  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block configuration diagram showing an embodiment of a document management system according to the present invention. FIG. 1 shows a system configuration example in which a document management apparatus 30 and a client 20 in this embodiment are connected by a network 12.

  FIG. 2 is a hardware configuration diagram of a computer forming the document management apparatus 30 in the present embodiment. In the present embodiment, the server computer forming the document management apparatus 30 can be realized with a general-purpose hardware configuration that has existed in the past. That is, as shown in FIG. 2, the computer is provided with a CPU 1, a ROM 2, a RAM 3, an HDD controller 5 connected to a hard disk drive (HDD) 4, a mouse 6 and a keyboard 7 provided as input means, and a display device. An input / output controller 9 for connecting each display 8 and a network controller 10 provided as a communication means are connected to an internal bus 11.

  Although there may be a difference in performance, since the client 20 is also a computer, its hardware configuration can be illustrated as in FIG.

  Returning to FIG. 1, the document management apparatus 30 includes an access right determination unit 31, an approval unit 32, an information management unit 33, and a document management unit 34. The document management apparatus 30 further includes a document storage unit 41, a user group information storage unit 42, a document information storage unit 43, a document status information storage unit 44, a group relation information storage unit 45, and access right information as means for storing various types of information. A storage unit 46, an approver authority information storage unit 47, an approver information storage unit 48, and a weight correction information storage unit 49 are provided.

  The access right determination unit 31 operates as a weight specifying unit and an access right specifying unit. In response to a document access request sent from the client 20 in response to a user operation, the presence / absence of the access right of the designated document and the access If there is a right, specify the type and reply. The approval unit 32 operates as an approver specifying unit and a weight adjusting unit, and determines whether or not the process is approved for a document processed by the user in response to an approval request sent from the client 20 in response to a user operation. And return the result. The information management unit 33 performs information management of the storage units 42 to 50 such as addition, update, and deletion of information by exchanging information with the user or an operating system and other computers. Specific processing contents will be described later. An electronic document is stored in the document storage unit 41, but the document management unit 34 stores and stores a document in response to a document processing request sent from the client 20 in response to a user operation. The document stored in the document storage unit 41, such as update and deletion, is managed.

  Next, the data structure of each storage means will be described. The document storage unit 41 stores the digitized document as described above. In the user group information storage unit 42, correspondence relationships between users who can be users of the system and departments, departments, etc. (hereinafter collectively referred to as “groups”) to which each user belongs are registered. Specifically, the identification information of the group is registered in association with the user ID belonging to the group. Each group is composed of one or more members. One user may belong to a plurality of groups.

  FIG. 3 is a diagram showing a data configuration example of the document information storage unit 43 in the present embodiment. The document information stored in the document information storage unit 43 includes a document ID that is document identification information, a document name of the document, an authority holding group that owns the document, and a storage location that specifies the storage destination of the document Information is configured in association with each other. In this embodiment, since the group to which the owner belongs rather than the individual document owner is treated as the document owner, the authority holding group, that is, the group to which the individual document owner belongs belongs as information for specifying the document owner. Identification information is set. In the present embodiment, the group name is used as the group identification information. Since one user may belong to a plurality of groups, an appropriate group is set in the document information by the owner or information manager.

  FIG. 4 is a diagram showing a data configuration example of the document state information storage unit 44 in the present embodiment. The document status information stored in the document status information storage unit 44 is configured by associating a document status with a document ID. Since a system for managing documents is used for a certain purpose, the types of documents to be managed in this system are limited to some extent. In addition, when a document to be managed is narrowed down to some extent, the stage for handling the document is also determined to some extent. For example, a document such as a functional specification generally goes through a plurality of stages such as a draft creation stage, a review stage, and an approval waiting stage until the creation is completed. In this embodiment, a stage where a document is placed is referred to as a document state, and can be managed using the document state information storage unit 44. The update of the document state is performed by the information management unit 33 operating in conjunction with the document application.

