Compression and Query Evaluation over XML Databases
The eXtensible Markup Language (XML) is a World Wide Web Consortium (W3C) recommendation which has widely been used in both commerce and research. In recent years, the authors have witnessed a dramatic increase in the volume of XML digital information that is either created directly as an XML document or converted from another type of data representation. The importance of XML is mainly due to its ability to represent different data types within one document, solving the problem of long-term accessibility, and providing a solution to the problem of interoperability (Al-Hamadani et al., 2009). Extensible Markup Language (XML) W3C Recommendation, October (2000)] is proposed as a standardized data format designed for specifying and exchanging data on the Web.
