Description

  The present invention relates to file management for files such as documents that can be accessed by one or more users in a document sharing system (herein, generically referred to as document files), and more particularly to logical deletion of document files in a document sharing system. It is.

  Conventionally, when a document file shared in a document sharing system is logically deleted, the file is stored in a folder for logical deletion (hereinafter referred to as a recycle bin) that can be accessed only by the operating user and not shared with other users. I was going to move. Note that the logical deletion moves the file to the trash which is a specific folder in this way, so that the document file remains on the storage device.

  In contrast to the conventional general technique, the technology disclosed in Patent Document 1 provides two types of recycle bins, a local recycle bin and a shared recycle bin on the server, so that logical deletion can be performed. The user will use it arbitrarily. That is, the user needs to use the two types of trash bins consciously (see FIG. 7).

JP 2002-366410 A

  In the above conventional method, users other than the user who moved the document file to the trash box cannot access the trash box, and thus cannot access the file moved to the trash box. Therefore, there is a problem that only the user who has moved the document file to the trash can restore (restore) the document file once moved to the trash to the normal folder (folder other than the trash can).

  On the other hand, in the technique disclosed in Patent Document 1, since a local trash box and a shared trash box on a server are provided, the user must consciously use these two types of trash boxes. That is, there is a problem in terms of convenience.

  The present invention has been made in view of the above problems, and is for a document sharing system that allows a person other than the user who moved a document file to the trash box to restore the document file under predetermined conditions. The purpose is to provide the technology. It is another object of the present invention to provide a technique for a document sharing system capable of logical deletion with the same usability as a conventional trash box (apparently as one trash box).

In order to solve the above-described problem, a first invention is a document management method in a document sharing server provided on a computer network, and specifies a document file stored in a storage device provided in the document sharing server. In the file management process, in response to an instruction to logically delete a document file by the user, (1) the specific user management information has instructed a logical deletion. If the authority for the designated document file is indicated only to the user, the designated file is moved to the first logical deletion storage area in the storage device that can be accessed only by the user. (2) The specific user management information indicates the authority for the designated document file for a plurality of users. Expediently, and performing a logical deletion of the document file by moving the plurality of users specified in the second logical deletion memory area in the storage device that is accessible file.

  Further, according to a second invention, in the first invention, in the file management step, the authority for the document file logically deleted is given to a single user by the specific user management information. If it is indicated, the single user is allowed to freely return the document file to the state before the logical deletion.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, in the file management step, an authority is given to a plurality of users for the document file that has been logically deleted by the specific user management information. If the user who has the authority to the document file is a user other than the user who has executed the logical deletion, on the condition that the approval of the user who has executed the logical deletion is received, It is characterized by allowing the file to be returned to the state before the logical deletion.

  According to a fourth aspect, in the first to third aspects, the authority is an access right to a document file.

  According to a fifth invention, in the first to third inventions, the authority is an authority determined based on an access state with respect to the document file.

  The sixth invention is realized as a program comprising a group of instructions for causing a server computer to execute the document management methods of the first to fifth inventions.

  The seventh invention is realized as a computer-readable recording medium recording the program of the sixth invention.

  The eighth invention is a document sharing server provided on a computer network, and performs file management according to specific user management information for a document file stored in a storage device provided in the document sharing server. Control means, wherein the control means responds to an instruction to logically delete a document file received by the user via the computer network. (1) The specific user management information indicates to the user who has instructed the logical deletion. In contrast, in the case of indicating the authority for the designated document file, the designated file is moved to the first logical deletion storage area in the storage device accessible only by the user, (2) When the specific user management information indicates authority for a document file designated for a plurality of users , And it performs the logical deletion of the document file by moving the plurality of users specified in the second logical deletion memory area in the storage device that is accessible file.

  The ninth invention is a document sharing system comprising a document sharing server and a computer terminal provided on a computer network, wherein the document sharing server is stored in a storage device provided in the document sharing server. Control means for performing file management on the document file in accordance with specific user management information, wherein the control means responds to a logical deletion instruction of the document file received from the computer terminal by the user. If the user management information indicates only the user who has instructed the logical deletion, the first management information in the storage device that can be accessed only by the user. The specified file is moved to the logical deletion storage area, and (2) the specific user management information is sent to a plurality of users. If the specified file is indicated, the logical file is moved by moving the specified file to the second logical deletion storage area in the storage device accessible by the plurality of users. The computer terminal accepts an instruction for logical deletion of the file by moving the file in accordance with the user's operation to the trash folder that is displayed only on the GUI screen. It transmits to a document sharing server, It is characterized by the above-mentioned.

  According to the present invention, even a user other than the user who moved the document file to the trash box (logical deletion storage area) and deleted it can return the document file to the normal folder (that is, restore it). Convenience can be improved. Further, when returning a document from the recycle bin to a normal folder, the user's intention is also respected because it is approved by the user who actually performed the logical deletion. Further, when a user moves a document file to the trash box and deletes it or restores it from the trash box, logical deletion and restoration can be performed without being aware of the two types of trash boxes.

It does not matter.

