Abstract

The invention discloses a method for controlling an edition of a document of an extensive makeup language (XML) database. According to the technical scheme, the efficient maintenance of data in all editions of an XML document in an XML database management system is realized. In the XML document, just a node which is updated is copied, updated and stored, otherwise, the same node data are adopted by all editions adopt. With the adoption of the method, the XML database management system (DBMS) can easily obtain all edition numbers of a document, all node data in each edition as well as difference between any two editions; the node data which is repeatedly stored is avoided; and the method is convenient and practical.
