EXAMPLES Examples of the present invention will be described below.

FIG. 1 is a block diagram of a file management apparatus according to an embodiment of the present invention, in which 1 is a central processing unit (hereinafter referred to as CPU) for controlling the apparatus and data processing, and 2 is a program or the like. It is a read-only memory (hereinafter referred to as ROM) that is stored. CPU1 operates according to the program in ROM2. 3 is a random access memory (hereinafter referred to as RAM) that stores various data, 4 is an input unit such as a keyboard and mouse, and 5 is a large storage unit that stores document data by a mass storage medium such as a magneto-optical disk that stores the document data. Capacitive storage device, 6 is a display device,
Reference numeral 7 is a printer, and 8 is an image input device.

The document data stored in the mass storage device 5 is managed in association with a predetermined classification name. In the present embodiment, management is performed in three layers of large classification, middle classification, and small classification.

The mass storage device 5 has a structure shown in FIG.
As shown in FIG. 3, a database management area 21 for managing information about classification and a document storage area 22 for storing document data are set. In the document storage area 22, a document management table 23 and a document data storage unit 24 are set. It is provided.

In the database management area 21, node data as shown in FIG. 4 is provided for each classification name of large classification, middle classification and small classification. Further, as shown in FIG. 5, document management data is provided for each document in the document management table 23, and the document data in the document data storage unit 24 is specified by the pointer in the document management data.

The node data is node id / parent node i
d, first child node id, elder brother node id, younger brother node id,
It consists of node name (classification name), and node id is large, medium,
Serial numbers are automatically assigned in the order of registration of classifications regardless of size. In addition, the parent node id is the node id of the node of the upper hierarchy to which the node belongs, and the first child node id is the node id of the node registered first among the nodes of the lower hierarchy that belongs to that node. However, in the node data of the node in the lowest hierarchy (small classification), the first child node id stores the document id (described later) of the document registered first among the documents belonging to that node. To be done. In addition, the parent node id of the highest-level node (major classification) is “0”.

Among the older brother node id and the younger brother node id that belong to the same upper layer node as that node, the node ID registered immediately before the node and the node ID registered immediately after the node are stored. The brother node id is "0" for the registered node, and the brother node id is "0" for the last registered node.

In this embodiment, a hierarchical structure shown by the tree 31 and the tree 32 in FIG. 2 is used.

As shown in FIG. 5, the document management data consists of a document id, a parent node id, a brother document id, a brother document id, a document name, and a pointer to document data. The document ids are serialized in the order of document registration. The number will be assigned automatically. This document id is distinguished from the node id by, for example, making a specific bit of the byte different from the node id. Parent node i
The node id of the node (small category) to which the document belongs in d
However, in the older brother document id, the document i of the document that belongs to the same node (small classification) as the document and is registered immediately before the document i
d is the younger brother document id, and the document id of the document that belongs to the same node (small classification) as the document and is registered immediately after the document is stored. However, when the document is first registered for the node (small classification), the brother document id in the document management data is “0”, and when it is the last registered document. The younger brother document id in the document management data is “0”. The parent node id, the older brother document id, and the younger brother document id have a plurality of areas from the first to the third so that one document can be assigned to a plurality of classifications (hereinafter, the first document management). Information 101, second document management information 102, and third document management information 103). These pieces of document management information are not limited to three as in the present embodiment, and the document management data may have a variable length and an area may be secured as necessary.

When the hierarchical structure of classification is the tree 32 shown in FIG. 2, the inside of the database management area 21 is as shown in FIG. In FIG. 6, the node data 71 corresponds to the node 32-1 in FIG. Below, node data 7
2 to the node 32-2, node data 73 to the node 32
-4, the node data 74 corresponds to the node 32-5, the node data 75 corresponds to the node 32-3, and the node data 76 corresponds to the node 32-6. For example, node 32
In the case of the "technical report" of -2, the node data 72 corresponding to it is node id "6", parent node id "5" (node data 71, node 32-1), first child node id "7" (node data 73, node 32-
4), brother node id is "0", brother node id is "9"
(Node data 75, node 32-3).

The operation of registering a document in the document management apparatus of the present embodiment configured as described above will be described below with reference to the flowcharts of FIGS. 8 to 9.

