Abstract: The present disclosure provides a document collaboration method, which applies a plurality of clients to process a document located on a server collaboratively. The document comprises a plurality of document fragments. The document collaboration method comprises the following steps: each client selects a document fragment which has not been selected by other clients in the document to edit, and sends the edited data relevant to the document to the server; and, the server forwards the data to other clients. Compared with the prior art, the document collaboration method in the present disclosure has the following advantages that a collaboration document is divided into several document fragments, and only one client has an exclusive permission to edit the document fragments at a same moment, thus no conflict will be caused when a plurality of users modify the same content.
