An analysis of XQuery benchmarks

Loredana Afanasiev, Maarten Marx
2008 Information Systems  
Our conclusions are based on an usage analysis, on an in-depth analysis of the benchmark queries, and on experiments run on four XQuery engines: Galax, SaxonB, Qizx/Open, and MonetDB/XQuery.  ...  This paper presents a survey and an analysis of the XQuery benchmark publicly available in 2006 -XMach-1, XMark, X007, the Michigan benchmark, and XBench -from different perspectives.  ...  Section 6 contains an analysis of the errors we found in the benchmark queries and a sample of comparison results.  ...

Analyzing Plan Diagrams of XQuery Optimizers [chapter]

H. S. Bruhathi, Jayant R. Haritsa
2012 Lecture Notes in Computer Science  
Through a comprehensive set of experiments on a variety of popular benchmarks, we demonstrate that XQuery plan diagrams can be significantly more dense and complex as compared to their relational counterparts  ...  In this paper, we analyze the behavior of industrial-strength XQuery optimizers using the notion of "plan diagrams", which had hitherto been applied solely to relational engines.  ...  Subsequently, using the developed framework, we carry out a detailed analysis of a popular commercial hybrid XQuery/SQL optimizer, which we refer to as XOpt, through an extensive set of plan diagrams generated  ...

Projecting XML Documents [chapter]

Amélie Marian, Jérôme Siméon
2003 Proceedings 2003 VLDB Conference  
The main contribution of the paper is a static analysis technique that can identify at compile time which parts of the input document are needed to answer an arbitrary XQuery.  ...  These applications suffer from the limitations of current main-memory XQuery processors which break for rather small documents.  ...  We want to thank Sihem Amer-Yahia, Irini Fundulaki, and the Database Group at Columbia University for their feedback on earlier versions of the paper.  ...

Mapping between RDF and XML with XSPARQL

Stefan Bischof, Stefan Decker, Thomas Krennwallner, Nuno Lopes, Axel Polleres
2012 Journal on Data Semantics  
We focus on the semantics of this combined language and present an implementation, including discussion of query optimisations along with benchmark evaluation.  ...  The Extensible Markup Language (XML) has become widely adopted as an almost ubiquitous interchange format for data, along with transformation languages like XSLT and XQuery to translate data from one XML  ...  The architecture of our implementation is shown in Fig. 14 and consists of three main components:(1) a query rewriter, which turns an XSPARQL query into an XQuery; (2) an XQuery engine for evaluating  ...

Albrecht Schmidt, Florian Waas, Martin Kersten, Daniela Florescu, Michael J. Carey, Ioana Manolescu, Ralph Busse
2001 SIGMOD record  
In this paper, we outline desiderata for a benchmark for XML databases drawing from our own experience of developing an XML repository, involvement in the definition of the standard query language, and  ...  Benchmarks belong to the very standard repertory of tools deployed in database development.  ...  The authors would like to thank Stefan Manegold and Niels Nes for their comments on an early draft of this paper. The first author would also like to thank Michael Rys for his valuable input.  ...

A Prototype for Translating XQuery Expressions into XSLT Stylesheets [chapter]

Niklas Klein, Sven Groppe, Stefan Böttcher, Le Gruenwald
2005 Lecture Notes in Computer Science  
Instead of implementing XQuery support for every tool, we propose to use an XQuery to XSLT translator.  ...  The W3C developed XQuery for the purpose of querying XML data, but XQuery is not available in every tool. Because of historical reasons, many tools only support processing XSLT stylesheets.  ...  Experimental Environment We have used the XMark benchmark [10] for all our experiments. This benchmark consists of 20 XQuery queries and an XML data generator.  ...

XPathMark: An XPath Benchmark for the XMark Generated Data [chapter]

Massimo Franceschet
2005 Lecture Notes in Computer Science  
We propose XPathMark, an XPath benchmark on top of the XMark generated data. It consists of a set of queries which covers the main aspects of the language XPath 1.0.  ...  We suggest a methodology to evaluate the XPathMark on a given XML engine and, by way of example, we evaluate two popular XML engines using the proposed benchmark.  ...  From this analysis, we conclude that, under our testing environment, Saxon is well performing up to a break point corresponding to an XML documents of size 29.9 MB, while the break point for Galax corresponds  ...
