JP6015392B2 - Server apparatus, document management system, and program - Google Patents

Description

  The present invention relates to a server device, a document management system, and a program.

  There is known a document management system in which a server device stores a document and receives editing of the document from a client device. In the document management system, a plurality of client devices may edit the same document at the same time zone.

  For example, Patent Document 1 discloses a document that discloses a technique for preventing conflicts in editing contents of a document. In the schedule management system of Patent Document 1, a locked document is created before reservation registration. The schedule management system performs exclusive control of reservation registration based on the presence or absence of the locked document.

  Generally, in a document management system, when there is a conflict in editing contents when a document is saved, the server device determines whether the editing contents conflict and whether or not to save the editing contents as they are. A message to be confirmed (hereinafter referred to as “conflict confirmation message”) is displayed on the client device.

  At this time, if the client device saves the document in a state where the editing content is in conflict, the editing content of another client device that has previously edited the document is overwritten. In order to prevent this, it is necessary to cancel the editing once without saving the document in a state where the editing contents are in conflict. That is, the client device needs to close the document without saving the edited contents, reopen the document, and save the document.

  However, the above-described conflict confirmation message cannot be used when an agent program or the like started according to a regular schedule edits a document. For this reason, when the agent program detects a conflict of editing contents, a predetermined exclusive control process is executed. Generally, the predetermined exclusive control process includes the following (1) to (3). (1) The document is saved in a constantly conflicting state. (2) Always save the document. (3) Retry saving the document a predetermined number of times (opening and saving the document again).

  However, in the conventional exclusive control process, it is necessary to execute some post-processing after the exclusive control process is performed. For example, in the case of (1) described above, it is necessary to execute a post-process for merging the overwritten editing content with the document overwritten by the agent program. Further, in the case of the above (2) and in the case of all the retries failing in the above (3), it is necessary to execute a post-process for executing again the processing of the canceled agent program.

  However, it is difficult for the exclusive control processing that requires post-processing as described above to maintain document consistency in real time. For example, if a time lag occurs during the execution of the above-described post-processing after the processing is canceled by the agent program, the document cannot be managed in a state where consistency is maintained in real time.

  SUMMARY An advantage of some aspects of the invention is that it provides a server device, a document management system, and a program that can maintain document consistency more appropriately.

  In order to solve the above-described problems and achieve the object, the server device of the present invention receives a message including a storage unit that stores a document, an editing reception unit that receives the editing of the document, and an editing content of the document A server device, and an agent activation unit that activates an agent program that edits the document according to the edited content included in the received message, the agent program including the server device, The edited document when it is determined that the edited content included in the message conflicts with the edited content received by the edit receiving unit and the determination unit. The message that triggered the start of the agent program when it is determined that there is a conflict. The message containing the same edits and edits contained, to function as a transmission unit for transmitting to the receiving unit.

  The document management system of the present invention is a document management system comprising a server device and a client device connected to the server device via a network, the server device having a storage unit for storing a document, An edit accepting unit that accepts editing of the document, a receiving unit that receives a message including the editing content of the document, and an agent activation that activates an agent program that edits the document according to the editing content included in the received message A determination unit that determines whether the editing content included in the message conflicts with the editing content received by the editing reception unit; When it is determined that there is no conflict, there is a conflict with the edit storage unit that stores the edited document. If it is determined that the message is included in the message that triggered the start of the agent program, the message including the same editing content as the transmission content, function as a transmission unit that transmits to the reception unit, the client device, The document is edited by sending an email including the edited contents of the document or by using the editing reception unit.

  The program of the present invention receives a computer, a storage unit that stores a document, an editing reception unit that receives editing of the document, a receiving unit that receives a message including the editing content of the document, and the message , Functioning as an agent activation unit that activates an agent program that edits the document according to the editing content included in the message, and the agent program stores the document edited according to the editing content when the computer stores the document edited according to the editing content.

  Hereinafter, embodiments of a server device, a document management system, and a program will be described in detail with reference to the accompanying drawings.

(First embodiment)
FIG. 1 is a diagram illustrating an example of a configuration of a document management system 10 according to the first embodiment. A document management system 10 according to the present embodiment includes a server device 1 and client devices 2a, 2b to 2n. The client devices 2a, 2b to 2n may be an arbitrary number. Hereinafter, when the client devices 2a, 2b to 2n are not distinguished, they are simply referred to as the client device 2.

