Abstract

PURPOSE:To conveniently control the input/output operations of plural main body files including the different types of storages by putting a main body file identifier into a retrieving attribute and selecting the desired one of those main body files. CONSTITUTION:The file names, the stored medium names, etc., of a main body file 3 are registered in a document control file 1 as the control information on the file 3. A desired file 3 is searched by reference to the file 1 and the document data 5 are registered in a prescribed address. Then an access is applied to an attribute file 2 for registration of the retrieving attribute information 6, i.e., the information including a main body file identifier 8. When a document is taken out, an access is applied to the file 2 by reference to the file 1. Then an access file 3 is decided by the identifier 8. Thus the documents are easily registered into plural storages including the different types of storages.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a document management system that manages documents using a computer.

[Prior Art] FIG. 4 is a block diagram showing an example of a conventional document management system, in which (1) indicates a document management file, (
2) is an attribute file, (3) is a main file, (4) is an attribute substitute key file, (5) is document data, and (6) is an attribute.

FIG. 5 is a flowchart showing the operation of the system of FIG. 4 when registering a document, and (50) to (53) indicate each step. In other words, the document data to be registered (
5) to the specified address in the main file (3),
Save the search attribute information of the document (6) to the attribute file (2)
(52).

FIG. 6 is a flowchart showing the operation of the system of FIG. 4 when retrieving a document, and (60) to (63) indicate each step. That is, the document management file (
1), access the attribute file (2) according to the attributes of the document to be retrieved, retrieve the target record according to the search information of the document (61), and access the main file (3) using the pointer in this target record. Step (6) of extracting the target document data (5)
2).

The attribute substitute key file (4) is used in place of the attribute file (2) in order to search for the target document data (5) at high speed using the keyword of each document data when the keyword can be used.

[Problems to be Solved by the Invention] Since the conventional document management system as described above is configured as described above, the code for identifying the main file is not included in the search attribute information. Therefore, the main file must be treated as a single file,
In particular, when the main file contains different types of files, such as files on a magnetic disk and files on an optical disk, it is difficult to handle these different types of files as a single main file. There was a point.

The present invention was made to solve this problem, and aims to provide a document management system that can conveniently manage input/output to a plurality of main files including different types of main files.

[Means for Solving the Problems] The document management system according to the present invention includes a main file identifier in the search attributes so that a target main file can be selected from among a plurality of main files using this identifier. .

[Operation] In the document management system of the present invention, a target main file can be easily selected from a plurality of main files, so a system using a large number of main files can be configured.

[Examples] Examples of the present invention will be described below with reference to the drawings. 1st
The figure is a block diagram showing an embodiment of the present invention. In the figure, the same reference numerals as in FIG. 4 indicate the same or corresponding parts, (7)
is the additional main file registration area in the document management file (1), (8) is the main file identifier, and (9) is the main file of the optical disc.

FIG. 2 is a flowchart showing the operation of the system of the present invention at the time of document registration, and (20) to (26) indicate each step. In other words, the document management file (1
), register the file name and storage medium name of the main file as management information of the main file, and after deciding which main file should contain the document data, in step (21), save the document management file. Step (22>) refers to the target main file and displays the heading. Step (22) registers the document data at a predetermined address of the main file. Step (23) refers to the document management file and displays the heading in the attribute file. In step (24), access the location where attributes corresponding to the attributes of the registered document data are registered.
, enter the search attribute information (main file identifier (8) at that location).
)).

FIG. 3 is a flowchart showing the operation of the system of the present invention when retrieving a document, and (30) to (36) indicate each step. In other words, the document management file (
Step (31) refers to the attribute file 1) and accesses the attribute file 2), retrieves the record in which the search attribute information (6) of 5) is stored in the target document data according to the search information, step (32), The main file to be accessed is determined based on the main file identifier (8) of the retrieved record, and in steps (33) to (34), the determined main file is accessed using the pointer in the record.

In addition, in the above explanation, this invention is explained as a document management system that manages document data (5), but it is not only possible to manage document data (5), but also to manage each set of data,
It goes without saying that the present invention can be used in systems that generally register information such as image data and program sources, and since the document management file (1) only needs to contain information generated by the system, Any type of storage device such as a magnetic disk may be used.

Furthermore, one area of the memory may be used as the document management file (1), and identification information indicating that the area constitutes the document management file (1) may be added.

[Effects of the Invention] As explained above, the present invention has the advantage that it is easy to register documents in multiple storage devices including different types of storage devices, and therefore it is possible to easily register and manage a large amount of document data. There is.

[Brief explanation of the drawing]

FIG. 1 is a block diagram showing an embodiment of the invention, FIG. 2 is a flowchart showing the operation of the system of the invention when registering a document, and FIG. 3 is a flowchart showing the operation of the system of the invention when retrieving a document. , FIG. 4 is a block diagram showing a conventional system, FIG. 5 is a flowchart showing the operation of the system shown in FIG. 4 when registering a document, and FIG. 6 is a flowchart showing the operation of the system shown in FIG. 4 when retrieving a document. It is. In the figure, (1) is the document management file, (2) is the attribute file, (3) is the main file, (5) is the document data,
(6) shows the search attribute information, (7) shows the additional main file registration area, (8) shows the main file identifier, and (9) shows the main file of the optical disc. Note that the same reference numerals in each figure indicate the same or corresponding parts.

Claims (1)

[Claims] A plurality of main files constituted by a plurality of storage devices including disparate storage devices using different types of storage media;
