Concurrency Control Access of Dynamic XML Document with the Locking Method

Abstract

XML is a popular media in many commercial transactions. It is necessary to support XML document access by multiple users concurrently. The access method of single-user for XML document is unsuitable in a multi-user environment. In this paper, we propose three concurrency control algorithms for searching, inserting, and modifying relative element data in a dynamic XML document. With the locking techniques, the algorithms allow multiple users to concurrently access the same data without any error occurrence.
