Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an integrated document management apparatus for integrating and managing a plurality of document management systems for processing a managed document.

[0002]

2. Description of the Related Art In recent years, a large number of electronic documents (hereinafter, referred to as "documents") created using a computer or the like have come to exist in various places such as offices. Various document management systems are used to manage documents and share them with a plurality of users. Generally, such a document management system is desired to be used by a plurality of users at the same time, and is realized in a distributed environment such as a client / server configuration.

The document management system has various processing functions for the managed document, and an application cooperating with the document management system performs various processing on the document by using the processing functions. Has been realized. For example, when a document editor implements the document version control function, it does not implement the document version control function on its own, but uses the document version control function provided in the document management system. Other document editors also implement the version management function by utilizing the document version management function provided in the document management system. As described above, since the application uses the processing function provided in the document management system, even if the application is different, the version management for the document managed by the document management system can be realized without any trouble.

Some of the above-described document management systems have different functions and performances, such as one having an excellent search function and one having an excellent document version management and sharing function. For this reason, when managing a document in an office or the like, a plurality of document management systems are properly used.

[0005] When a plurality of document management systems are properly used, a function managed by a certain document management system is generally used for a document managed by a certain document management system. As shown in FIG. 20, the user cannot use
For example, a document is moved to an appropriate document management system.

Hereinafter, several methods for linking a plurality of data and a plurality of document management systems will be described.

As a method of linking a plurality of data management systems having different functions (hereinafter referred to as method 1), data registered in one data management system is converted and registered in another data management system again. Has been done. For example, in the invention described in JP-A-7-230474, a simple and high-speed ISAMDB (Indexed Sequential
Access Method DataBase), input manufacturing data and use the ISAMDB for simple search.
All data is converted from the DB and registered in the relational database, and the relational database is used for processing for performing complicated access such as quality control. Except for converting and registering data, the databases are managed independently of each other.

Further, a method described in US Pat. No. 5,608,904 (hereinafter referred to as method 2) realizes a search by associating data of a text search system with data of a relational database system. The two databases are linked by providing an equivalent access method to the bibliographic information of the existing document and the bibliographic information of the document in the text search system.

As a method for appropriately utilizing data management systems having different performances (hereinafter referred to as method 3),
There is a method described in JP-A-7-319902. In this method, access performance is improved by preparing a plurality of storage devices having different performances and moving data between the storage devices using locality of access such as access frequency.

[0010] Further, the following literature relating to a multi-database integrating and using a plurality of relational database systems having different schemas, and an Intelligent Input by ARPA.
integration of Information reference architecture (Refer
ence Architecture for the Intelligent Integration o
f Information version 2.0, 1995) proposes a method (hereinafter referred to as method 4) for integrating data in stages, such as protocols, data types, and schemas, using wrappers and mediators. For example, USP 5596
No. 748, US Pat. No. 5,556,332, Japanese Patent Application Laid-Open No. 7-44443, etc. realize a method of connecting different database systems. As a connection method, there are a method of connecting by converting a search expression or an operation command, and a method of connecting by converting the data model itself.

As a method of combining a plurality of document management systems (hereinafter referred to as method 5), ODMA (ft
p: //ftp.capcon.net/pub/aiim/services/api) or DMA
(http://www.aiim.org/dma/), a method of preparing a common interface and integrating a document management system has been proposed.

A method of coordinating a plurality of functions to be shared (hereinafter referred to as method 6) is realized in a distributed processing system of a function distribution type. For example, a document on a file server is converted to a print server. This is equivalent to printing with.

[0014]

The above-mentioned methods have various problems as described below. In the method 1, the user must use a plurality of prepared data management systems. Therefore, the user must learn how to use a plurality of data management systems, and must appropriately determine which data management system to use according to the usage status. Further, since each data management system is independent, it is difficult for a user to cooperate and process the same data stored in each data management system, and it is difficult to manage data. For example, in the method described in JP-A-7-230474, a single management system having original data is defined in order to simplify the management of copies, and a specific management system is used for data input work. The use of is forced. Therefore, there is a limitation on the method of use except for a specific user who performs a fixed work, and the usability is poor.

