[0015]
【Example】
Hereinafter, an embodiment of a filing system according to the present invention will be described with reference to the drawings.
[0016]
FIG. 1 is a block diagram showing the overall configuration of the filing system.
[0017]
As shown in FIG. 1, the filing system includes a client control unit 11, clients 12a to 12d, and servers 13a to 13c.
[0018]
Here, the clients 12 a to 12 d are clients that handle workstations (WS) and the like, and are connected to the client control unit 11.
[0019]
The clients 12a to 12d can make file registration, search, and retrieval requests to the servers 13a to 13c and the client control unit 11, and make access requests to any of the servers via the client control unit 11. It will be.
[0020]
The servers 13a to 13c are file servers that manage files registered from the clients 12a to 12d, and are connected to the client control unit 11, respectively.
[0021]
The client control unit 11 constituting the subject of the present invention is provided between the clients 12a to 12d and the servers 13a to 13d. The client access unit 11a, the schema management unit 11b, the file operation unit 11c, and the server access It comprises a section 11d and a local disk 11e. The client control unit 11 also functions as a file server that performs file management using the local disk 11e.
[0022]
The client access unit 11a receives file registration, search, and retrieval requests from the clients 12a to 12d, outputs the requests to the schema management unit 11b, and sends the search results received from the schema management unit 11b to the requesting client. Output.
[0023]
The client access unit 11a is equipped with existing protocols used by various clients in addition to the standard protocol adapted to the function of the system.
[0024]
In other words, before using the client control unit 11, each client 12a to 12d equips the client access unit 11a with the existing protocol used with the servers 13a to 13c.
[0025]
The schema management unit 11b is a management unit that manages a plurality of schemas having different attribute items. That is, the client control unit 11 is configured so that the local disk 11e can be described in a plurality of forms using a plurality of schemas, and the schema management unit 11b manages the plurality of schemas.
[0026]
The file operation unit 11c manages and operates multimedia data files using content data (hereinafter referred to as “content”) and attribute information. Specifically, a schema corresponding to the requested search condition or the like is selected, and a file operation is performed using the reference pointer.
[0027]
This reference pointer is a kind of address pointer indicating the storage location of the contents, and is an extension of the concept of a conventionally used address pointer.
[0028]
That is, in the conventional address pointer, the storage location of the file is indicated with the inside of the local disk 11e as the target range, but this reference pointer does not stay within the local disk 11e but also the target range of the other servers 13a to 13c. It is said.
[0029]
In addition, this reference pointer does not target only the storage medium storing the file, but also the physical position. Specifically, it is possible to use a reference pointer to point to a library or a book shelf in which these books and the like are located, with prints and books as management targets.
[0030]
The server access unit 11d is a part that controls the interface between the client control unit 11 and the servers 13a to 13c. Like the client access unit, the server access unit 11d is equipped with existing protocols used by the various servers 13a to 13c in addition to the standard protocol. .
[0031]
By using the client control unit 11 having the above-described configuration and functioning also as a server, the client control unit 11 can be positioned as an upper server of the servers 13a to 13c, and a file management function of each server can be integrated to realize a filing system. .
[0032]
Next, a file storage / retrieval procedure using the filing system having the above configuration will be described with reference to FIG.
[0033]
First, a case where a document file is stored from the client 12a to the server 13b will be described.
[0034]
When the client 12a makes a document file storage request to the server 13b using the existing protocol (S201), the client access unit 11a accepts the request and outputs it to the schema management unit 11b (S202). In response to the storage request, the schema management unit 11b selects a schema based on the attribute data of the document file, and confirms the storage location of the document file in the schema. Then, the document file is output to the file operation unit 11c together with the storage position (S203).
[0035]
Then, the file operation unit 11c creates file management attribute information based on the attribute data of the document file, stores this attribute information in a predetermined storage location, and sends the document file to the server access unit 11d ( S204).
[0036]
The attribute information created here is obtained by adding a reference pointer indicating the storage location of the document file to the attribute data of the document file. In this case, information corresponding to the server 13b is used as the reference pointer. .
[0037]
Then, the server access unit 11d transmits the document file to the server 13b using the existing protocol (S205), and the document file is stored in the server 13b.
