information is illustrated on the left side of FIG.

  In addition, the notification unit 20 generates notification information for each notification target user and stores the notification information in the notification information holding unit 20. Here, the notification information includes the notification ID issued in step S102, the user ID of the notification target user, the notification information set to the value “registered”, and the registration time. Here, the current time is stored as the registration time. By setting the notification information to “registered”, the notification message M is set to be viewable by the notification target user. The reason why the notification information is set to “registered” means that the notification message M is set to be viewable by the notification target user will be described later (see FIG. 10). The notification information is illustrated on the left side of FIG. As described above, the notification content information and each notification information include the notification ID (that is, “notification P”) issued in step S102 in common. Therefore, each notification information is associated with the notification content information through this notification ID.

  Next, the mail process executed in step S108 will be described. The mail process is illustrated in FIG. In the mail processing, the notification unit 20 sequentially selects each of the notification destination users included in the notification definition X as the notification destination user U, and executes the processing shown in S201 to S203 or S204 for the selected notification destination user U. To do.

  That is, the notification unit 20 determines whether or not the notification mode of the notification destination user U is the hold mode based on the storage content of the notification mode storage unit 24 (see FIG. 2) (S201), and the notification destination user U If the notification mode is the normal mode (No in S201), the notification destination user U is registered in the main memory as a notification target user in the same manner as in Step S104 (S202). Further, the notification mode of the notification destination user U is switched to the hold mode (S203).

  On the other hand, if the notification mode of the notification destination user U is the hold mode (Yes in S201), the notification unit 20 executes a hold process (S204). In the hold process, the notification unit 20 generates notification content information in the same manner as in step S <b> 107 and stores it in the notification information holding unit 26. That is, the notification unit 20 notifies the notification ID (that is, “notification P”) issued in step S102, the notification message M, the flag set to the value “not yet notified”, and the notification definition in the notification definition X. Notification content information including the ID is generated and stored in the notification information holding unit 26. The notification content information is illustrated on the right side of FIG.

  In the hold process, the notification unit 20 generates the notification information regarding the notification destination user U and stores it in the notification information holding unit 20. In the hold process, the notification information includes the notification ID issued in step S102. Further, the user ID of the notification destination user U is included. However, the notification state is set to “not yet” instead of “registered”. In this case, since the notification state is set to “not yet” instead of “registered”, the notification message M is not viewable by the notification destination user U. Also, the registration time is set to “null”. The notification information is illustrated on the right side of FIG. As described above, the notification content information and each notification information include the notification ID issued in step S102 in common. Therefore, each notification information is associated with the notification content information via the notification ID.

  Then, the notification unit 20 determines whether or not a notification target user is stored in the main memory (S205), and if there is only one notification target user (yes in S205), an email is transmitted to each notification target user. (S206). That is, the notification unit 20 specifies the email address of each notification target user based on the stored contents of the user information storage unit 8, and sends an email including the notification message M generated in step S105 to each notification target user. Send with. In this way, the notification message M is placed in a state that can be viewed by each notification target user. The notification message M is browsed when the notification target user starts the mail application.

  As described above, in the server 2, when a specific event occurs, a notification message for notifying the occurrence of the specific event is placed in a state that can be viewed by the notification destination user by sending an e-mail. However, when the notification destination user is logged in, the notification message is placed in a state where it can be viewed by a method other than the transmission of the e-mail. Further, since the notification mode is switched from the normal mode to the hold mode for the notification destination user who has transmitted the e-mail, the e-mail is not continuously transmitted. For this reason, it is possible to achieve both suppression of information transmission delay and reduction of the mail server load.

  In addition, it is estimated that the user who confirmed the e-mail on the go, for example, returns to his client terminal 4 and accesses the server 2. For this reason, once the notification message is sent by e-mail and then the notification message is continuously sent by e-mail, the mail server is unnecessarily burdened. Therefore, in the server 2, when the user (hereinafter referred to as the login user X) logs in, that is, when the authentication flag is switched from “logged out” to “logged in”, the notification unit 20 causes the server 2 to display FIG. The illustrated process is performed.