In method 3, a plurality of systems having different performances are used as systems having the same function.
The user can obtain an effect only on the function of the common part of each system. In other words, the functions are more limited than when using one specific system. Therefore, in order to improve usability, a system designer must select a system having many common functional parts.

In methods 2 and 4, the schema is converted and the document database is treated like a relational database. That is, the document is converted so that the document can be handled in the same manner as the tapple. For example, attributes assigned to documents,
It is converted into a taple using a part of the document contents representing bibliographic information and the like. With this method, document-specific information such as document content, document logical structure, and document version cannot be effectively used.

In comparison, in the DMA of method 5,
Because it is important to manage documents in advance,
Various information unique to the document can be used. However, an interface with an application and an interface with a document management system are specified, and this method cannot be applied to a document management system that does not satisfy these rules and an application that uses the document management system. For example, already,
This method cannot be applied to the operating document management system unless the management system is changed to satisfy the regulations.

In the method 6, in general, a unique method is used for realizing a function and a coordination method, and cannot cooperate with another system. If an API (Application Pro
Even if a cooperation / connection method such as a gramming interface is provided / disclosed, a problem similar to the method 5 described above occurs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and makes it possible to easily and efficiently use the functions of a plurality of document management systems without making the user aware of the plurality of document management systems.

The registration / change date and time 28 and the original flag 29 are set by the overall control means 1 according to the situation, and other items may be set according to an explicit command from the user. Alternatively, it is also possible for the overall control means 1 to set according to the situation. In this embodiment, "TRUE" is used as the original flag to indicate that the original is an original flag, and "FALSE" is used to indicate a non-original replica.

The folder information management means 4 has a function of managing information on folders for classifying, organizing, and managing a plurality of documents. In the present embodiment, the folder information management means 4 manages information by using a folder management table shown in FIG. doing. Note that the folders are preferably created for each user or for each type of document.

The folder management table includes a folder ID 31 for uniquely specifying a folder, a folder name 32, a folder owner 33, an access right 34 to the folder, and a default access right to a document registered in the folder. 35, a document management system that stores the entity of the folder, an entity folder 36 that specifies an address in the document management system, and a document ID 37 of the document registered in the folder. By designating the entity folder 36, it is possible to designate a location for storing a document registered in the folder.

The document management system information management means 5 has a function of managing information relating to each document management system. In this embodiment, the information is managed by a system management table shown in FIG. The system management table includes a document management system name (system ID) 41, a storable document type 42, and a function 4 to be provided for the stored document.
3 and the default storage location 44 when storing documents
And a capacity 45 capable of storing a document, and a free space 46. For example, for the document management system A1, the system ID is "A1", the storable document type is an SGML document, and the provided functions are the normal search, structure search, and editing functions, and the document is stored. The default storage location is "/ common", the capacity is 5 GB, and the information that the free capacity is 1 GB is managed.

The user information management means 6 has a function of managing a user name and a password of each user. In the present embodiment, the user information is managed by a user information management table shown in FIG. This user information management table has a user name and password 51 for each integrated document management device for each user, and an actual user name and password 52 for each document management system for each user. Note that the user name super is an administrator account of the integrated document management device, and has an access right to all processes for all documents. That is,
Super is associated with an entity user name, which is an administrator account of each document management system, and these entity user names have access rights to all processes in all documents in each document management system. It has become. It is desirable that the user management information means 6 be strictly stored by being encrypted.

The search formula conversion means 7 converts the search formula received from the overall control means 1 into each of the document management systems A1, A2,
It converts into a search formula suitable for B, C, D, and the whole control means 1
Notify.

The editor selecting means 8 includes the input / output control means 1
1 starts an appropriate editor according to the type of the document received. The operation input unit 9 stores a document from the user,
An operation command including information for specifying a processing content such as retrieval, editing, deletion, search, and the like and a document to be processed is received and notified to the input / output control unit 11.

The display means 10 displays information notified from the input / output control means 11, such as a search result. The means 8 to 10 are provided in a computer used by each user. The input / output control unit 11 notifies the general control unit 1 of the user's operation command received by the operation input unit 9, and receives the operation result notified from the general control unit 1, document data, and the like, and displays it. Means 10 are displayed.