[0038]
If the server 13b completes the storage of the document file, a storage completion notification is transmitted to the server access unit 11d (S206). Then, the storage completion notification is sequentially transferred to the file operation unit 11c, the schema management unit 11b, and the client access unit 11a (S207), and stored in the client 12a that has requested storage of the document file from the client access unit 11a. A completion notification is output using the existing protocol (S208).
[0039]
By performing the above storage processing, not only the document file is stored in the server 13b as requested by the client 12a, but also the file operation unit 11c can recognize that the document file is stored in the server 13b. Become.
[0040]
Since the client 12a and the server 13b can transfer and receive files in the conventional procedure using an existing protocol, the client control unit 11 does not need to be modified with the introduction of the client control unit 11. It can be regarded as (transparent).
[0041]
Next, a processing procedure when a file search request is made from the client 12b to the client control unit 11 will be described.
[0042]
When the client 12b makes a file search request to the client control unit 11 using a standard protocol (S211), the client access unit 11a accepts this request and outputs it to the schema management unit 11b (S212). In response to the search request, the schema management unit 11b selects a schema that matches the search condition and outputs it to the file operation unit 11c together with the search condition (S213).
[0043]
Then, the file operation unit 11b searches for attribute information that matches the search condition in accordance with the schema, and outputs information about the corresponding file to the schema management unit 11b as a search result (S214).
[0044]
At this time, since each attribute information is provided with a reference pointer indicating the storage location of the file, the storage location of the file that matches the search condition can also be included in the search result.
[0045]
Then, this search result is output to the client 12b using the standard protocol via the schema management unit 11c and the client access unit 11a (S215, S216).
[0046]
By performing the search process, a file that matches the search request of the client 12a can be searched and output not only in the client control unit 11 but also in the servers 13a to 13c.
[0047]
The outline configuration and the outline of the processing of the filing system according to the present invention have been described above. Hereinafter, the client, the server, and the client control unit are specifically described using the second embodiment when connected to the network. explain.
[0048]
FIG. 3 is a block diagram showing the system configuration of the filing system in the second embodiment.
[0049]
As shown in FIG. 3, in the second embodiment, clients 12a to 12c equipped with a workstation (WS), a personal computer (PS), and a scanner (Scan) are connected via a LAN 21 (local area network). A facsimile (FAX) client is connected to the client control unit 11 via a FAX line means.
[0050]
The client control unit 11 is connected to the external servers 13a and 13b via the LAN 22. It is assumed that this external server is a file server that performs file management, as in the previous example.
[0051]
In this embodiment, the LAN 21 and the LAN 22 are provided separately for convenience of explanation, but can be connected to the same LAN.
[0052]
As in the previous embodiment, the client control unit 11 includes a client access unit 11a, a schema management unit 11b, a file operation unit 11c, a server access unit 11d, and a local disk 11e.
[0053]
Here, in this embodiment, the client access unit 11a includes a local media access unit A1, a network access unit A2, and a FAX line access unit A3.
[0054]
The local media access unit A1 receives a file registration request or the like from local media such as a floppy disk device (not shown) provided in the client control unit 11.
[0055]
The network access unit A2 receives access requests from the clients 12a to 12c connected via the LAN 21.
[0056]
The FAX line access unit A3 accepts an access request from a client that accesses the client control unit 11 using a FAX line unit. In this case, the access from the FAX client 12d using the FAX line unit is performed. The request is accepted by the FAX line access unit A3.
[0057]
Each of the access units A1 to A3 can be equipped with a plurality of protocols, and an existing protocol or the like can be used in addition to the standard protocol for the client control unit.
[0058]
The schema management unit 11b manages a plurality of schemas such as the schema B1 and the schema B2. For example, when storing a file, refer to the attribute of the file and select a schema that matches the attribute. become. The contents of this schema will be described later.
[0059]
Next, the file operation unit 11c includes a content processing unit C1 and an attribute processing unit C2. In this embodiment, a case will be described in which a file is divided into contents and attributes, the contents are stored in a predetermined server, and the attributes are handled in the file operation unit 11c.
[0060]
The content processing unit C1 processes the content of the file. Specifically, the content processing unit C1 determines a storage location for storing the content and instructs the server access unit 11c to store the content in the storage location. It is. As a result, the contents of the file are stored in the server 13a or 13b or the local disk 11e. When the client specifies an external server to be stored, the specification of the external server is followed.
[0061]
The attribute processing unit C2 adds an attribute using the storage location determined by the content processing unit C1 as a reference pointer, and stores the attribute or the like in a management table (not shown) corresponding to the schema. This management table is provided for each schema.