  FIG. 5 is a diagram showing a data configuration example of the group relationship information storage unit 45 in the present embodiment. The group relationship information stored in the group relationship information storage unit 45 is composed of a document type, an authority holding group, a related group, and a weight. The authority holding group is the owner of the document as described above, and the related group is the group to which the document access requester belongs. In the present embodiment, like the document owner, the document access requester is handled as a group rather than an individual. The weight is a set value of the weight given to the document access requester. According to the setting example shown in FIG. 5, when a development 2G member accesses a document whose development 1 group (G) is the owner and whose document type is a functional specification, the weight is 1000 and the development 3G member The access weight is 100, and the quality control G member access is 10. That is, different weights can be given to the same document depending on the document access requester.

  FIG. 6 is a diagram showing a data configuration example of the access right information storage unit 46 in the present embodiment. The access right information stored in the access right information storage unit 46 is composed of a document type, a document state, a weight condition, and an access right. The weight to be given to the document access requester is specified by referring to the group relation information in the process of the access right determination process to be described later. In addition to the document type and the document state, the specified weight d is the weight. Access right information corresponding to the conditional expression specified by the condition is specified from the plurality of access right information registered in the access right information storage unit 46. The access right is a type of access right set for the document access requester. In the present embodiment, as the types of access right, the access right managed by the operating system (normal access right) and the conditional access right (temporary access right) that permits document access only after approval by the approver is handled. To. In this embodiment, the access right information registered at the upper position is preferentially adopted. In FIG. 6, “*” is access right information that is adopted when it does not correspond to the upper access right information. The same applies to various types of information described below.

  FIG. 7 is a diagram showing a data configuration example of the approver authority information storage unit 47 in the present embodiment. The approver authority information stored in the approver authority information storage unit 47 is composed of a document type, a weight condition, and an approver-required authority. The approver-required authority is a level of authority required by the certifier. In this embodiment, it is shown that the authority level is higher as the level value is larger. The lowermost information means that there is no approver, that is, no approver for the document is set, and as a result, there is no access right to the document.

  FIG. 8 is a diagram showing a data configuration example of the approver information storage unit 48 in the present embodiment. The approval information storage unit according to the present embodiment is configured by the approver authority information storage unit 47 and the approver information storage unit 48. The approver information stored in the approver information storage unit 48 includes the document type, The authority holding group, the approver, and the approver-required authority are combined. The approver is specific information of the approver for the requested document. The lowermost information is not referred to in the normal process, but has no approval authority (= 0), that is, there is no approver authority, which means that the approver can be anyone.

  FIG. 9 is a diagram showing a data configuration example of the weight correction information storage unit 49 in the present embodiment. The weight correction information stored in the weight correction information storage unit 49 includes a document type, a document state, an approval result, and a weight addition / subtraction value. The approval result is an approval result by the approval unit 32. The weight addition / subtraction value is an addition / subtraction value set in order to change the weight value set in the group relation information.

  Each component 31 to 34 in the document management apparatus 30 is realized by a cooperative operation of a computer that forms the document management apparatus 30 and a program that operates on the CPU 1 mounted on the computer. The storage units 41 to 49 are realized by the HDD 4 mounted on the document management apparatus 30.

  In the present embodiment, the storage unit described above is used. However, the configuration of the storage unit is not limited to the above example, and the data items may be appropriately integrated or divided.

  In FIG. 1, the document management apparatus 30 is illustrated as being realized by a single computer for convenience, but may be configured by a plurality of computers such as a database server.

  Next, the configuration of the client 20 will be described.

  The client 20 includes a document access request unit 21, a document processing unit 22, an approval request unit 23, and an edited document holding unit 24. The document access request unit 21 sends an access request for a document designated in accordance with a user operation to the document management apparatus 30, and acquires the type of access right returned in response to the request. The document processing unit 22 performs document processing such as browsing and editing on the document. When a document is updated by editing, the edited content is written in the edited document holding unit 24 and temporarily held. The approval request unit 23 sends an approval request request for the edited document to the document management apparatus 30 and receives an approval result returned in response to the request.