Here, the processing system specifying means, control means, document management control means, registration means, acquisition means, management detection means, second registration means, second acquisition means, detection means, 3 registration means and second document management means,
It is mainly constituted by the function of the overall control means 1 described above.

Next, the operation of the above-described integrated document management device will be described with reference to the drawings. The operation of registering and storing a document specified by the user in the integrated document management device will be described with reference to FIG. First, the operation input unit 9 receives a command from a user to store a document, a specification of a document to be stored, a document name, a document type, and in some cases, a specification of a folder in which the document is registered. Next, the input / output control unit 11 notifies the general control unit 1 of the specification of the received document, the document name, the document type, and the folder (step S1). If the document name and the document type can be determined from the document specified by the user, the operation input unit 9 does not need to explicitly receive the document name and the document type from the user. The overall control means 1 determines the document name and the document type from the specification of the document accepted by the user.

Then, the overall control means 1 having received the notification determines whether or not a folder is specified in the notification (step S2). As a result, when a folder is designated, the overall control means 1 acquires an access right to the document registered in the designated folder from the folder information management means 4, associates the document with the designated document, and further associates the folder with the designated document. It is detected whether there is an entity folder in the folder specified by the management means 4 (step S3). If there is an entity folder, the entity folder is designated as the entity folder in the document management system designated as the entity folder. The document is stored in the storage location (step S4).

On the other hand, when the folder is not specified, the overall control means 1 requests the input / output control means 11 to input an access right to the document. The input of the access right to the document is received from the user (step S5). And
When the operation input unit 9 receives the input of the access right from the user and the overall control unit 1 receives the notification of the access right from the input / output control unit 11, or the folder is specified, but the actual folder is specified. If not, the overall control unit 1 refers to the document management system information management unit 5 to check whether or not the received document type can be stored in the document management system D (step S6).

As a result, if the document cannot be stored, the overall control means 1 refers to the document management system management means 5 to store the document in a document management system capable of storing the document (step S7). The document is converted into a document type that can be stored in the document management system D and stored in the document management system D (step S8). According to steps S7 and S8 described above, for example, when the type of the document is "image document", the entity of the image document is stored in the document management system C as the original, and then the character extracting unit 2 extracts the character information from the image document. (Text) is retrieved, and the character information is used as a replica in the document management system D.
Is stored in

When storing a document in the document management system as described above, the overall control means 1 determines whether the user who has designated the document has the right to store the document in the storage destination document management system. Then, whether or not there is free space in the storage destination is monitored (step S10). Then, when the user does not have the right to store the data in the storage destination or when there is no free space in the storage destination, an error message is displayed (step S11), and the process ends. On the other hand, when the above case does not occur, that is, when the document can be normally stored in the document management system, the overall control unit 1 generates a document ID for the stored document, and outputs the entity ID of the document and the document ID of the document. It is registered in the document information management means 3 together with information such as the access right, the date and time when the document was registered, and the original flag (step S12).

Here, the document shown in FIG. 2 stored by the above processing will be described.
The first version of the document 1 "is the folder name" / inf shown in FIG.
o ”is a specified and stored document having a document ID“ 0 ”.
The first version of the document “002” is the folder name “/ r” shown in FIG.
eport ”is specified and stored in the document I.
The first version of the document D “0003” is a document stored without specifying a folder. Since this document is an image document, the original is stored in the document management system C, and the document is stored in the document management system D in text format. Is stored.

As described above, a user can store a document without being aware of a document management system capable of storing a document to be stored. In this embodiment, information required for full-text search, such as the entity of the document or text included in the document, has a full-text search function, except for the document registered in the specified folder. Since the document is stored in the document management system D having a high search processing speed, the full-text search can be performed on the document, and the full-text search can be efficiently performed. For the documents registered in the folder whose entity folder is designated, if the entity or the text of the document is stored in the document management system D, all the documents managed by the integrated document management apparatus can be used. In addition, a full-text search can be performed, and a full-text search can be efficiently performed.

If the document specified to be stored is given the editing right, the document type of the specified document is stored in a document management system that can store and edit the document in addition to the document management system D. Then, the editing process for the document can be performed quickly.

