This book constitutes the thoroughly refereed joint post-proceedings of the VLDB 2002 Workshop on Efficiency and Effectiveness of XML Tools and Techniques, EEXTT and the CAiSE 2002 Workshop on Data Integration over the Web, DIWeb.The 10 revised full papers presented were carefully selected during two rounds of reviewing and revision. The papers are organized in topical sections on XML languages, XML modeling and integration, XML storage, benchmarking XML, and data integration over the Web.

This yearmarks anexciting time in the XML-database space:XQueryis moving closer to becoming a full W3C Recommendation, and the "Big 3" database vendors (IBM, Oracle, Microsoft) are expected to release XQuery support in theirrelationalDBMSs,joininganumberofexistingopensourceandcommercial products. Thus, we are very pleased to feature an industrial paper (describing theXML-speci?cfeaturesofMicrosoftSQLServer)aswellas14researchpapers. XSym's focus this year was on building XML repositories, and papers discussed the following topics: indexing support for the evaluation of XPath and XQuery; benchmarks and algorithms for XQuery and XPath evaluation; algorithms for constraint satisfaction checking, information extraction, and subtree matching; and applications of XML in information systems. This year, XSym also coordinated its e?orts with the Database and P- gramming Languages Symposium, DBPL 2005. The resulting program included not only presentations of the papers in this proceedings, but also a joint DBPL- XSym keynote talk by Giuseppe Castagna, developer of the CDuce language for XML processing, and a joint panel on open XML research problems and challenges.The organizers would like to express their gratitude to the XSym Program Committee and external reviewers for their e?orts in providing very thorough evaluationsofthesubmittedpapersundersigni?canttimeconstraintsandto- crosoftfortheirsponsorshipandfortheuseoftheMicrosoftConferenceMana- ment Toolkit. We would also like to thank Gavin Bierman and Christoph Koch, the organizersof DBPL, for their e?orts andtheir willingness to coordinate with us. These proceedings are dedicated to Alberto Mendelzon who sadly passed awaythisyear.Asastrongsupporterofandactivecontributortothissymposium series he will always remain in our memory.

The annual international conference on Database and Expert Systems Applications (DEXA) is now well established as a reference scientific event. The reader will find in this volume a collection of scientific papers that represent the state of the art of research in the domain of data, information and knowledge management, intelligent systems, and their applications. The 17th instance of the series of DEXA conferences was held at the Andrzej Frycz Modrzewski Cracow College in Kraków, Poland, during September 4–8, 2006. Several collocated conferences and workshops covered specialized and complementary topics to the main conference topic. Four conferences ? the 8th International Conference on Data Warehousing and Knowledge Discovery (DaWaK), the 7th International Conference on Electronic Commerce and Web Technologies (EC-Web), the 5th International Conference on Electronic Government (EGOV), and the Third International Conference on Trust, Privacy, and Security in Digital Business (TrustBus) ? and 14 workshops were collocated with DEXA. The whole forms a unique international event with a balanced depth and breadth of topics. Its much-appreciated conviviality fosters unmatched opportunities to meet, share the latest scientific results and discuss the latest technological advances in the area of information technologies with both young scientists and engineers and senior world-renown experts. This volume contains the papers selected for presentation at the conference. Each submitted paper was reviewed by three or four reviewers, members of the Program Committee or external reviewers appointed by members of the Program Committee.

This two volume set LNCS 7825 and LNCS 7826 constitutes the refereed proceedings of the 18th International Conference on Database Systems for Advanced Applications, DASFAA 2013, held in Wuhan, China, in April 2013.