[0062]
Next, the server access unit 11d includes a local disk access unit D1 and a network access unit D2.
[0063]
The local disk access unit D1 is used when the client control unit 11 functions as a server, and accesses the local disk 11e.
[0064]
The network access unit D2 is used when accessing the external server 13a or 13b via the LAN 22. The network access unit D2 can be equipped with an existing protocol in addition to the standard protocol.
[0065]
Next, file registration, retrieval, and retrieval processing performed by the client control unit 11 having the above-described configuration will be specifically described.
[0066]
FIG. 4 is a flowchart showing the flow of file registration processing of the client control unit 11 shown in FIG.
[0067]
As shown in FIG. 4, when a file registration request is received from a client using a predetermined protocol, the protocol is interpreted (S401), the request is received from the corresponding access unit A1 to A3, and the schema management unit 11b receives the request. Output.
[0068]
Then, the schema management unit 11b extracts attributes and contents from the file that has received the registration request (S402), and matches the information required for each schema management structure (hereinafter referred to as "schema information") with the attributes of the file. If there is no corresponding schema, an error end notification is sent to the client (S404), and the process ends. At this time, a schema corresponding to the file can be newly constructed.
[0069]
On the other hand, if a schema corresponding to the attribute of the file exists, the content and attribute of the file are sent to the file operation unit 11c after the schema is fixed.
[0070]
In the file operation unit 11c, first, the content processing unit C1 determines a storage location for storing the content of the file, and notifies the attribute processing unit C2. If the client specifies a storage destination server, the specification is followed.
[0071]
Upon receiving this notification, the attribute processing unit C2 adds the storage location of the content data to the attribute as a reference pointer, adds it to a predetermined position of the schema, and stores it in a management table (not shown) (S405).
[0072]
Next, it is confirmed whether or not the storage of this attribute has been completed normally (S406). If the storage has been completed normally, the server access unit 11d is asked to store the contents of the file in the determined storage location. Instruct.
[0073]
The server access unit 11d uses the local disk access unit D1 when the storage location is the local disk, and uses the external server access unit D2 when the storage location is the external server 13a or 13b. The contents of the file are stored (S407).
[0074]
Then, it is confirmed whether or not the content of this file has been stored normally (S408). If the file has been stored normally, the client is notified of the normal end (S409), and the process ends. .
[0075]
In S406 and S408, if the process is not completed normally, an error end notification is sent to the client (S404), and then the process ends.
[0076]
Next, the file search process will be described with reference to the flowchart shown in FIG.
[0077]
FIG. 5 is a flowchart showing the flow of the file search process of the client control unit 11 shown in FIG.
[0078]
As shown in FIG. 5, when a search request is received from the clients 12a to 12d, the client access unit 11a interprets the protocol (S501) and accepts the search request from the corresponding access unit as in the above registration process. And sent to the schema management unit 11b.
[0079]
Then, the schema management unit 11b extracts a search range and a search condition from the search request (S502), and checks whether there is a schema corresponding to the search condition or the like by checking each schema information (S503).
[0080]
If there is no schema that matches the search conditions, the search result is notified to the client that there is no corresponding file (S506), and the process ends.
[0081]
On the other hand, if the corresponding schema exists, the search condition and the like are sent to the file operation unit 11c.
[0082]
Then, the file operation unit 11c uses the attribute processing unit C2 to search for files having attributes that match the search conditions (S504), aggregate the search results (S505), and notify the search results to the client. (S506) and the process ends.
[0083]
Next, the file extraction process will be described with reference to the flowchart shown in FIG.
[0084]
FIG. 6 is a flowchart showing the flow of file retrieval processing of the client control unit 11 shown in FIG.
[0085]
As shown in FIG. 6, when a file retrieval request is received from the clients 12a to 12d, the protocol is interpreted in the client access unit 11a (S601), and the retrieval request is issued from the corresponding access unit, as in the registration process. Is sent to the schema management unit 11b.
[0086]
Then, in the schema management unit 11b, information corresponding to the attribute of the file to be extracted is extracted from the extraction request (S602) and collated with each schema information (S603).
[0087]
As a result, if there is no corresponding schema, an error end notification is sent to the client (S604), and the process ends.
[0088]
On the other hand, if the corresponding schema exists, the file retrieval request is output to the file operation unit 11c.