Next, an operation when an edit command is received from a user for a document managed by the integrated document management apparatus will be described with reference to FIG. First, the operation input unit 9 receives a command including a command to edit a document from a user and a command including a document ID of a document to be edited, and locks and retrieves the document received by the overall control unit 1 as described later. Perform (Step S21). Next, the editor selecting unit 8 activates the document editor according to the document type of the retrieved document, the operation input unit 9 receives an editing operation on the document from the user (step S22), and the document edited by the user's editing operation. Is stored as a temporary file by the overall control means 1 (step S23), and the above processing (steps S22 and S2) is performed until the operation input means 11 receives a command from the user to end the editing.
Step 3) is repeated (step S24).

When the operation input means 9 receives a command to end editing from the user, the operation input means 9 further receives a command as to whether or not to cancel editing from the user (step S25). Is received, the overall control unit 1 performs a process of canceling registration of an edited document described later (step S2).
6) On the other hand, when an instruction not to cancel is received, the overall control means 1 performs processing for registering and storing an edited document, which will be described later (step S27).

Next, a detailed procedure relating to the above-described document retrieval processing (step S21) will be described with reference to FIG. 8. First, the operation input means 9 receives an edit command including the document ID of the document to be edited from the user ( Step S31),
The overall control unit 1 detects whether or not the user has the editing right for the document with the document ID based on the information of the document information management unit 3 (step S22). It is detected whether or not it is in the state (step S33).

When the user does not have the editing right or when the document is locked, the user cannot edit the document of the document ID, so that an error message is displayed and the processing is performed. Is ended (step S34). On the other hand, in cases other than the above, the overall control unit 1 refers to the entity ID corresponding to the document ID from the document information management unit 3, and the document management system represented by the entity ID edits the document with the document ID. It is determined by referring to the document management system information management means 5 whether or not the function can be provided, that is, whether or not the document type of the document having the document ID can be stored and has the editing function (step S3).
5).

As a result, if the editing function cannot be provided, the overall control means 1 controls the document management system information management means 5
, A document management system that can provide an editing function is specified, the document with the document ID is copied to the document management system (step S36), and the corresponding document is locked and extracted from the document management system that copied the document. (Step S37) On the other hand, if the editing function can be provided, the corresponding document is locked and extracted from the stored document management system (Step S37).

Then, the overall control means 1 updates the document information management means 3 based on the change in the state of the document (step S).
38). That is, when the document is copied, the entity ID of the copy destination document, the date and time when the copy was performed, “FALSE” indicating that the copied document is not the original, and the like are set.

As described above, when a document to be edited by the user is stored in a document management system having no editing function, the document is moved to a document management system having an editing function. An editing function can be provided.

Next, a detailed procedure relating to the above-described edit canceling process (step S26) will be described with reference to FIG. 9. First, the operation input means 9 receives a command from the user to cancel editing (step S41). The overall control unit 1 confirms that the entity of the document to be canceled is locked in the editable document management system and that the user who locked the document is the one who issued the cancellation command (step S42, S43).

As a result, if the confirmation is not successful, the overall control means 1 causes the display means 10 to display an error,
The process ends (step S44). On the other hand, if it can be confirmed, the overall control means 1 releases the lock on the entity of the document to be canceled by the document management system (step S45), and discards the edited document stored as the temporary file (step S45). S46).

Next, a detailed procedure relating to the above-described edited document registration / storage processing (step S27) will be described with reference to FIG. 10. First, the operation input means 9 receives a command from the user to register an edited document. (Step S51) The general control means 1 confirms that the entity of the document to be registered is locked in the editable document management system, and that the user who locked the document is the user who issued the registration. (Steps S52 and S53).

As a result, if no confirmation is made, the overall control means 1 causes the display means 10 to display an error,
The process ends (step S54). On the other hand, if it can be confirmed, the overall control means 1 causes the document management system to rewrite the edited document stored as the temporary file to the document entity, and further releases the lock on the document entity (step S55).

Next, a process of advancing the version of the document edited by the overall control means 1 is performed on the document information management means 3 (step S56). That is, a new version is added to the document ID in the document information management means 3 and the other items are set. If the replica of the version before the added version is stored in the editable document management system, the overall control unit 1 causes the corresponding document management system to delete the replica and the document information management unit 3. The information such as the entity ID of the middle replica is deleted (step S57).

