This paper extends this relational XML processing stack and shows that an RDBMS can also serve as a highly efficient XQuery runtime environment. Our approach is purely relational: XQuery expressions are compiled into SQL code which operates on the tree encoding. The core of the compilation procedure trades XQuery's notions of variable scopes and nested iteration (FLWOR blocks) for equi-joins. The resulting relational XQuery processor closely adheres to the language semantics, e.g., it obeys node identity as well as document and sequence order, and can support XQuery's full axis feature. The system exhibits quite promising performance figures in experiments. Somewhat unexpectedly, we will also see that the XQuery compiler can make good use of SQL's OLAP functionality.</dcterms:abstract> <dcterms:title>XQuery on SQL Hosts</dcterms:title> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/6260"/> <dc:creator>Grust, Torsten</dc:creator> </rdf:Description> </rdf:RDF>
