Description

  The present invention relates to an electronic information group sharing server apparatus and a computer program for sharing an electronic information group such as a file / folder among a plurality of client apparatuses.

A server device in which a plurality of files are stored and a plurality of client devices that can access the server device are connected via a network, and a predetermined file in the server device is accessed by each client device for reference, update, etc. A file sharing system that can be used has been put into practical use (for example, see Patent Document 1).
In such a file sharing system, whether or not each client device can access a file in the server device is managed as follows.

That is, the above-described files are grouped into a plurality of groups, and are given to the files as group information. Each file is given access restriction information such as whether the file can be updated. These group information and access restriction information are registered in the server device for each file as file management information. In addition, a group to which the user belongs is registered as group information for each user in the server device. When an access request to the stored file is input, the server device is based on the user group information related to the access request. Whether access is possible is determined. If access is possible, an access mode such as reference / update is further determined based on the access restriction information.
Therefore, the user can access files in the group to which the user belongs, but access to files belonging to other groups is limited.
JP 2002-149466 A

  In such a file sharing system, when the group to which a user belongs is changed, such as user relocation, department consolidation, organization consolidation / division, etc., the file in the group before the change can also be accessed in the group after the change. It is necessary to update the group information of each file that needs to be updated to the group information of the group after the change. In the above-described conventional server device, such an update operation is performed by an administrator who manages the server device. However, the update operation is complicated, and there is a risk that update mistakes frequently occur.

  The present invention has been made in view of such circumstances, and when the group to which the user belongs is changed, the burden associated with updating the management information of the target file (electronic information group) is reduced, and an update error occurs. An electronic information group sharing server device and a computer program are provided.

  An electronic information group sharing server device according to the present invention includes an electronic information group database capable of storing a plurality of types of electronic information groups, identification information for identifying a user, and first group information relating to a group to which the user belongs. Electronic information group stored in the electronic information group database including a user management database storing a plurality of user management data, type information of the electronic information group for each electronic information group, and second group information to which the electronic information group belongs An electronic information group management database for storing electronic information group management data having storage location information relating to the location, identification information and access restriction information for the electronic information group, and storing the electronic information stored in the electronic information group database The electronic information group can be shared by making the information group accessible from a plurality of client devices. In the electronic information group sharing server apparatus, when the first group information is updated, the second group information is updated based on the electronic information group management data and the user management data related to the updated first group information. Electronic information group management data selection means for selecting electronic information group management data to be selected from the electronic information group management database, and output means for outputting the selected electronic information group management data.

  The electronic information group management data selection means of the electronic information group sharing server device described above, when the first group information related to the group to which the user belongs is updated, the type information of the electronic information group for each electronic information group, the electronic information An electronic device having storage location information (for example, full path) relating to the location of the electronic information group stored in the electronic information group database, including the second group information to which the group belongs, identification information such as a user ID, and access restriction information for the electronic information group Based on the information group management data and the updated user management data relating to the first group information, electronic information group management data for which the second group information should be updated for the user is selected from the electronic information group management database.

  The output means outputs the electronic information group management data selected by the electronic information group management data selection means to the outside. The output timing may be, for example, when the identification information related to the updated first group information is input from a predetermined client device immediately after the update of the first group information.

  In this way, when the group to which the user belongs is changed and the first group information related to the user's affiliation is updated, the electronic information group in which the second group information should be updated for the user by the electronic information group management data selection means Since the management data is selected from the electronic information group management database, the electronic information group management data to be updated is selected without depending on the administrator, and the complexity required for the update operation is eliminated.

  The output means described above outputs the update permission information to the corresponding client device. Then, after the update permission information is output to the client device, when update permission information is input from a predetermined client device corresponding to the update permission information, the updating means is based on the input update permission information. The corresponding second group information is updated to the same group information as the updated first group information.

  In this way, the approval information indicating whether or not the second group information of the selected electronic information group management data may be updated is output to the corresponding client device, and the update permission information is input from the client device by the user. In this case, since the corresponding second group information is updated, occurrence of an update error is prevented.

  Incidentally, the means for determining by the electronic information group management data selection unit described above determines whether or not the first group information has been updated. Such a determination can be made, for example, by giving information related to the group change from another server device that manages the group to which the user belongs. The determination can also be made by the user or the administrator of the electronic information group sharing server device directly inputting the update request for the first group information. Further, it is possible to make a determination by providing means for managing data in the user management database and detecting the update of the first group information by the means.

  When it is determined that the first group information has been updated, the means for acquiring user management data acquires the user management data related to the updated first group information from the user management database, and acquires electronic information group management data Acquires electronic information group management data related to identification information included in the acquired user management information from the electronic information group management database.

Then, the extracting means extracts electronic information group management data for updating the second group information from the acquired electronic information group management data based on the type information and the access restriction information in the acquired electronic information group management data. To do. For example, a file that can be accessed without limitation, a folder that can access all the stored files without limitation, and the like are extracted.
As a result, it is possible to reliably extract an electronic information group having a high user-accompanying property.

Further, each electronic information group management data described above is given presence / absence of a group to which each corresponding electronic information group should belong or third group information including the group.
And the said extraction means corresponds to the group of the 1st group information in which the information of the group which should belong, for example, the electronic information group management data provided as the 3rd group information, the group of the 3rd group information was changed The electronic information group management data to be extracted is extracted from the electronic information group management data acquired as described above.
As a result, it is possible to individually extract electronic information groups having high user accompaniment.

(First embodiment of the present invention)
FIG. 1 is a block diagram showing a main configuration of a system including a file (electronic information group) sharing server device 1 according to the present invention. In FIG. 1, reference numeral 3 denotes a user accessing a file in the file sharing server device 1. Client device for

And the file sharing server device 1 are interconnected via the network N, and the file sharing system S is constructed.

