In this article, we describe the XML storage system used in the WebContent project. We begin by advocating the use of an XML database in order to store WebContent documents, and w...
Large XML documents which are stored in an XML database can be transformed further by an XSL processor using an XSLT stylesheet. In order to answer an XPath query based on the tran...
Similarity joins in databases can be used for several important tasks such as data cleaning and instance-based data integration. In this paper, we explore ways how to support such ...
While specification languages for integrity constraints for XML data have been considered in the literature, actual technologies and methodologies for checking and maintaining in...
A flexible mandatory access control policy (MAC) for XML databases is presented in this paper. The label type and label access policy can be defined according to the requirements ...
Today, more and more enterprises process XML data, many of them already in XML database systems. Once systems start to grow in size, scalability becomes an issue. One of the core o...
One of the problems associated with XML databases is the poor performance of XPath queries. Although this has attracted much attention by the research community, solutions are eith...
