Mechanisms for Concurrency Control in XML
As the people know, eXtensible Markup Language (XML) has become a standard for data exchange in many fields of application. So, a huge amount of data in this format is spread around Web and is stored in different ways. Now, it’s a prime requirement to manage the access of this data, concurrency control techniques have been adopted. Nevertheless, most of these techniques are developed on centralized environments and approaches for distributed environments do not take into account the specificity of XML data. It is developed for database but not for XML data. This paper presents advances in DTX, a mechanism for distributed concurrency control of XML data.