Here, the document shown in FIG. 2 edited by the above processing will be described.
The second version of the document "1" is created by the user sayuda, who has the right to change the access right, to obtain the editing right and edit the first version of the document. An edited document exists.

Next, the operation when a search command is received from the user will be described with reference to FIG. First, the operation input means 9 receives a command from the user to search and an input of a search formula for searching for a desired document (step S61). In this embodiment, a structure search for a structured document is also possible. As a structure search formula for performing the structure search, for example, a document having a logical structure such as a chapter, a section, or a paragraph as shown in FIG. When searching,
When searching for a “section” in which the “title” of the “section” includes the keyword “patent” and the “paragraph” of the “section” includes the keyword “search”, the structure search shown in FIG. Equations can be used.

Then, the overall control means 1 is operated by the operation input means 9
Then, it is detected whether or not the search formula accepted is a structure search formula (step S62). As a result, if the search formula is not a structure search formula, the overall control means 1 extracts all the document management systems having a full-text search function from the document management system information management means 5, and further searches the search formula. The search expression conversion means 7 converts the search expression into a search expression suitable for each document management system, and passes the converted search expression to each document management system for search (step S63). And adds the entity ID combined with the system ID of each document management system to the candidate list (step S64).

On the other hand, if the search formula is a structure search formula, it means that the search target is all structured documents managed by all document management systems.
First, the overall control means 1 is a document management system information management means 5
, All the document management systems having the structure search function are extracted from the list, and the structure search formula is further converted into a structure search formula suitable for each document management system by the search formula conversion means 7. Is passed to each of the document management systems to be searched (step S65).

Further, the entire control means 1 removes structural elements from the structure search formula (see FIG. 1).
In the case of the structure search formula shown in FIG. 3, it is converted into "" patent "AND" search "" (step S66), and all document management systems having a full-text search function are extracted from the document management system information management means 5. Then, the full-text search formula is converted into a full-text search formula suitable for each document management system by the search formula conversion means 7, and the converted full-text search formula is passed to each document management system to search for structured documents. (Step S67).

Then, the overall control means 1 receives the management address ID of each document management system of the document obtained by the search in steps S65 and S67, and combines the management address ID with the system ID of each document management system. Add ID to candidate list (step S6)
4). Step S65 and steps S66 and S
67 and 67 may be executed simultaneously, and by doing so, the search time can be reduced.

Next, the overall control means 1 extracts one entity ID from the candidate list (step S68), and detects whether or not the document of the entity ID is managed by the document information management means 3 (step S69). If the document is not managed, it means that the document is stored uniquely in the document management system. Therefore, by assigning a new document ID to the document and registering it in the document information management means 3, the integration is performed. The document can be used in the document management device (step S70). If information to be managed by the document information management means 3 is obtained from the document, the general control means 1 also registers the information.

On the other hand, if the document is a managed document, the overall control unit 1 performs a registration date / time confirmation process described later to make the document information management unit 3 available so that the latest document can be used.
Is updated (step S71).

Next, if the search formula is not a structure search formula, the overall control unit 1 detects whether or not the document of the entity ID is stored in the search result list. In addition to the above, the search result list is displayed on the display means 10, and if the search result list is already present, nothing is performed. (Steps S73 to S7
5).

On the other hand, if the search formula is a structure search formula, the overall control means 1 further checks whether the document management system storing the document of the entity ID has a structure search function. The judgment is made by the management system information management means 5 (step S76). As a result, when the document has the structure search function, it indicates that the document of the entity ID is a document searched by the structure search, and the overall control unit 1 immediately displays the search result list. On the other hand, if there is no structure search function (steps S73 to S75), the overall control means 1 copies the document with the document ID to a document management system capable of structure search,
The document management system is caused to perform a structure search, and it is determined from the result of the search whether or not the structure corresponds to a structure search formula. If so, a process of displaying a search result list is performed (steps S73 to S75). . Then, the above-described processing steps S68 to S78 are performed for all the candidate lists (step S79).

As described above, a document registered independently of the document management system can be used in the integrated document management device. Further, a structure search can be performed on a document stored in a document management system having no structure search function.

