Abstract

XML has become a standard for data exchange in many fields of application. Thus, a huge amount of data in this format is spread around Web and is stored in different ways. In order 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. This paper presents DTX, a mechanism for distributed concurrency control of XML data, based on specific techniques for this kind of data. Aiming to evaluate DTX, experiments were conducted in order to measure its performance.