  The server device 1 and the client device 2 are connected via a network 3. Note that the communication method of the server device 1 and the client device 2 may be a wired method or a wireless method.

  The server device 1 includes an edit reception unit 11, a proxy edit reception unit 12, and a storage unit 15. The proxy edit reception unit 12 includes a reception unit 13 and an agent activation unit 14. The storage unit 15 stores a document management DB (Database) 16.

  The document management DB 16 stores documents. The document stored in the document management DB 16 may be an arbitrary document. For example, the document is a failure slip that manages events such as system errors and malfunctions, analysis results of the contents of the events, and how to deal with the events.

  The edit accepting unit 11 accepts editing of a document stored in the document management DB 16 from the client device 2. Note that the client device 2 may edit the document on the server device 1. The client device 2 may download the document to the client device 2 and edit the document, and upload the edited document to the server device 1.

  The receiving unit 13 receives a message including the edited content of the document from the client device 2. The message may be received by any method. For example, the message may be an email. The message may be a message received in an HTML (HyperText Markup Language) format, an XML (Extensible Markup Language) format, or the like using HTTP (HyperText Transfer Protocol) or the like.

  The agent activation unit 14 activates the agent program 4 that edits a document according to the editing content included in the message received by the reception unit 13. FIG. 2 is a diagram illustrating an example of the configuration of the agent program 4 of the document management system 10 according to the first embodiment. The agent program 4 includes a determination unit 41, an edit storage unit 42, and a transmission unit 43.

  The determination unit 41 determines whether or not there is a conflict with the editing content of the editing reception unit 11 when the document edited with the editing content included in the message is stored. When storing the edited document, the determination unit 41 may determine whether or not it is in conflict with the editing content of the editing reception unit 11 based on the time stamp of the document. In addition, when the edited document is stored, the determination unit 41 may determine whether or not there is a conflict with the editing content of the editing reception unit 11 based on the data size of the document.

  The edit storage unit 42 stores the edited document when the edited content of the edited document does not conflict with the edited content by the edit receiving unit 11. The transmission unit 43 includes the same editing content as the editing content included in the message that triggered the activation of the agent program 4 when the editing content of the edited document conflicts with the editing content by the editing reception unit 11. Send the message to the receiver. As a result, the agent program 4 creates a trigger for starting a new agent program 4 and terminates its own processing. That is, when the agent program 4 is restarted, it is possible to delay the timing of saving the edited content by the agent program 4.

  While the agent program 4 is running, the receiving unit 13 accepts other messages including other editing contents. The agent activation unit 14 may control the activation of the agent program 4 by managing a task that activates the agent program 4. Management of this task may be performed by FIFO (First In First Out). Further, the agent activation unit 14 may perform control so as to activate the next agent program 4 after confirming the end of the activated agent program 4. Further, the agent activation unit 14 may combine the editing contents included in the plurality of messages into the processing of one agent program 4.

  Here, the restart of the agent program 4 will be described by taking as an example a case where the message is a mail. First, the determination unit 41 determines that the editing accepting unit 11 and the editing content are in conflict.

  The transmission unit 43 newly creates an edited content (hereinafter referred to as “second mail”) that is the same as the edited content included in the text of the mail that triggers the activation of the agent program 4 (hereinafter referred to as “first mail”). Set to the text of "e-mail"). Further, the transmission unit 43 of the agent program 4 sets the address of the server device 1 as the transmission destination address of the second mail. The transmission unit 43 transmits the second mail.

  In addition, the transmission part 43 may divert and transmit the 1st mail, without creating a 2nd mail newly. When the receiving unit 13 is in another device for reasons such as load distribution, the address of the other device may be set as the transmission address of the second mail.

  When the reception unit 13 receives the second mail, the agent activation unit 14 activates the agent program 4 that edits the document according to the editing content included in the text of the second mail.

  FIG. 3 is a diagram for explaining an example in which document editing contents conflict in the document management system 10 according to the first embodiment. First, the receiving unit 13 of the proxy editing accepting unit 12 receives a message including the editing content of the document managed in the document management DB 16 from the client device 2a (step S1). The receiving unit 13 notifies the agent activation unit 14 that the message has been received (step S2). The agent activation unit 14 activates the agent program 4 (step S3).

  On the other hand, the edit accepting unit 11 accepts editing of the document (same document as the document reflecting the editing content included in step S1) managed in the document management DB 16 from the client device 2b (step S4). The edit accepting unit 11 stores the edited document in accordance with the operation of the user of the client device 2b (Step S5).