Next, a detailed procedure for the above-described registration date confirmation process (step S71) will be described with reference to FIG. 14. First, the overall control unit 1 extracts the document ID of the corresponding document from the document information management unit 3. (Step S81), referring to the document information management means 3, it is detected whether or not the document ID exists other than in the document management system D (Step S8).
2) If it exists only in the document management system D,
Since this indicates that the document has not been updated, the processing is terminated. On the other hand, if the document exists in another document management system, the document may be updated. Therefore, the general control means 1 accesses the document in the document management system and registers the associated registration / change date and time. Is checked (step S83).

If there is no document entity as a result of this access, the overall control means 1 further detects whether or not the document entity is managed as the original in the document information management means 3 (step S84). , 85).
If the document is managed as an original as a result of this detection, the document is registered independently of each document management system, and is subsequently managed by the integrated document management device. Since it means that the original document itself has been deleted later, the overall control means 1 causes the document management system D to delete the replica document which does not need to be managed (step S86). On the other hand, if the document ID is deleted (step S87), the document is a replica.
Since the original of the document is stored in the document management system D, the entity ID of the document corresponding to the replica is deleted from the document information management means 3 (step S87).

On the other hand, when the document entity exists as a result of the access, the registration / change date and time associated with the entity are registered and associated with the document ID managed by the document information management means. It is detected whether it is newer than the change date and time (step S88). If the registration / change date is new in association with the entity, it means that the document is a newly edited document or the like, and the overall control unit 1 sends the document to the document management system D. The document I is copied by the document information management means 3 (step S89).
The document is registered by updating the version in the entry of D (step S90). Further, when a replica of the document of the previous version exists in the document management system in which the entity of the document is stored, the replica is updated. Then, the document ID and the like of the replica document are deleted from the document information management means 3 (step S91). If the registration / change date and time is old in association with the entity, the process is terminated because the document is not a newly edited document.

According to the above-described operation, the integrated document management device can manage a new document edited and the like. In the above description, whether the document is new or not is determined using the registration / change date and time.
For example, if each document management system manages a document by associating information such as a version with which new or old can be determined, it is also possible to determine whether the document is new based on the associated information. it can.

Next, an operation when a command to take out a document managed by the integrated document management apparatus from the user will be described with reference to FIG. First, the operation input unit 9 receives a command including a command to retrieve from a user and a command including a document ID of a document to be retrieved (step S101), and the overall control unit 1 refers to the user information management unit 6 to issue the command. It is confirmed whether or not the issuing user has the right to read (step S102). If the user does not have the right, the process is terminated. Is detected (step S103).

If no version is specified, the same process as the registration date confirmation process shown in FIG. 14 described above is performed on the received document ID (step S104), and the overall control unit 1 executes the document information management. The entity ID of the original document of the latest version of the document ID is extracted from the means 3, and the corresponding document is extracted by the document management system (step S105).

On the other hand, if a version is specified, the overall control means 1 extracts the entity ID of the original document of the version specified by the document ID from the document information management means 3 and replaces the corresponding original document with the document. It is taken out by the management system (step S105). When extracting the entity ID of the original document, the original flag is set to "TR".
What is necessary is just to extract the entity ID of “UE”. As described above, the user can extract a desired document without grasping the document management system in which the original of the document is stored.

Next, an operation when a deletion command is received from a user for a document managed by the integrated document management apparatus will be described with reference to FIG. First, the operation input means 9
Receives from the user a command to delete the document and a command including the document ID of the document to be deleted and the like (step S11).
1) The overall control means 1 refers to the character information management means 3 to confirm the entity IDs of all the documents associated with the received document ID (steps S112 and S113).
It is detected whether or not the user who issued the command has the right to delete the document (step S114).

As a result, if the user does not have the right to delete, the overall control means 1 displays an error on the display means and terminates the process (step S115). Then, the document of all the entity IDs is deleted from the document management system (step S116), and the entry of the document ID is deleted from the document information management means 3 (step S117). As described above, it is possible to appropriately delete a document without having to know the document management system that manages the document.

