Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a database management device capable of knowing the order from an original document to a copied document.

[0002]

2. Description of the Related Art Conventional electronic documents store documents in a hierarchical structure and store the document name as search information in a database. Therefore, when the user wants to search for a desired document, he or she inputs the document name as the search information, and the document is searched.

There is also a document which is provided with a user-defined attribute or a link attribute so that the user can easily find a desired document (for example, Japanese Patent Laid-Open No. 62-160549).
JP-A-63-156256).

[0004]

In some cases, after a duplicate document is created from an original document, a part of the duplicate document is further modified to create another new document. When a new document is created from a duplicate document in this way, document creation efficiency is improved. However, after being duplicated several times from the original document,
The duplication makes it difficult to identify and retrieve the original document for the newly created document. Further, it is impossible to extract all the group of documents that have been repeatedly changed while copying. If there is no means to search the original document, and if the contents of all the group of documents that have undergone changes while copying must be changed, the group of documents cannot be completely searched. ,
Therefore, the content of the document cannot be easily changed. Furthermore, when many similar documents are created by duplicating the original document and changing the contents partially, it may be possible to discard the documents in the middle, but search for all those similar documents without exception. Since it cannot be displayed to the user, the document to be discarded cannot be specified and therefore remains undiscarded, which causes a problem of waste of the database.

The present invention is intended to solve the above problems, and since the copy document group created by partially changing the original document or the content of the copy document is changed,
It is an object of the present invention to provide a database management device that can easily and completely search for a document group whose contents need to be changed. Another object of the present invention is to provide a database management device capable of supporting the judgment of document destruction by clarifying the derivation order of a duplicate document created by partially modifying the original document. To do.

[0006]

In order to achieve the above object, the database processing apparatus of the present invention represents a duplication relationship between a new document created by duplication and the original document. A link information table (181 in FIG. 1) for storing link information and a link information registration means for registering, when a new document is created by duplication, link information indicating the relationship of duplication in the link information table (181). (192 in FIG. 1) and when the history display of the duplication is designated together with the designation of the document to be searched, the link information table (181) is searched and all the documents linked to the designated document and those Copy history display processing means (19 in FIG. 1) for reading and displaying information indicating the link relationship between documents.
3) and.

[0007]

[Operation] When a user creates a duplicated document from an original document, the user inputs document attribute information such as a document name given to the document, and instructs the process of creating a link relationship.
In response to this instruction, the link information registration means creates link information indicating a duplication relationship between the new document created by duplication and the document that is the origin of the duplication. Further, the link information registration means is a process for registering, in the database link information table, link information indicating a duplication relationship between a new document created by duplication and a document that is a duplication source. I do. When the user duplicates a document and wants to know the history of the document, the user gives an instruction to display the history of the document. In response to this instruction, the link information search means searches the link information in the link information table in the database and also reads all the documents linked to the specified document and the information indicating the link relationship between those documents. .. Then, the copy history display processing means performs processing for displaying, on the display device, the copy relationship between the new document created by the copy and the document that is the copy source, based on the link information. .. Based on the processing of the copy history display processing means, history information of all the instructed documents is displayed as a list on the display device. As described above, the relationship between the document copied from the original document is displayed so as to be understood so that the user can see the document and know the document that needs to be changed. Further, the user can easily determine the discarding of the unnecessary document when the link relationship between the original document and the copied document is known.
