th This volume contains papers presented during 13 International Conference on Inf- mation Systems Development - Advances in Theory, Practice and Education (ISD'2004), held in Vilnius, Lithuania, September 9-11, 2004. The intended audience for this book comprises researchers and practitioners interested in current trends in the InformationS- tems Development (ISD) ?eld. Papers cover a wide range of topics: ISD methodologies, methodengineering,businessandISmodelling,websystemsengineering,databaserelated issues, informationanalysisanddatamining,qualityassessment, costingmethods,security issues, impact of organizational environment, and motivation and job satisfaction among IS developers. The selection of papers was carried out by the International Program C- mittee. All papers were reviewed in advance by three reviewers and evaluated according to their relevance, originality and presentation quality. Papers were evaluated only on their own merits, independent of other submissions. Out of 117 submissions Program Comm- tee selected 75 research papers to be presented at the Conference. 39 best papers and 5 papers presented by invited speakers are published in this volume. th The13 InternationalConferenceonInformationSystemsDevelopmentcontinuesthe tradition started with the ? rst Polish-Scandinavian Seminar on Current Trends in Infor- tion Systems Development Methodologies, held in Gdansk, Poland in 1988. Through the years this seminar has evolved into one of most prestigious conferences in the ?eld. ISD Conferenceprovidesan internationalforumfor the exchangeof ideasbetween the research community and practitioners and offers a venue where ISD related educational issues are discussed. ISD progresses rapidly, continually creating new challenges for the professionals - volved. New concepts and approaches emerge in research as well as in practice.

Modern information systems differ in essence from their predecessors. They support operations at multiple locations and different time zones, are distributed and network-based, and use multidimensional data analysis, data warehousing, knowledge discovery, knowledge management, mobile computing, and other modern information processing methods. This book considers fundamental issues of modern information systems. It discusses query processing, data quality, data mining, knowledge management, mobile computing, software engineering for information systems construction, and other topics. The book presents research results that are not available elsewhere. With more than 40 contributors, it is a solid source of information about the state of the art in the field of databases and information systems. It is intended for researchers, advanced students, and practitioners who are concerned with the development of advanced information systems.

This volume contains the best papers presented at the 12th East-European Conference on Advances in Databases and Information Systems (ADBIS 2008) held during S- tember 5-9, 2008, in Pori, Finland. The series of ADBIS conferences is the successor of the annual international workshops with the same title that during 1993-1996 were organized in Russia by the Moscow ACM SIGMOD Chapter. ADBIS 2008 continues the series of ADBIS conferences held in St. Petersburg, Russia (1997), Poznan, Poland (1998), Maribor, Slovenia (1999), Prague, Czech Republic (2000), Vilnius, Lithuania (2001), Bratislava, Slovakia (2002), Dresden, Germany (2003), Budapest, Hungary (2004), Tallinn, Estonia (2005), Thessaloniki, Greece (2006), and Varna, Bulgaria (2007). The conferences are initiated and supervised by an international Steering Committee chaired by professor Leonid Kalinichenko. The ADBIS conferences established an outstanding reputation as a scientific event of high quality serving as an internationally highly visible showcase for research achie- ments in the field of databases and information systems. ADBIS 2008 aimed to create conditions for experienced researchers to impart their knowledge and experience to the young researchers at pre- or post-doctoral level, and to promote interaction and colla- ration between European research communities (especially from Central and East Europe) and the rest of the world. The conference encourages contacts between the p- ticipants who are nationals of, but active outside, the Member States and Associated States and their colleagues in Member States and Associated States. Special attention is paid to collaboration of researchers in Central and East Europe.

This book constitutes the refereed proceedings of the 5th East European Conference on Advances in Databases and Information Systems, ADBIS 2001, held in Vilnius, Lithuania, in September 2001.
The 25 revised full papers presented together with one invited paper and two abstracts of invited talks were carefully reviewed and selected from 82 submissions. The papers are organized in topical sections on query optimization, multimedia and multilingual information systems, spatiotemporal aspects of databases, data mining, transaction processing, conceptual modeling and information systems specification, active databases, query methods, XML, and information systems design.