Next, an operation when a delete instruction for an old version of a document is received from a user for a document managed by the integrated document management apparatus will be described with reference to FIG.
First, the operation input unit 9 receives from the user a command to delete an old version and a command including the document ID of the document to be deleted (step S121), and the overall control unit 1 causes the character information management unit 3 to delete the old version. (Step S122), it is determined whether or not the user has the right to delete the version (step S12).
3). If the user has the right to delete, the general control unit 1 causes the document management system to delete the corresponding version of the document (step S124), and further deletes the document associated with the document ID received from the character information management unit 3. With reference to the information of the previous version (step S125), the above processing is repeated, and this is performed for all old versions (step S125).
126).

As described above, an old version of a document that does not need to be retained can be appropriately deleted without knowing the document management system that stores the document.

Next, an operation in which the integrated document management apparatus itself deletes unnecessary replica documents from among the documents managed by the integrated document management apparatus will be described with reference to FIG. First, the overall control unit 1 checks the entity I of the replica document in the document management system that can be edited from the document information management unit.
D and the document ID are detected (step S131), and the registration date and time confirmation processing shown in FIG. 14 described above is performed on the document including the replica document (step S132).

Next, the overall control means 1 detects whether or not the entity of the replica exists in the document management system (step S133). If there is no entity, nothing is performed. Detects whether a predetermined period or more has elapsed since the registration / change date and time of the document of the replica (step S134), and if it has elapsed, the document of the replica has already been used for editing. Since it is considered that there is no such document, the document entity of the replica is deleted by the document management system (step S135), and the above process is repeated for all replica documents stored in other editable document management systems. Performed (step S136). As described above, it is possible to delete a replica document that is not used among the managed documents, and it is possible to improve the storage efficiency of the document management system.

This processing is performed by the administrator account supe.
r, the documents of the replica corresponding to the above-described deletion conditions are surely deleted. However, since the documents of these replicas are created by the integrated document management apparatus, there is no problem in deleting them. . For example, a document registered independently of the document management system is managed as an original in the document management system, and there is no problem. Further, since the latest original document of the document is stored in the document management system D by the above-described registration date / time confirmation processing, there is no problem.

Here, as the predetermined period serving as a reference for determining whether or not the document has been used for the above-mentioned editing, for example, an arbitrary period in which the editing is considered to have been completed may be set.
It can be set to infinity. When set to infinity, the same document always exists in the document management system D and the document management system having the document editing function, and the storage capacity is doubled. The response speed for the editing function is faster than when another period is set.

Next, an operation in which the integrated document management apparatus itself detects and registers a document not managed by itself from the documents managed by the document management system will be described with reference to FIG. First, a plurality of document search systems are searched for a document associated with a registration / change date and time after the time when the overall control unit 1 last performed the process (step S141), and the document obtained by the search is retrieved. Then, the management ID of each document management system is received, and the entity ID combined with the system ID of each document management system is added to the candidate list (step S142).

Next, the overall control means 1 extracts one entity ID from the candidate list (step S143) and refers to the document information management means 3 to detect whether or not the entity ID is managed (step S144). , S145).
As a result, if the document is not managed, it means that the document is stored uniquely in the document management system and is not managed by the integrated document management device. Let D copy
Full-text search can be performed quickly (step S14)
At the same time as 6), the document is given a new document ID and registered in the document information management means 3 to make the document usable in the integrated document management device (step S14).
7). Note that nothing is performed if it is managed. Then, the above processing is performed for all entity IDs in the candidate list.
(Step S148).

Therefore, a document in which a new document is registered independently of the document management system can be registered in the integrated document management device, and can be used by the integrated management device. Note that the above process is performed for the administrator account su
This is performed in per, but only for document retrieval processing, and does not adversely affect the original such as deleting the original document in each document management system.

In the above-described embodiment, a document management system can be newly added or deleted only by rewriting information in the document management system information management means 3. Even a document management system that manages documents can be added.

Further, in the above-described embodiment, an example has been described in which a document management system having an advanced editing function and a document management system for high-speed full-text search are effectively used in an integrated manner. However, the present invention is not limited to this. Any document management system can be effectively used in an integrated manner.

Each of the functional units described above is configured by executing a control program (previously stored in a ROM, a RAM, or the like) by a processor. In the present invention, these functional units are configured as independent hardware circuits. May be. In addition, the present invention allows the control program to be grasped as a computer-readable storage medium such as a floppy disk or a CD-ROM, and reads the control program from the storage medium and causes a processor to execute the control program. Such processing can also be executed.