  FIG. 9 shows a processing flow inside the document sharing system when the user of the document sharing system gives an instruction to delete a document to the trash box.

In step S901, a user who has the right to delete a specified document deletes the document in the trash box.
S902 represents a determination as to whether or not the user has the authority to delete a document when the user instructs to delete the document in the trash box in S901. If the user has the authority to delete the designated document, the process proceeds to step S903. If the user has no authority, the process cannot be performed because the document cannot be moved to the trash box.

  In S903, if it is determined in S902 that the user has the authority to delete the specified document in the trash, it is further determined whether or not another user (one or more) has been given access to the document. Represents processing. If the access right is given to another user, the process proceeds to step S904, and if the access right is not given to another user, the process proceeds to step S905.

S904 is processing performed when it is determined in S903 that the specified document is given access rights to other users, and the specified document is moved to a shared trash box accessible to all users. Represents the processing to be deleted.
S905 is processing performed when it is determined in S903 that the designated document does not have access rights to other users. In this case, since the access right is the same as that given only to the user, the specified document is moved to and deleted from the user's private trash box.

  The shared trash bin and the dedicated trash bin may have a configuration in which a dedicated temporary storage area is provided in the information storage device 310, or a common temporary storage area is provided and a flag (for example, the trash box type 1406 shown in FIG. 14) is used. Then, it may be logically divided and managed.

  FIG. 10 shows a processing flow performed by a user when a user of the document sharing system gives an instruction to browse a document file to which an access right is given.

S1001 represents an operation in which a user accesses a folder through a GUI on the screen in order to view an arbitrary document.
S1002 represents a step of determining whether or not a desired document exists in the folder accessed by the user in S1001. If there is a document desired by the user, the process proceeds to S1010, and if not, the process proceeds to S1003.
S1003 represents an operation when a document desired by the user does not exist in the designated folder in the determination of S1002. In that case, since it may be deleted in the recycle bin, the recycle bin is accessed.

  S1004 represents a determination as to whether or not a desired document exists in the trash box by accessing the trash box in the process of S1003. If it exists, the process proceeds to S1005, and if it does not exist, the process proceeds to S1011. As shown in FIG. 7 and FIG. 8, the recycle bin referred to here is both a shared recycle bin accessible to all users and a dedicated recycle bin accessible only to the user, but a terminal used by the user. On the GUI, it is displayed as one trash can as described above.

S1005 represents a determination of whether the document is in the exclusive trash box or in the shared trash box when the desired document exists in the trash box in the determination of S1004. This determination is made internally by the system and does not require the user's determination.
If this determination determines that the document does not exist in the shared recycle bin, this indicates that the document exists in the private recycle bin, so this document is recognized as deleted by the user in the dedicated recycle bin, The process proceeds to S1009. If it is determined in this determination that the document exists in the shared recycle bin, this indicates that the user or another user has deleted the recycle bin, and therefore the process S1006 for determining who is deleted in the recycle bin. Proceed to

  S1006 is a determination performed when it is determined in S1005 that a desired document exists in the shared trash, and the user who deleted the document in the trash is a user other than the user (here, the user who started S1001). This is a process for determining whether or not there is. If the user who deleted the document in the trash box is the user, the process can return to the normal folder from the trash box, and the process advances to step S1009.

  If the user who deleted a document in the Recycle Bin is a user other than that user, the user needs approval to return the document from the Recycle Bin to the normal folder, so the user who deleted the document in the Recycle Bin is approved. The process proceeds to S1007 for making a request. The user who deleted the document in the trash box is determined by referring to data in the deleted document / folder information storage table 1400 shown in FIG. 14 to be described later. A configuration example of this table will be described in detail with reference to FIG. Describe.

  In S1007, since it is determined in S1006 that a user other than the user has deleted the document in the recycle bin, the user who deleted the document in the recycle bin returns the document to a normal folder in order to view the document. This represents processing (to be described later) for requesting approval.

  S1008 represents a determination as to whether the approval request in S1007 has been approved. If it is not approved, it is impossible to view the document, and this processing flow ends. If approved, the process proceeds to S1009 to perform the next process.

  S1009 is a process in the case where it is determined in S1008 that the approval request in S1007 has been approved, and represents an operation of returning from the recycle bin to a normal folder in order to view the document. If the user who moved and deleted the file to the trash box in the determinations of S1005 and S1006 is the user, the user can return the document from the trash box to a normal folder without performing an approval request in S1007.

  S1010 is a process that can be performed when the desired document exists in the normal folder according to the determination in S1002 or when the document is returned from the recycle bin to the normal folder by the operation of S1009, and the user browses the desired document. Is possible.

  S1011 is a determination performed when a desired document does not exist in the trash box in the determination of S1004, and represents a determination of whether or not another folder has been found and found. If no other folder is found, the process returns to S1001 to access another folder. If the desired document is not found even after searching for another folder, the process proceeds to S1012.

  Step S1012 represents a process performed when it is determined in step S1011 that a desired document is not found in another folder. In this case, the document has been completely deleted (physical deletion) or the user has no access right to the document, and it becomes impossible to view the desired document, and this processing flow ends. .
