… There are more spots than immediately obvious in XQuery expressions where order … but the prevalent impact of order on the XQuery semantics reaches deep into any compliant XQuery processor, making it non-trivial to set this potential free. Here, we …
icde 2007: 226-235 [doi]… 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 …
VLDB 2004: 252-263 [doi]… XML Schema awareness has been an integral part of the XQuery language since its … that backs up XQuery type expressions, such as typeswitch, instance … XQuery applications, where data come with detailed type information from an XML …
edbt 2008: 38-48 [doi]… efficient database-supported XML and XQuery processors. Pathfinder targets database … traditional database systems make for suitable XQuery runtime environments … has been developed with a close eye on the XQuery semantics, some …
DEBU, 31(4):7-14, 2008. [doi]… We introduce a controlled form of recursion in XQuery, an inflationary fixed … the optimization of general user-defined recursive functions in XQuery appears elusive, we … that the recursive XQuery expressions are distributive. We test distributivity …
icde 2008: 1504-1506 [doi]… for the new language.
This demonstration features our XQuery compiler Pathfinder, the continuation of our earlier work on a purely relational XPath and XQuery … a full-fledged XQuery implementation. The demonstration will show …
VLDB 2005: 1322-1325 [doi]… 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 XQuery language, however, yields odd algebraic plan …
edbt 2010: 147-158 [doi]… in the context of XQuery. By basing the estimation on a relational representation of the XQuery syntax, we show how existing cardinality estimation techniques for XPath … dependable forecasts for arbitrary XQuery (sub)expressions. Our approach benefits from …
pvldb, 1(1):463-477, 2008. [doi]… We introduce a controlled form of recursion in XQuery, an inflationary fixed … of general user-defined recursive functions in XQuery appears elusive, we describe how … that the recursive XQuery expressions are distributive. We test distributivity syntactically …
