Description

  The present invention relates to a document management apparatus, a document management system, a document management program, and a document management method.

  A financial institution such as a bank reads a document such as a form with a scanner, converts it into an electronic document, and stores it. Not only financial institutions but also electronic documents are widely used for easy handling as information.

  When a digitized document is revised such as when data is added, deleted, or updated, a new version is added while saving the document before the revision to facilitate management of the update history. For this reason, the amount of data in an electronic document tends to be enormous, and a document management system that makes it easy to handle these has been proposed (for example, see Patent Document 1).

JP 2008-77581 A

  The document management apparatus does not delete or update the old version document by adding a new version document at every revision. Therefore, the document management apparatus has an advantage that once the old version of the document is backed up, there is no change in the data, so no backup is required. On the other hand, however, the document management apparatus has a demerit that the area for storing documents in a long-term operation simply increases.

  Further, the document management apparatus stores different versions of one document in a storage area in a distributed manner every time a document is revised. Therefore, even when a document that is no longer needed is deleted, the document management apparatus can only free the storage area in a worm-eaten state, and it is difficult to reorganize the storage area after deleting the document.

Hereinafter, embodiments will be described with reference to the drawings.
[First Embodiment]
First, the document management apparatus according to the first embodiment will be described with reference to FIG. FIG. 1 is a block diagram of a document management apparatus according to the first embodiment.

  The document management apparatus 1 manages an electronic document. The document to be managed is managed by version number. When updating (adding, changing, or deleting) the contents of a document, the document management apparatus 1 saves the updated document (new version document) without deleting the previous document (old version document). . As a result, the document management apparatus 1 stores the update history and update contents of the document to be managed in a checkable manner.

  The document management apparatus 1 includes a document storage unit 2, an acquisition unit 4, a storage unit 5, and a storage area change unit 6. The document storage unit 2 stores a document. The document storage unit 2 is realized by, for example, an HDD (Hard Disk Drive), a nonvolatile semiconductor memory, other storage devices, and the like, and holds a required storage area with one or more configurations. In the document storage unit 2, a plurality of storage areas 3 are set. The storage area 3 has a predetermined unit area and can store a plurality of documents. The predetermined unit is, for example, a unit of time such as year, month, or week, or a unit for setting an area size based on a pre-estimation such as the number of stored items and storage capacity, and can be determined according to the operating environment. The area size of each storage area 3 may be the same or different. For example, the document management apparatus 1 sets each storage area 3 in units of months such as a January storage area, a February storage area, and so on. At this time, the area size allocated every month may be equal to 10 TB (terabytes), or in consideration of seasonal variation, the quiet period may be 5 TB and the busy period may be 30 TB.

  The acquisition unit 4 acquires a new document (new document or revised document). The document to be acquired is an electronic document (electronic document). The document format may be anything as long as it can manage the version number. For example, digitized documents include image data read from a scanner, character data obtained by converting image data into OCR (Optical Character Recognition), document data created by an application such as a word processor, and the like.

The storage unit 5 stores the document (document (new version)) acquired by the acquisition unit 4 in one of a plurality of storage areas 3. The storage unit 5 switches the storage area 3 as a storage target of the document (new version) to a new storage area 3 every time a predetermined condition such as elapse of a predetermined period is satisfied (for example, monthly change).

The storage area changing unit 6 searches for a document (document (old version)) that is an old version of the document (new version) stored by the storage unit 5. When there is an old version of the document (new version), the storage area changing unit 6 stores the document (old version) in the same storage area 3 as the document (new version). The storage area changing unit 6 deletes the document (old version) from the storage area 3 where the document (old version) has been stored. In this way, the storage area changing unit 6 changes the storage area of the document (old version). When the document (new version) has a plurality of revisions, the storage area changing unit 6 changes the storage areas of the plurality of documents (old version).

  Thereby, all versions of the document stored in the document management apparatus 1 are stored in the same storage area 3. Therefore, the document management apparatus 1 does not store different versions of documents in a plurality of storage areas 3 in a distributed manner. Therefore, when the document management apparatus 1 deletes a document in one storage area 3, it is not necessary to check whether a different version of the document exists in another storage area. Further, when deleting one document, a plurality of versions can be deleted at once. As described above, the document management apparatus 1 can easily release the storage area 3, and can easily reorganize the storage area 3 for storing the document.

