FluXQuery: An Optimizing XQuery Processor for Streaming XML Data Christof Koch, Stefanie Scherzinger, Nicole Schweikardt, and Bernhard Stegmaier   View Paper (PDF)   Return to DEMO GROUP 3: XML Abstract We present the FluXQuery engine, the first optimizing XQuery engine for XML streams. Optimization in FluXQuery is based on a new internal query language called FluX which slightly extends XQuery by a construct for event-based query processing. By allowing for the conscious use of main memory buffers, it supports reasoning over the employment of buffers during query optimization and evaluation. ©2005 Association for Computing Machinery