  The file sharing server device 1 has a user management database (DB) 13 in which user management data for managing information related to users is stored, and a plurality of files and / or files given from the client devices 3, 3,. Is stored in a file database (DB) 14 storing a folder storing files, and a file management database (DB) 15 storing data for managing access to each file. Stored user management data, files and / or folders (electronic information group) stored in the file database 14, registration / update management of file management data stored in the file management database 15, and stored in the file database 14 Access control for each file Management unit 12 to perform is provided.

  FIG. 2 is a table showing an example of user management data stored in the user management database 13 shown in FIG.

  As shown in FIG. 2, as user management data, a user ID assigned to each user and for identifying each user is registered, and for each user ID, the name of the user and the user currently belongs. Information such as “affiliation (first group information)” indicating the branch name and “old affiliation” indicating the branch name that belonged immediately before is registered.

  In the example shown in FIG. 2, the user whose user ID is “U001” belongs to “Fukuoka branch”, and the former affiliation is “Kagoshima branch”. You can see that has changed. On the other hand, the user whose user ID is “U002” has the affiliation “Fukuoka branch” and the old affiliation “None”, so it is understood that the user has not been transferred.

  FIG. 3 is a table showing an example of file management data stored in the file management database 15 shown in FIG.

  As shown in FIG. 3, as file management data, each file / folder (type information) stored in the file database 14 has its name (file name, folder name) and group information related to the affiliation of the file / folder ( (2nd group information) including the full path indicating the location, the user right (access restriction information) indicating whether or not the user of each user ID can access the file / folder and the access mode, and management data related to the file / folder Regional information (third group information) to be used as an index of updating is set.

  In the example illustrated in FIG. 3, as the above-described user rights, “none” in which access to the file or folder is denied, “update rights” that can update / delete the file or folder, the file or “Ownership” that allows the folder to be updated / deleted / granted and updated, and “reference” that allows the file or folder to be referenced but not updated / deleted are set.

Further, in the example shown in FIG. 3 as the regional information mentioned above, “Fukuoka” related to the Fukuoka branch, “Kumamoto” related to the Kumamoto branch, “Kagoshima” related to the Kagoshima branch, and “None” not related to any branch. Is set.
Such area information is set as an attribute of each file and each folder, and “None” is set in the initial state. However, the user or the administrator of the file database 14 can set in advance as necessary. Select and set the required area from the defined area.

  When an access request to a file or folder stored in the file database 14 is given from an arbitrary client device 3 to the client interface unit 11 of the file sharing server device 1 via the network N, the client interface unit 11 sends the access request. This is given to the management unit 12. The access request includes information such as the user ID of the user who sent the request, the file name or folder name to be requested, and the management unit 12 stores the information included in the access request in the user management database 13. Based on the user management data and the file management data stored in the file management database 15, an access mode such as whether or not the corresponding file or folder can be accessed and whether or not update is possible is determined. If access is impossible, access refusal information is transmitted from the client interface unit 11 to the originating client device 3, and if access is possible, access in the determined access mode is permitted.

On the other hand, apart from such a file sharing system S, a personnel server device 4 for managing personnel information including the user ID of each user and the information of the user's assignment destination is provided.

As shown in FIG. 6, the file selection unit 21 determines whether or not there is file management data in which the type information is a file and the ownership is set as access restriction information for each acquired file management data ( (First rule) is determined (step S41), and if there is file management data in which the type information is a file and the ownership is set as the access restriction information, each corresponding file management data is extracted (step S45). ).

  Next, the file selection unit 21 is the file management data for which the type information is a folder and the ownership is set as the access restriction information for each file management data not selected in step S41, and is stored in the folder. It is determined whether or not all files / folders that are set with ownership or update right exist (second rule) (step S42), and file management data relating to the corresponding folder exists. If so, each corresponding file management data is extracted (step S45).

  Further, the file selection unit 21 selects, for each file management data not selected in step S42, the region of the same group as the group to which the type information is a file and the user management data is updated (first group information). It is determined whether or not file management data for which information (third group information) is set exists (third rule) (step S43). If file management data relating to the corresponding folder exists, the process proceeds to step S45. To extract each corresponding file management data.

  Further, the file selection unit 21 has file management data in which the type information is a file and “none” is set as the region information (third group information) for each file management data not selected in step S43. (4th rule) is judged (step S44), and when the file management data concerning a corresponding folder exists, it moves to step S45 and each applicable file management data is extracted.

  As shown in FIG. 7, such a file management data update program is read into the server device and causes the server device to function as the file (electronic information group) shared server device 1 as described above.

  FIG. 8 is a table for explaining an example of the selection result of the file management data. FIG. 8 shows the result of applying the first rule to the fourth rule described above for each file management data shown in FIG.

  When it is determined whether or not each of the file management data shown in FIG. 3 corresponds to the first rule to the fourth rule, as shown in FIG. 8, the file management data related to the first to third rows from the top, and Since the file management data related to the fifth and eighth lines from the top does not correspond to any of the rules described above, none is selected.

  On the other hand, the file management data according to the fourth line from the top corresponds to the second rule, and the file management data according to the same sixth line and the seventh line correspond to the first rule and the fourth rule, respectively. The file management data according to the ninth line from the top corresponds to the third rule. Accordingly, all of these file management data are selected by the file selection unit 21.

  When the selection of the corresponding file management data is completed in this way, the file selection unit 21 asks the corresponding user to approve the update of the second group information included in the selected file management data including the selected file management data. Update approval information is created (step S6), and the created update approval information is output from the client interface unit 11 to the client device 3 of the corresponding user (step S7).