Next, a more specific document management system will be described as the second embodiment.
[Second Embodiment]
First, a configuration example of the document management system will be described with reference to FIG. FIG. 2 is a diagram illustrating a configuration example of a document management system according to the second embodiment. In the second embodiment, a document management system 10 that manages forms in a financial institution such as a bank will be described as an example of a document management system. The document management system 10 is not limited to the form management in the financial institution exemplified, but in addition to the form management such as bills and invoices in companies, book management, ledger management, etc. It can be applied to document management with changes (addition, correction, and deletion).

  The document management system 10 includes a network 19 that connects the centralized center 11 and the sales office 16. The centralized center 11 includes a document registration server 12, a document management server 13, a storage 14, and a terminal device 15. The store 16 includes a terminal device 17 and a scanner (document reading device) 18.

  In the sales office 16, a form is generated for each transaction. The form is optically read by the scanner 18. The scanner 18 generates image data from the form. The terminal device 17 transmits the image data generated by the scanner 18 to the document registration server 12. The document registration server 12 has various data (form layout data, form description dictionary data, etc.) necessary for form recognition, identifies the form type from the image data, and recognizes the description contents according to the form layout. .

  The operator checks the recognized content of the form, and inputs management information (described later with reference to FIG. 3) based on the recognized content. The document registration server 12 determines whether new registration or update registration of a document to be registered is made based on the recognized contents of the form. A distinction between new registration and update registration of a document registered by the operator can also be specified. The document registration server 12 adds management information to a document for which the distinction between new registration and update registration is specified, and requests the document management server 13 to register.

The document management server 13 saves image data as a document entity and corresponding management information in the storage 14.
The terminal device 15 has a function of searching for image data as a document entity from management information, and enables browsing of forms on a browser basis.

  The document management system 10 has a document registration server 12, a document management server 13, a storage 14, a terminal device 15, a terminal device 17, and a scanner 18 distributed in a centralized center 11 and a plurality of sales offices 16. However, all of these may be centrally arranged in one base.

  Further, although the document management system 10 shares functions with the document registration server 12, the document management server 13, the storage 14, the terminal device 15, and the terminal device 17, functions may be shared with different combinations. One device may have all the functions.

  The document management system 10 realizes generation of image data from a form using the scanner 18 and the terminal device 17 and transmission of the image data to the document registration server 12 by a digital multi-function peripheral having a scanner function and a communication function. You can also.

  Next, document entities and management information stored in the storage 14 by the document management server 13 according to the second embodiment will be described with reference to FIG. FIG. 3 is a diagram illustrating a configuration of document data and document management information according to the second embodiment.

  The storage 14 stores document data (data including document entities) 50 and document management information 60. The document data 50 includes file management information 51. The file management information 51 includes information for specifying and managing a document entity such as an identification ID, a version number, a file number, and a file name, and a magic code used to determine the validity of the file entity and document entity that are document entities. including.

  The identification ID is information that uniquely identifies the document. The version number is the version number of the document. For example, 1 is set for the first version, and a value incremented by 1 is set for each revision. The file number is a number for identifying a file constituting a document. When one document is composed of a plurality of files, for example, a number is sequentially assigned. For example, when one page image is one file, a document composed of a plurality of pages is a plurality of files.

  The file name is a name of a file constituting the document. A file entity is an entity of a file constituting a document, and takes a file format to facilitate computer management. The magic code is data used to determine the validity of a document that temporarily exists twice when moving the storage area of the old version data. The document is validated when the magic code of the file management information 51 matches the magic code of the document information 62 described later, and invalidated when they do not match.

  The document management information 60 includes search key information 61, document information 62, and access right information 63. The search key information 61 includes an identification ID, a version number, and a search key (search key 1, search key 2,...). The identification ID is information that uniquely identifies the document. The version number is the version number of the document. The search key is information used for searching for a document. For example, the search key is information such as a form name, form code, name, address, telephone number, transaction type, amount, etc. described in the form. Information (character string or code) recognized by the document registration server 12, information set by the operator, and the like are registered as the search key.