  Hereinafter, FIG. 8 will be described. Hereinafter, notification information whose notification state is “not yet” is referred to as hold notification information. Further, the hold notification information is distinguished by the user ID in the hold notification information. For example, hold notification information including a user ID of a certain user is expressed as hold notification information addressed to the certain user. A notification message included in notification content information associated with hold notification information addressed to a certain user is referred to as a hold notification message addressed to the certain user.

  First, the notification unit 20 specifies the hold notification information addressed to the login user X among the hold notification information stored in the notification information holding unit 26 (S301). Then, the notification unit 20 makes “the login user X can view the hold notification message addressed to the login user X” by a method other than the transmission of the e-mail (S302). That is, the notification unit 20 updates the notification state in the hold notification information addressed to the login user X to “registered”. In addition, in step S302, the notification unit 20 sets the current time as the registration time in the hold notification information addressed to the login user X. The reason why updating the notification information to “registered” means “making the hold notification message viewable to the login user X” will be described later (see FIG. 10).

  Further, the notification unit 20 deletes the hold notification information addressed to other users (S303). More specifically, the notification unit 20 deletes the hold notification information addressed to other users associated with the same notification content information as the hold notification information addressed to the login user X.

  For example, as illustrated in FIG. 9A, in association with the notification content information X, the hold notification information addressed to the login user X and the hold notification information addressed to the user Y who is not the login user X are stored in the notification information holding unit 26. It is assumed that In this case, the hold notification information addressed to the login user X is specified in step S301. In step S302, as shown in FIG. 9B, the notification state value in the hold notification information addressed to the login user X is updated to “registered”. Also, the current time is set as the registration time in the hold notification information. If a notification message is notified to one of the notification destination users, it is not necessary to notify other notification destination users. Therefore, the hold notification information addressed to user Y is deleted in step S303.

  Then, the notification unit 20 updates the notification mode of the login user X to the normal mode (S304).

  Hereinafter, the notification information in which the notification state is “registered” is referred to as registered notification information. Also, the registered notification information is distinguished by the user ID in the registered notification information. For example, registered notification information including a user ID of a certain user is expressed as registered notification information addressed to the certain user. A notification message included in notification content information associated with registered notification information addressed to a certain user is referred to as a registered notification message addressed to the certain user.

  Next, a scene where the registered notification message is browsed will be described with reference to FIG. FIG. 10 is a diagram illustrating processing executed by the server 2 in this scene. This process is executed when the server 2 accepts a processing request from the client terminal 4 of the login user (hereinafter referred to as the login user X).

  That is, the notification unit 20 specifies registered notification information addressed to the login user X among the notification information stored in the notification information holding unit 26 after the data processing unit 14 performs processing (S401). Then, the processing result output unit 16 returns a registered notification message addressed to the login user X together with the processing result of the data processing unit 14 to the client terminal 4 of the login user X (S402). The returned processing result and registered notification message are displayed on the display of the client terminal 4 of the login user X. The registered notification message may be transmitted as a so-called instant message.

  Then, the notification unit 20 updates the notification state value in the registered notification information addressed to the login user X (S403). That is, as a result of step S402, the registered notification message is displayed on the display of the client terminal 4 of the logged-in user X. Therefore, the notification unit 20 changes the notification state value from “registered” to “displayed”. Update to In addition, in step S403, the notification unit 20 may update the flag value included in the notification content information associated with the registered notification information addressed to the login user X from “not notified” to “notified”. Do. In addition, the transition of the content of the registered notification information addressed to the login user X is illustrated on the left side of FIG.

  As described above, in the server 2, the processing illustrated in FIGS. 6, 7, 8, and 10 is performed so as to prevent unnecessary load on the mail server while suppressing delay in information transmission.

  This is not the only characteristic of the server 2. For example, when a user who confirms an e-mail on the go cannot easily return to his / her client terminal 4, the confirmation of the notification message is delayed. Therefore, in the server 2, the processing illustrated in FIG. 11 is periodically executed by the notification unit 20.