[0089]
The file operation unit 11c that has received the extraction request uses the attribute processing unit C2 to extract an attribute that matches the extraction request (S605).
[0090]
Then, it is confirmed whether or not the extraction of the attribute has been normally completed (S606). When the extraction has been completed normally, the reference pointer is extracted from the attribute and the storage location of the file is confirmed.
[0091]
Then, the contents are extracted from the storage location pointed to by the reference pointer (S607). If the extraction is completed normally (S608), the contents and attributes are transferred to the client (S609), and the process is terminated.
[0092]
As described above, by performing file storage, retrieval, and retrieval processing, file management can be performed without distinguishing the external servers 13a and 13b from the local disk 11e.
[0093]
Next, the structure of each schema used in the schema management unit 11b will be described.
[0094]
FIG. 7 is a conceptual diagram showing a schema structure.
[0095]
As shown in FIG. 7, the schema management unit 11b includes a plurality of schemas such as a schema B1 and a schema B2.
[0096]
Each schema manages each attribute in a tree structure. For example, attribute 71 and attribute 72 are arranged under schema B1, and attribute 71a and attribute 71b are arranged under attribute 71.
[0097]
In this way, by using a tree-structured schema, a schema with high search efficiency can be realized.
[0098]
The schema that can be handled in the present invention is not limited to a tree structure, and schemas having various structures can be used.
[0099]
In the schema management unit 11b, schemas can be freely added and deleted.
[0100]
Next, a specific example of the schema management unit 11b will be described with reference to FIG.
[0101]
As shown in FIG. 8, the schema management unit 11b includes schema B1 and schema B2.
[0102]
Here, the schema B1 is characterized by schema information B10 having a creation date with a date as a type, a creator with a character string as a type, and a document format with a number as a type as items. The schema B2 is a schema characterized by schema information B20 having items of an issue date having a date as a type, a slip type having a number as a type, and a customer having a character string as a type.
[0103]
Further, the attributes constituting each schema have specific values for each component of the schema information. For example, “930824” is set as the creation date in the attribute 81 arranged in the schema B1. “Yamaguchi” is stored as the creator, and “1” is stored as the document format.
[0104]
Further, the attribute stores a reference pointer that points to the storage location of the content, for example, as the content pointer 810a is added to the attribute 81.
[0105]
This reference pointer can not only indicate the address in the local disk of the server, but also includes an external server and a physical archive.
[0106]
That is, in the conventional database or the like, one schema is set for one database. In the present invention, the schema management unit 11b manages a plurality of schemas having different attribute items, In contrast to the conventional address pointer that indicates the storage location in the local disk, in the present invention, a reference pointer that can point to an external server, a physical archive, or the like is provided in the attribute.
[0107]
Next, the relationship between the management form in the schema management unit 11b and the display screen of the WS client will be described with reference to FIG.
[0108]
As shown in FIG. 9, drawers 91 and 92 are displayed on the screen of the WS client for each of the schemas B1 and B2 of the schema management unit 11b.
[0109]
The attributes 81 and 82 arranged in the schema B1 are displayed as cabinets in the drawer 91, and the attributes 81a and 81b arranged under the attributes 81 are displayed as documents.
[0110]
In this way, by providing a drawer for each schema and arranging attributes corresponding to folders and documents in the drawer, the structure of each schema can be displayed on the workstation and specified by the client. .
[0111]
As described above, in the present embodiment, since the schema management unit 11b is configured to manage a plurality of schemas, file management can be performed using a plurality of management structures.
[0112]
Further, since the file operation unit 11c is configured to point not only to the files in the local disk 11e but also to the external servers 13a to 13c and the bookshelf by the reference pointer, the files stored in the external server or the like can be integratedly managed. it can.
[0113]
Further, since the client access unit 11a is configured to accept an access request input from the clients 12a to 12d using a plurality of protocols, an access request can be made using an existing protocol as well as a standard protocol. it can.
[0114]
In this embodiment, a file server is targeted as an external server. However, the present invention is not limited to this, and can be applied to various devices that manage files such as databases and mail servers. is there.
[0115]
【The invention's effect】
As described above in detail, according to the present invention, the schema management unit is configured to manage a plurality of schemas having different attribute items, so that file management can be performed using a plurality of management structures. Become.
[0116]
In addition, since the client can access with the same protocol as the server, there is an effect that it is transparent.