  The document information 62 includes an identification ID, a version number, a creation date / time, an update date / time, a document name, an ACLID (Access Control List ID), and a magic code. The identification ID is information that uniquely identifies the document. The version number is the version number of the document. The creation date and time is the date and time when the first edition document was created. The update date / time is the creation date / time of the revised document. The document name is the name of the document. ACLID is identification information that uniquely specifies an access right. The magic code is data used to determine the validity of a document that temporarily exists twice when moving the storage area of the old version data.

  The access right information 63 includes ACLID and authority information. ACLID is identification information that uniquely specifies an access right. The authority information is information indicating operation authority such as update, deletion, and browsing.

  The file management information 51, the search key information 61, and the document information 62 are linked with an identification ID and a version number, respectively. Further, the document information 62 and the access right information 63 are linked by ACLID, respectively.

Next, a hardware configuration example of the document management server 13 according to the embodiment will be described with reference to FIG. FIG. 4 is a diagram illustrating a hardware configuration example of the document management server according to the second embodiment.
The document management server 13 is realized by a computer executing a required program. Note that the document registration server 12, the terminal device 15, and the terminal device 17 can also be realized by a hardware configuration similar to that of the document management server 13.

  The entire document management server 13 is controlled by a CPU (Central Processing Unit) 101. A random access memory (RAM) 102, a hard disk drive (HDD) 103, a communication interface 104, a graphic processing device 105, and an input / output interface 106 are connected to the CPU 101 via a bus 107.

  The RAM 102 temporarily stores at least a part of an OS (Operating System) program to be executed by the CPU 101 and an application program for realizing a document management function. The RAM 102 stores various data necessary for processing by the CPU 101. The HDD 103 stores an OS and application programs.

A monitor 108 is connected to the graphic processing device 105. The monitor 108 displays a predetermined GUI (Graphical User Interface) for performing reboot management.
The monitor 108 is a liquid crystal display, for example. The graphic processing device 105 displays an image on the monitor 108 in accordance with a command from the CPU 101.

  A keyboard 110 and a mouse 111 are connected to the input / output interface 106. The input / output interface 106 is connectable to a portable recording medium interface that can write information to the portable recording medium 112 and read information from the portable recording medium 112. The input / output interface 106 transmits signals sent from the keyboard 110, the mouse 111, and the portable recording medium interface to the CPU 101 via the bus 107.

  The communication interface 104 is connected to a network (not shown). The communication interface 104 transmits / receives data to / from another computer via a network (not shown).

With the hardware configuration as described above, the processing functions of the present embodiment can be realized.
The document management server 13 can be configured to include modules each composed of an FPGA (Field Programmable Gate Array), a DSP (Digital Signal Processor), or the like, or can be configured without the CPU 101. In this case, each document management server 13 includes nonvolatile memory (for example, EEPROM (Electrically Erasable and Programmable Read Only Memory), flash memory, flash memory type memory card, etc.) and stores module firmware. The nonvolatile memory can write firmware via the portable recording medium 112 or the communication interface 104. As described above, the document management server 13 can also update the firmware by rewriting the firmware stored in the nonvolatile memory.

Next, the document storage process executed by the document management server 13 will be described in detail with reference to FIG. FIG. 5 is a flowchart of document storage processing according to the second embodiment.
In response to the document registration request, the document management server 13 executes document storage processing.

[Step S11] The document management server 13 searches for a document (old version) that is an old version of the document (document (new version)) that has received the registration request.
[Step S12] As a result of searching for a document (old version), the document management server 13 proceeds to step S13 if there is a document (old version), and proceeds to step S16 if there is no document (old version).

  [Step S13] The document management server 13 determines whether the document (old version) is a document of the current month. In other words, the document management server 13 determines whether or not the storage area for storing the document (new version) is the same as the storage area for storing the document (old version). The document management server 13 proceeds to step S16 if the document (old version) is a document of the current month, and proceeds to step S14 if it is not the document of the current month.

  [Step S14] The document management server 13 sets a moving flag indicating that the document (old version) is moving. When there is a reference request to the document entity while the moving flag is set, the document management server 13 responds to the reference request with the document (old version) before moving the storage area.

