Abstract

Concurrent accessing of XML data becomes more and more important for XML-based applications, especially for Native XML Database systems (NXD) because of the dramatic growth of number and complexity of such applications. Transaction is a potential solution for the concurent accessing of XML data. However, research on transaction of NXD is still very limited. This paper proposes a transaction model for NXD management systems. It introduces a NXD storage model which is suitable for accessing XML data using XPath and XQuery. A locking protocol, Schema path Lock Protocol, is designed for this transaction model. An implementation of such transaction model is presented last in this paper.