First, in step 1, when a read command is issued from the CPU 1 to the image input device 8, the image input device 8 optically reads a predetermined document. C
After writing the read image data into the RAM 3 in step 2, the PU 1 sets new document management data in the document management table 24 in the mass storage device 5 in step 3. At this time, the latest serial number is set in the document id, and "0" is set in the parent node id / elder brother document id / younger brother document id.

After setting the document management data, the CPU 1 waits for the input of the document name from the input unit 4 in step 4, and when the document name is input, the input document name is set in step 5 in step 3. Register to document management data.

When the document name is registered, the CPU 1 performs the classification setting process for the document by the process of step 6 (steps 11 to 25).

The classification setting process will be described below.
In step 11, the CPU 1 initializes a counter n (not shown) in the RAM 3 to "1", and executes step 1
In step 2, the designation of the classification from the input unit 4 is awaited. At this time, the CPU 1 displays a tree as shown in FIG. 2 on the display device 6. Looking at this tree display, the operator designates the classification by using the input unit 4 and designating the small classification for registering the document with a cursor or the like.

When the classification is designated in step 12, the CPU 1 proceeds to step 12 in step 13.
The database management area 21 is searched for the node data of the classification designated by. Then, in step 14,
First child document id of node data searched in step 13
Is "0", and if it is "0", the document is not yet registered in that category. Therefore, the classification setting process for the document is performed in steps 15 and 16, and "0" is set.
If not, another document is already registered in that category, and therefore the processes in and after step 17 are performed.

In step 15, the value of the document id of the document management data set in step 3 is registered in the first child document id of the node data retrieved in step 13. In step 16, the node id of the node data of the classification specified in step 12 is registered in the parent node id of the nth classification information of the document management data set in step 3.

In step 17, the document management table 23 is searched for the document management data pointed to by the first child node id of the node data of the classification specified in step 12. Then, in step 18, the value of the younger brother document id of the corresponding document management data is checked, and if it is not "0", step 1
In 9, the document management data pointed to by the younger brother document id checked in step 18 is checked, and the process of step 18 is performed again.

When the document management data in which the value of the younger brother document id is "0" is found in step 18, for the nth classification information of the document management data set in step 3, the parent node id is set to step 12 in step 20. In step 21, the brother document id is set to the value of the node data of the node data designated in step 21 and the value of the document id of the document management data corresponding to the condition of step 18 is set, and in step 22, the condition of step 18 is set to the condition. The younger brother document id of the nth classification information of the corresponding document management data is set to the value of the document id of the document management data set in step 3.

When the classification information of the image data to be newly registered is set in the processing of step 15 to step 16 or step 17 to step 22, the CPU 1
In step 23, the value of the counter n is updated by +1, and in step 24, it is checked whether n is 3 or less (in this embodiment, 3 is set for one document data.
It is possible to add up to three categories).

If the number of classifications is up to two and the operator desires to add another classification (step 25),
The processing from step 12 onward is performed again.

After the classification is set, in step 7, the CPU 1 records the image data in the RAM 3 in the document data storage unit 25, and in step 8, the writing destination address is stored in the corresponding document management data. register.

Nodes 32-4 and 32-6, which are sub-classifications of classification having a structure like the tree 32 shown in FIG.
When a document with the document name "report" is registered in, the document management data is as shown in FIG.

When the registered document data is searched in the above document management device, the first child node id in the node data of the designated classification and the document management data indicated by the first child node id A list of documents belonging to the specified classification can be obtained from the younger brother node id.
Further, when the retrieved document data is deleted, the contents of the node data of the classification to which the document to be deleted belongs can be appropriately changed from the first, second and third classification information of the document management data.

As described above, in the present embodiment, a plurality of independent classifications can be given to one document, so that appropriate classification can be performed even for document data for which it is somewhat difficult to apply only one classification. It is possible to register by doing so, and the flexibility of hierarchical document management is expanded. In addition, even one document with multiple classifications is apparently processed in the same way as other documents registered separately for each classification, so the management system of the document is clear and easy to understand, and The minimum memory capacity is required.

[0032]

The present invention has means for hierarchically managing document data based on predetermined classification information and having means for associating a plurality of classification information with document data, so that the management system is clear and easy to understand. In addition, it is possible to realize a document management device that can perform flexible document management.