[Step S15] The document management server 13 acquires a document (old version) from a storage area for storing the document (old version).
[Step S16] The document management server 13 stores all versions of the document to be stored in the storage area of the current month. That is, the document management server 13 saves the document (new edition) in the save area of the current month. Then, if there is an old version of the document (new version), the document management server 13 stores all the documents (old version) in the current month storage area.

  [Step S17] The document management server 13 registers management information of the document to be saved. Here, the document management server 13 sets the same value for the magic code of the document information 62 and the magic code of the file management information 51 of the document to be stored. The magic code set here is different from the magic code of the file management information 51 of the document (old version) in the storage area for storing the document (old version). As a result, a document (old version) that does not match the magic code of the document information 62 is invalid.

  [Step S18] The document management server 13 determines whether the moving flag is set. The document management server 13 proceeds to step S19 if the moving flag is set, and ends the document saving process if the moving flag is not set.

[Step S19] The document management server 13 deletes the document (old version) from the original save area of the document (old version) saved in the save area of the current month.
[Step S20] The document management server 13 cancels the setting of the moving flag and ends the document storage process.

  As a result, all versions of the document stored in the document management system 10 are stored in the same storage area. Accordingly, the document management system 10 does not store different versions of documents in a plurality of storage areas.

  The document management server 13 deletes the document (old version) from the original storage area of the document (old version) stored in the storage area of the current month, but does not delete the document (old version) during the document storage process. It may be performed in the process of deleting a document separately.

  Although the procedure for the document management server 13 to sequentially execute the document saving process has been described, a time-consuming process such as data movement may be executed in the background.

  Next, a specific example of document storage processing executed by the document management server 13 will be described in detail with reference to FIGS. 6 and 7 are diagrams illustrating an example of document storage in the document management system according to the second embodiment.

  First, the document management information 200, the storage area 201, and the storage area 202 shown in FIG. 6 will be described. The storage area 201 and the storage area 202 are storage areas secured in the storage 14. For the sake of brevity, a storage area 201 and a storage area 202 are shown. In the storage 14, a plurality of storage areas (not shown) are assigned and set for each month.

  A storage area 201 is a storage area for storing a document for March 2009. The storage area 201 stores document A (first version), document A (second version), and document B (first version) as documents for March 2009. A storage area 202 is a storage area for storing a document for April 2009. The storage area 202 stores document C (first version), document C (second version), and document C (third version) as documents for April 2009.

  The document management information 200 indicates a document name and a registration date / update date (whichever is the latest date) in order to simplify the explanation. These pieces of information correspond to the creation date / time, update date / time, and document name of the document information 62. The registration date / update date of document A 2009/3/11 indicates that document A is stored in the storage area 201 in which documents for March 2009 are stored. The registration date / update date of the document B, 2009/3/25, indicates that the document B is stored in the storage area 201 in which documents for March 2009 are stored. The registration date / update date of document C, 2009/4/06, indicates that document C is stored in the storage area 202 for storing documents for April 2009.

  FIG. 7 shows a case where the document A (third version) is registered from the state shown in FIG. The document management server 13 searches for a document (document A (first version), document A (second version)) that is an old version of document A (third version). The document management server 13 confirms that the document A (first version) and the document A (second version) are stored in the storage area 201. Further, the document management server 13 stores the document A (first version) and the document A (second version) in a document in April 2009, which is the update month of the document A (third version), that is, the storage area 202. Make sure it is not. The document management server 13 sets a moving flag indicating that the document A (first version) and the document A (second version) are moving. Thus, when there is a reference request for the document A (first version) and the document A (second version), the document management system 10 stores the document A (first version) and the document A stored in the storage area 201. Reply (second edition).

  The document management server 13 acquires the document A (first version) and the document A (second version) from the storage area 201 and stores them in the storage area 202. The document management server 13 registers (updates) the management information of the document A (third version) that is the revised document, the document A (first version) that is the document before the revision, and the document A (second version). The document management server 13 rewrites the magic code and invalidates the document A (first version) and the document A (second version) in the storage area 201. The document management server 13 deletes the document A (first version) and the document A (second version) from the storage area 201 and cancels the setting of the moving flag.

