Abstract: Provided are an apparatus and a method that differently sets the access authority of a user for individual parts of an online document. For every parts of the online document, the user authority is set and the parts are edited only by a user that can access the part. Finally, the parts of the documents are combined as the final document. According to the present invention, the document is divided into parts and the access authority of the user is variously set, which results in maximizing the efficiency of editing the document. The editors of the individual parts inherit the authorities to other people, so that it is very efficient for the cooperative job of a document in the organization having a hierarchy.
