Abstract

PURPOSE:To eliminate a need of learning of document data editing functions and to synchronize editing with the data base processing of data other than document data by designating an editor which a user is accustomed to use and placing it under the control of a data base system even during editing of document data. CONSTITUTION:A document editing means 5 edits document data called by a data processing means 2, and a data base access means 6 is called by the data processing means 2 and a document data editing means 5 to retrieve, update, add, and delete the data base. A document data converting means 8 is called by the document data editing means 5 and converts document data retrieved from the data base to a form adapted to a document editing program 9 and converts it to a data base internal form for the purpose of generating a document file 11 to storing data of the document file 11 edited by the document editing program 9 in a data base file 7. The document is edited by the document editing program 9. Thus, learning of document data editing functions is unnecessary and editing is synchronized with the data base processing of data other than documents.

If the file formats of the data before and after conversion are not the same, the file formats of the data are converted (step 506) and the process ends.

〔Effect of the invention〕

According to the present invention, a user can edit document data in a database by specifying an editor with which he or she is familiar, thereby eliminating the need to learn how to use a new document editing program or editing function.

Further, since the document data is under the control of the database system even while editing the document data, simultaneous access to the document data can be managed by the database system, and therefore, unauthorized updating of the document data when multiple users access the document data can be prevented. Note that synchronization with database processing other than document data is also guaranteed.

Furthermore, by adopting a method of calling the conversion program internally, it is easy to add a conversion program, and by adding a conversion program, various document editing programs can be used.