  Thereby, the storage area 201 stores the document B (first version), and the storage area 202 stores the document C (first version), the document C (second version), the document C (third version), and the document A. (First edition), document A (second edition), document A (third edition) will be saved. As described above, all versions of the document stored in the document management system 10 are stored in the same storage area.

  Next, document deletion processing executed by the document management server 13 will be described in detail with reference to FIG. FIG. 8 is a flowchart of document deletion processing according to the second embodiment. In response to the document deletion request, the document management server 13 executes document deletion processing. An operator can make a document deletion request from the terminal device 15 or the terminal device 17. The document deletion request includes a deletion request specifying a document and a deletion request specifying a condition such as a period.

  [Step S31] The document management server 13 determines whether or not the deletion request is specified for a period. The document management server 13 proceeds to step S33 when the deletion request is specified for a period, and proceeds to step S32 when the deletion request is not specified for a period.

  [Step S32] The document management server 13 determines whether or not the deletion request is a document designated. The document management server 13 proceeds to step S33 when the deletion request is a document designated, and ends the document deletion process when the document is not designated.

[Step S33] The document management server 13 identifies a storage area that matches the specified conditions for the deletion request.
[Step S34] The document management server 13 deletes the management information of the document to be deleted.

[Step S35] The document management server 13 deletes the document to be deleted.
[Step S36] The document management server 13 determines whether another document is stored in the storage area from which the document is deleted. The document management server 13 proceeds to step S37 when no other document is stored in the storage area from which the document has been deleted, and ends the document deletion process when another document is stored.

[Step S37] The document management server 13 releases the storage area from which the document has been deleted, and ends the document deletion process.
Next, a specific example of the document deletion process executed by the document management server 13 will be described in detail with reference to FIGS. 9 and 10 are diagrams illustrating an example of document deletion in the document management system according to the second embodiment.

  First, FIG. 9 shows a case where deletion is performed by designating a document like document B from the state shown in FIG. The document management server 13 specifies the storage area 201 of the document B requested to be deleted. The document management server 13 deletes the management information of the document B requested to be deleted. The document management server 13 deletes the document B (document B (first version)) requested to be deleted from the storage area 201. The document management server 13 confirms that no other document is stored in the storage area 201 and releases the storage area 201.

  Similarly, FIG. 10 shows a case where deletion is performed by designating a period as in March 2009 from the state shown in FIG. The document management server 13 specifies the storage area 201 for the period requested for deletion. The document management server 13 deletes the management information of document A (document A (first version), document A (second version)) and document B (document B (first version)) stored in the storage area 201. To do. The document management server 13 stores the document A (document A (first version), document A (second version)) and document B (document B (first version)) stored in the storage area 201 from the storage area 201. delete. The document management server 13 confirms that no other document is stored in the storage area 201 and releases the storage area 201.

  As described above, the document management server 13 deletes the document A (first version), the document A (second version), and the document B (first version) from the storage area 201 without confirming other storage areas. be able to. This is because, when it is desired to delete a document before March 2009, documents after April 2009 are not stored in the storage area before March 2009, including the document before the revision. Therefore, the document management system 10 can collectively delete documents in units of storage areas, can easily release storage areas, and can easily reorganize storage areas.

  In this way, the document management system 10 can efficiently use limited storage resources in an environment in which old documents that have passed a certain retention period are sequentially deleted, and the storage capacity of the storage 14 needs to be increased to the minimum. Long-term operation can be continued as long as possible.

  Next, document update in the case where one document is composed of a plurality of files will be described with reference to FIGS. 11 to 13 using the third embodiment. 11 to 13 are diagrams illustrating an example of document update in the document management system according to the third embodiment.

[Third Embodiment]
In the third embodiment, document updating in the case where one document is composed of a plurality of files will be described. Note that the same configuration as that of the third embodiment will be described using the same reference numerals.

  First, the document management information 210, the storage area 201, and the storage area 202 shown in FIG. 11 will be described. The storage area 201 and the storage area 202 are storage areas secured in the storage 14. For the sake of brevity, a storage area 201 and a storage area 202 are shown. In the storage 14, a plurality of storage areas (not shown) are assigned and set for each month.

