Path Query Processing in Large-Scale XML Databases

Query Processing for Large-Scale XML Message Brokering

Query Processing of Integrated XML Databases

Query processing of integrated XML databases has recently received considerable attention. It helps users to extract information from an integrated XML databases system. A flexible and efficient framework for such query processing is proposed. Through a single request, without concern about their internal structures and geographical distribution, it allows decomposition of global queries into s...

Path Sequence-Based XML Query Processing

We present the path sequence storage model, a new logical model for storing XML documents. This model partitions XML data and content according to the document paths; and uses ordered sequences as logical and physical structures. Besides being very compact, this model has a strong impact on the efficiency of XQuery evaluation. Its main advantages are: fast and selective data access plans; intel...

Efficient Path Query Processing on Encoded XML

As XML has become a popular format for information exchange, the efficient processing of broadcast XML data on a constrained device (for example, a cell phone or a PDA) becomes a critical task. In this paper we present the EXPedite system: a new model of data processing, which “migrates” the power of the data-sending server to receivers for efficient processing. It consists of a general encodin...

Query Processing and Optimization in Native XML Databases

XML has emerged as a semantic markup language for documents as well as the de facto language for data exchange over the World Wide Web. Declarative query languages, such as XPath and XQuery, are proposed for querying over large volumes of XML data. A number of techniques have been proposed to evaluate XML queries more efficiently. Many of these techniques assume a tree model of XML documents an...