  That is, the notification unit 20 refers to the stored content of the notification mode storage unit 24 and identifies the long-term holding user (S501). That is, the notification unit 20 identifies a user whose notification mode is the hold mode and whose elapsed time from the hold start time to the current time is equal to or longer than the reference time as a long-term hold user.

  And the notification part 20 selects each long-term holding user in order as the user X, and performs the step of S402 thru | or S404 about the user X. That is, the notification unit 20 specifies the pending notification information addressed to the user X among the notification information stored in the notification information holding unit 26 (S502).

  And the notification part 20 transmits mail with respect to the user X (S503). That is, the notification unit 20 specifies the mail address of the user X based on the stored contents of the user information storage unit 8, and transmits an email including a hold notification message addressed to the user X to the user X.

  Further, the notification unit 20 deletes the hold notification information specified in step S502 (S504).

  When all the notification information associated with the notification content information is deleted as a result of performing the processing of S502 to S504 for all long-term holding users, the notification unit 20 deletes the notification content information. Note that, in step S501, the notification unit 20 specifies a user whose notification mode is the hold mode and whose hold notification information addressed to himself is stored in the notification information holding unit 26 for a reference number or more as a long-term hold user. May be.

  Further, the server 2 does not have this feature. For example, even if a user who returns to his / her client terminal 4 from an outside location logs in to the server 2, if nothing is performed thereafter, confirmation of the registered notification message is delayed. Therefore, in the server 2, the processing illustrated in FIG. 12 is periodically executed by the notification unit 20.

  Hereinafter, the process of FIG. 12 will be described. Hereinafter, notification information whose notification state is “displayed” is referred to as “displayed notification information”. The displayed notification information is distinguished by the user ID in the displayed notification information. For example, displayed notification information including a user ID of a certain user is expressed as displayed notification information addressed to the certain user.

  First, the notification unit 20 identifies registered notification information in the notification information holding unit 26 (S601). Then, the notification unit 20 sequentially selects each registered notification information specified in step S601 as registered notification information X, and executes steps S602 to S606 for the registered notification information X.

  That is, the notification unit 20 determines whether or not the elapsed time from the registration time to the current time in the registered notification information X is equal to or longer than the reference time (S602). When the elapsed time is equal to or longer than the reference time (Yes in S602), the notification unit 20 deletes the registered notification information X (S603). Further, the notification unit 20 determines whether or not the displayed notification information is associated with the notification content information associated with the registered notification information X (hereinafter referred to as notification content information X) (S604). . Specifically, the notification unit 20 determines whether or not the value of the flag in the notification content information X is “notified”. In step S604, it is determined whether or not the notification message in the notification content information X has been notified to any user.

  When no displayed notification information is associated with the notification content information X (No in S604), the notification unit 20 acquires a notification destination user in the notification content information X (S605). And the notification part 20 performs the mail process shown in FIG. 7 by making the notification message in the notification content information X into the notification message M (S606).

  If the registered notification message is not confirmed by the user for a certain period of time by the processing of FIG. 12, the registered notification message is sent by e-mail.

  In addition, embodiment of this invention is not restricted only to the said embodiment.

  For example, when the server 2 accepts a processing request from the client terminal 4 of the login user (hereinafter referred to as the login user X), not only the processing illustrated in FIG. 10 but also the processing illustrated in FIG. 13 is executed. Good.

  Hereinafter, FIG. 13 will be described. First, the notification unit 20 specifies the displayed notification information addressed to the login user X among the notification information stored in the notification information holding unit 26 (S701). Then, the notification unit 20 sequentially selects each of the displayed notification information specified in step S701 as the notification information X, and executes the processing of S702 for the notification information X.

  That is, the notification information 20 deletes the notification information associated with the notification information X (hereinafter referred to as the notification content information X) other than the registered notification information (S702). ). Note that when all the notification information associated with the notification content information X is deleted as a result of the processing of S702, the notification unit 20 deletes the notification content information X.

  Further, for example, the notification unit 20 changes the value of the flag included in the notification content information associated with the registered notification information addressed to the login user X from “not notified” to “notified” in step S403 of FIG. Instead of updating the notification content information, the notification content information and all the notification information associated therewith may be deleted.