  Each component 21-23 in the client 20 is implement | achieved by cooperation operation | movement of the computer which forms the client 20, and the program which operate | moves by CPU1 mounted in the computer. The edited document holding unit 24 is realized by the HDD 4 installed in the client 20. Although only one client 20 is illustrated in FIG. 1, a plurality of client computers having the same configuration may be connected to the network 12.

  Further, the program used in this embodiment can be provided not only by communication means but also by storing it in a computer-readable recording medium such as a CD-ROM or DVD-ROM. The program provided from the communication means or the recording medium is installed in the computer, and various processes are realized by the CPU of the computer sequentially executing the installation program.

  Next, the operation in this embodiment will be described. First, an example of an access right determination process for determining the type of access right to be granted to a document access requester and identifying an approver who approves an update to a document when the access right to be granted is a temporary access right is shown in FIG. This will be described with reference to the flowchart shown in FIG.

  The document access request unit 21 in the client 20 sends a document access request designated by the user and a document access request designated by the user according to a predetermined operation by the user who wants to access the document management apparatus 30. Send to. When receiving the document access request sent from the client 20 (step 101), the access right determination unit 31 in the document management apparatus 30 first checks whether there is a normal access right (step 102). Specifically, it is checked whether or not the normal access right is set for the document by referring to the attribute information of the document based on the sent document ID of the document designated as the access target. Note that the attribute information related to the normal access right may be managed by a storage unit such as access right information, or may be added to the document stored in the document storage unit 41. If the normal access right is granted to the document access requester as the access right for the document (Y in step 103), the access right determination unit 31 indicates that the normal access right is set. A reply is made to the original client 20 (step 112).

  On the other hand, when the normal access right is not granted to the document access requester (N in step 103), the access right determination unit 31 searches the user group information storage unit 42 based on the user ID of the document access requester. A group to which the document access requester belongs is extracted, and a group list to which the document access requester belongs is created based on the extracted group name (step 104). If the group to which the document access requester belongs is not extracted (N in step 105), the access right determination unit 31 determines that the document access requester does not have access to the document. A reply is made to the original client 20 (step 113). When a group is extracted (Y in Step 105), the access right determination unit 31 searches the document information storage unit 43 based on the document ID of the document to be accessed, and acquires the document type and authority holding group of the document. To do. Then, the weight to be given to the document access requester is specified by searching the group relation information storage unit 45 based on the acquired document type and authority holding group and the group (related group) included in the group list (step) 106). When a plurality of groups are registered in the group list, a plurality of weights are extracted. In this case, the maximum weight is selected as a weight to be given to the document access requester.

  Subsequently, the access right determination unit 31 acquires the document state of the document by searching the document state information storage unit 44 based on the document ID of the document to be accessed, and accesses registered in the access right information storage unit 46. From the right information, access right information that matches the acquired document state and the acquired document type and that the weight specified in step 106 satisfies the weight condition is specified. The type of access right set in the access right information specified in this way is set for the document access requester (step 107).

  As described above, the access right set for the document access requester is determined. When the access right set here is the normal access right (Y in step 108), the access right determination unit 31 sets the normal access right. This is returned to the document access requesting client 20 (step 112). If the access right to be set is not a normal access right (N in Step 108) and is not a temporary access right (N in Step 109), the access right determination unit 31 sends the document access requester to the document. Is returned to the client 20 as the document access request source (step 113).

  If the access right to be set is a temporary access right (Y in Step 109), the access right determination unit 31 continues to specify an approver for document access as follows (Step 110). That is, the approval is performed by selecting the approver authority information that satisfies the weighting condition of the document type of the document to be accessed and the weight specified in step 106 from the approver authority information registered in the approver authority information storage unit 47. The required authority If there is no corresponding approver authority information, or if approver authority information with “*” set as the weight condition is selected, it is assumed that there is no approver, that is, there is no access right. The same processing may be performed. When the approver required authority is specified, the access right determination unit 31 searches the approver information storage unit 48 based on the specified approver required authority, the acquired document type, and the authority holding group, thereby selecting the approver. Identify.

