Extending XQuery with Window Functions

Extending XQuery with Window Functions
This paper presents two extensions for XQuery. The first extension allows the definition and processing of different kinds of windows over an input sequence; i.e., tumbling, sliding, and landmark windows. The second extension extends the XQuery data model (XDM) to support infinite sequences. This extension makes it possible to use XQuery as a language for continuous queries. Both extensions have been integrated into a Java-based open source XQuery engine. This paper gives details of this implementation and presents the results of running the Linear Road benchmark on the extended XQuery engine.