  Here, the determination unit 41 of the agent program 4 determines that the edited content included in the message of step S1 conflicts with the edited content of the edit receiving unit 11 before saving the edited content (step S6). ). The transmission unit 43 of the agent program 4 transmits to the reception unit 13 a message that includes the same editing content as the editing content included in the message that triggered the activation of the agent program 4 (step S7).

  As a result, the reception unit 13 notifies the agent activation unit 14 of the reception of the message again, so that the agent activation unit 14 activates (reactivates) the agent program 4. When the restarted agent program 4 saves the edited content, if the determination unit 41 determines that there is a conflict with the edited content of the edit receiving unit 11, the agent program 4 is restarted again. .

  FIG. 4 is a diagram for explaining the operation of the agent program 4 when document editing content conflicts in the document management system 10 according to the first embodiment. The user A of the client device 2 starts editing the document in the document management DB 16 stored in the storage unit 15 via the editing reception unit 11 of the server device 1 (step S11). The agent program 4 starts editing the document edited in step S11 (step S12). The user A of the client device 2 saves the document reflecting the edited content (step S13).

  The determination unit 41 of the agent program 4 determines whether or not the edited content of the agent program 4 conflicts with the edited content of the edit receiving unit 11 before saving the document reflecting the edited content (step S14). The determination unit 41 of the agent program 4 determines that the editing content is in conflict because the document is updated by the user A. Therefore, the edit storage unit 42 cancels the storage of the document reflecting the edited content (step S15).

  The determination unit 41 transmits to the reception unit 13 a message that includes the same editing content as the editing content included in the message that triggered the activation of the agent program 4. As a result, the reception unit 13 notifies the agent activation unit 14 of the reception of the message again, so that the agent activation unit 14 restarts the agent program 4 (step S16).

  The restarted agent program 4 opens a document reflecting the edited content and starts editing (step S17). The determination unit 41 of the restarted agent program 4 determines whether or not the edited content of the agent program 4 conflicts with the edited content of the edit receiving unit 11 before saving the document reflecting the edited content (step S18). ). The determination unit 41 of the restarted agent program 4 determines that the edited content is not in conflict because the timing for saving the edited content is delayed. The edit storage unit 42 stores the document reflecting the edited content (step S19).

  In the example of FIG. 4, the case where the editing contents of the client device 2 and the agent program 4 compete is described. However, the operation of the above-described agent program 4 is the same even when the content of editing conflicts between the two agent programs 4. Further, the operation of the agent program 4 described above is the same when the editing contents conflict among three or more editing subjects (client device 2 or agent program 4).

  FIG. 5 is a flowchart for explaining a case where a document is edited via the edit receiving unit 11 in the document management system 10 according to the first embodiment. The client device 2 accesses the document management DB 16 of the storage unit 15 via the edit reception unit 11 (step S21). The client device 2 opens the document in the document management DB 16 (step S22). The client device 2 edits the document (step S23). The client device 2 stores the document (step S24). The client device 2 closes the document (step S25).

  FIG. 6 is a flowchart for explaining a case where a document is edited via the proxy editing accepting unit 12 in the document management system 10 according to the first embodiment. The client device 2 transmits a message including the edited content to the receiving unit 13 of the proxy editing accepting unit 12 (step S31).

  The proxy edit accepting unit 12 starts the agent program 4 upon receipt of the message (step S32). The agent program 4 accesses the document management DB 16 in the storage unit 15 (step S33). The agent program 4 opens the document in the document management DB 16 (step S34). The agent program 4 edits the document (step S35).

  The determination unit 41 of the agent program 4 determines whether the edited content is in conflict with the edited content by the edit receiving unit 11 before the edited storage unit 42 stores the edited content (step S36). If the editing contents are in conflict (step S36, Yes), the transmission unit 43 of the agent program 4 receives a message including the same editing contents as the editing contents included in the message that triggered the activation of the agent program 4. It transmits to the part 13 (step S37). If there is no conflict in the editing contents (No in step S36), the editing storage unit 42 of the agent program 4 stores the document reflecting the editing contents (step S38). The edit storage unit 42 of the agent program 4 closes the document reflecting the edited content (step S39).

  According to the document management system 10 of the present embodiment, even if the content of editing conflicts when the agent program 4 stores a document, the editing content of the agent program 4 can be stored in real time.