  When the approver is specified as described above, the access right determination unit 31 returns a message indicating that the temporary access right has been set and the specific information of the approver to the document access request source client 20 (step 111).

  In the present embodiment, the document type and document state of the document to be accessed are identified as described above, and the relationship between the document owner (authority holding group) and the group to which the document access requester belongs is specified. The access right set for the document access requester is dynamically determined according to the relationship with the weight. In particular, in the case of a temporary access right that permits access to a document only after approval, the weight given to the document access requester is large, which is closer to the authority holding group based on the document type of the document to be accessed. It seems that there is a relationship. In other words, the group relationship information is set so that a large weight is given to the document access requester having a close relationship. A relatively higher level of authority may be granted to closely related document access requesters. The document access requester who has been given high authority by giving such a large weight is a relatively reliable document accessor. In other words, since the reliability of the document access requester itself is high, the level of the approver itself does not need to be relatively high. On the other hand, if it is an access request from a document access requester with relatively low reliability, it is considered that a relatively high level of approval is required. As can be understood by referring to the setting contents of the approver authority information included in the approver authority information and the approver information, in the present embodiment, a relatively large weight is given based on such an idea. Document access requesters who have a relatively low authority level are selected as approver due to the high reliability of the document access requester itself. For the access requester, approver is required for each approver authority information and approver information so that a person with a relatively high authority level is selected as an approver because the reliability of the document access requester itself is low. Permission is set. In this embodiment, different approvers can be designated according to the weights.

  When the access right to the document is specified by the above access right determination processing, the document processing unit 22 in the client 20 edits the access target document extracted from the document storage unit 41 in response to an operation instruction from the user. And other document processing. Of course, access is not possible if there is no access right. When the normal access right is set, the document processing unit 22 performs document processing within the normal access right setting range as before. Here, in the case where the temporary access right has been set and the document editing is completed and the document is to be saved for update, the document processing unit 22 temporarily stores the edited document by writing it in the edited document holding unit 24. To do. Then, the approval request unit 23 sends an approval request request including the document ID of the document, the specific information of the approver, and the user ID of the approval requester to the document management device 30. Executed. An example of this approval process will be described with reference to the flowchart shown in FIG.

  When the approval unit 32 in the document management apparatus 30 receives the approval request request sent from the client 20 (step 121), the approval unit 32 includes information on the target document and the approval requester in response to the request. The designated approver is notified (step 122). As a notification method, various methods such as notification by e-mail, display on a login screen, and a pop-up screen for approval can be considered. In response to the approval request, the approver designates whether to approve document access. When the approval result is received (step 123), the approval unit 32 specifies the document type and the document status corresponding to the document ID included in the approval request by referring to the document information and the document status information. Then, the weight addition / subtraction value is acquired by searching the weight correction information storage unit 49 based on the specified document type and document state and the accepted approval result. Then, the relevant group relation information specified based on the user ID of the approval requester included in the approval request and the document type and authority holding group corresponding to the document ID is specified and specified. The weight set in the group relation information is adjusted by the acquired weight addition / subtraction value (step 124).

  In this way, when the weight is updated based on the approval result, the approval unit 32 returns an instruction to reflect the editing content to the approval request request source when the approver approves the document editing (Y in step 125). (Step 126). On the other hand, if the approver does not approve the document editing (N in step 125), an instruction to discard the editing contents is returned to the approval request request source (step 127).

  In the client 20, when the approval request unit 23 receives an instruction to reflect the edited content, the document processing unit 22 reflects the edited content temporarily stored in the edited document holding unit 24 in the document, and then the document is stored in the document storage unit. 41 is registered. On the other hand, when the approval request unit 23 receives an instruction to reflect the edited content, the document processing unit 22 deletes the edited content temporarily stored in the edited document holding unit 24 without reflecting it in the document.

  In the present embodiment, the approval process has been described by taking editing as an example. However, the approval process is similarly executed in processes other than editing.
