This volume contains the best papers presented at the 7th International Baltic Conference on Databases and Information Systems (BalticDB&IS’2006). The series of Baltic DB&IS conferences has been initiated by Janis Bubenko jr. and Arne Solvberg in 1994. The conferences are highly international and bring together academics and practitioners from the entire world. They are organized by the Baltic countries in turn. The first conference was held in Trakai (1994), then followed conferences in Tallinn (1996), Riga (1998), Vilnius (2000), Tallinn (2002), Riga (2004), and again in Vilnius. The conference BalticDB&IS’2006 took place on July 3–6, 2006. It was organized by the Department of Information Systems (Vilnius Gediminas Technical University) and Software Engineering Department (Institute of Mathematics and Informatics). The conference has been approved by the IEEE Communication Society for Technical Cosponsorship.
The call for papers attracted 84 submissions from 21 countries. In a rigorous reviewing process the international program committee selected 48 papers for the presentation at the Conference and 27 for publishing in the Proceedings published by IEEE. After the Conference the program committee selected 20 best papers to be published in this volume. All these papers have been extended significantly and rewritten completely. They have been reviewed by at least 3 reviewers from different countries who evaluated their originality, significance, relevance, and presentation and found their quality suitable for the publication in this volume. These papers present original results in business modeling and enterprise engineering, database research, data engineering, data quality and data analysis, IS engineering, Web engineering, and application of AI methods. We hope that the presented results will contribute to the further development of research in DB and IS field.