  A storage area 201 is a storage area for storing a document for March 2009. The storage area 201 stores a file A1, a file A2, and a file B1 as files constituting a document for March 2009. A storage area 202 is a storage area for storing a document for April 2009. The storage area 202 stores a file C1, a file C2, and a file C3 as files constituting a document for April 2009.

  The document management information 210 indicates a document name, version number, and registration date / update date (whichever is the latest date) for the sake of brevity. These pieces of information correspond to the version number, creation date / time, update date / time, and document name of the document information 62. The registration date / update date of document A 2009/3/11 indicates that document A is stored in the storage area 201 in which documents for March 2009 are stored. The registration date / update date of the document B, 2009/3/25, indicates that the document B is stored in the storage area 201 in which documents for March 2009 are stored. The registration date / update date of document C, 2009/4/06, indicates that document C is stored in the storage area 202 for storing documents for April 2009. The files making up each document can be grasped by the file number and file name of the file management information 51.

  From the state shown in FIG. 11, how an update file is added when document A is updated and registered is shown below. The document management server 13 accepts a document registration instruction for updating the document A (first version), which is a pre-revision document, to a revised document (document (second version)) composed of the file A1, the file A2, and the file A3. Execute the document saving process.

  The document management server 13 searches for the files (file A1, file A2) constituting the document A (first version) that is the document before revision. The document management server 13 confirms that the file A1 and the file A2 are stored in the storage area 201. In addition, the document management server 13 confirms that the files A1 and A2 are not stored in the document of the April 2009 update month, that is, the storage area 202. The document management server 13 sets a moving flag indicating that the files A1 and A2 are moving. As a result, the document management system 10 responds to the file A1 and the file A2 stored in the storage area 201 when there is a reference request for the file A1 and the file A2.

  The document management server 13 acquires the file A 1 and the file A 2 from the storage area 201 and stores them in the storage area 202. In addition, the document management server 13 stores the file A3 in the storage area 202 (FIG. 12).

  The document management server 13 registers (updates) the management information of the document A (first version). As a result, the document A (first version) is changed from the file A1 and the file A2 stored in the storage area 201 to the file A1 and the file A2 stored in the storage area 202. Further, the document management server 13 registers management information of the document A (second version). As a result, the document A (second version) becomes the file A1, the file A2, and the file A3 stored in the storage area 202. In this way, the document management system 10 links one file to a plurality of versions, so that it is not necessary to hold duplicate data in the plurality of versions.

  The document management server 13 rewrites the magic code and invalidates the files A1 and A2 stored in the storage area 201. The document management server 13 deletes the files A1 and A2 stored from the storage area 201 and cancels the setting of the moving flag.

  As a result, the storage area 201 stores the file B1, and the storage area 202 stores the file C1, the file C2, the file C3, the file A1, the file A2, and the file A3. As described above, all versions of the document stored in the document management system 10 are stored in the same storage area.

  In addition, once the file stored in the document management system 10 is stored in the storage area, the data is not rewritten unless it is deleted. Therefore, the storage area for storing data before the storage area for the current month does not need to be regularly backed up once the backup is taken. Therefore, the document management system 10 can reduce the time required for backup maintenance even when large-scale data is held.

  The above processing functions can be realized by a computer. In that case, a program describing the processing contents of the functions that the document management apparatus 1 and the document management system 10 should have is provided. By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing contents can be recorded on a computer-readable recording medium (including a portable recording medium). Examples of the computer-readable recording medium include a magnetic recording device, an optical disk, a magneto-optical recording medium, and a semiconductor memory. Examples of the magnetic recording device include a hard disk device (HDD), a flexible disk (FD), and a magnetic tape. Optical discs include DVD (Digital Versatile Disc), DVD-RAM, CD-ROM, CD-R (Recordable) / RW (ReWritable), and the like. Magneto-optical recording media include MO (Magneto-Optical disk).

  When distributing the program, for example, portable recording media such as a DVD and a CD-ROM in which the program is recorded are sold. It is also possible to store the program in a storage device of a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program. Further, each time the program is transferred from the server computer, the computer can sequentially execute processing according to the received program.

Note that various modifications can be made to the above-described embodiment without departing from the gist of the embodiment.
Further, the above-described embodiments can be modified and changed by those skilled in the art, and are not limited to the exact configurations and application examples described.
