—We investigate techniques to automatically decompose any XQuery query—including updating queries specified by the XQuery Update Facility (XQUF)—into subqueries, that can be ...
Though inevitable for effective cost-based query rewriting, the derivation of meaningful cardinality estimates has remained a notoriously hard problem in the context of XQuery. By...

XQuery is a powerful XML query language with many features and syntactic constructs. For many common queries we do not need all the expressive power of XQuery. We investigate the ...

Since the birth of XML, the processing of XML query languages like XQuery/XQueryP has been widely researched in the academic and industrial communities. Most of the approaches con...
The Pathfinder project makes inventive use of relational database technology--originally developed to process data of strictly tabular shape--to construct efficient database-suppo...
A purely relational account of the true XQuery semantics can turn any relational database system into an XQuery processor. Compiling nested expressions of the fully compositional X...
This work may be seen as a further proof of the versatility of the relational database model. Here, we add XQuery to the catalog of languages which RDBMSs are able to "speak&...
XQuery is the emerging standard for querying XML data sources. XLive is a light XML/XQuery mediator developed at University of Versailles whose engine processes an XML algebra der...

Several native approaches to storing large XML data sets exist. In all of these approaches the internal data representation is designed to support any ad-hoc XQuery query. In this...
Order is essential for XML query processing. Efficient XML processing with order consideration over relational storage is non-trivial, especially for complex nested XQuery expressi...
