Data Aggregation, Heterogeneous Data Sources and Streaming Processing: How Can XQuery Help?
Marc Van Cappellen, Wouter Cordewiner, Carlo Innocenti · IEEE Data(base) Engineering Bulletin · 2008
Software infrastructures and applications more and more must deal with data available in a variety of different storage engines, accessible through a multitude of protocols and interfaces; and it is common that the size of the data involved requires streaming-based processing. This article shows how XQuery can leverage the XML Data Model to abstract the data physical details and to offer optimized processing allowing the development of highly scalable and performant data integration solutions.
