The series of International Baltic Biennial Conferences on Databases and Information Systems (Baltic Db&IS) was initiated by Prof. Janis A. Bubenko Jr. (Royal Institute of Technology, Stockholm, Sweden) and Prof. Arne Sølvberg (Norwegian University of Science and Technology, Norway). The first conference was held in 1994 in Trakai, Lithuania. Professors Sølvberg and Bubenko also helped to arrange funding, and even trained researchers from Baltic countries in West European conference organization technologies. This initiative from Janis A. Bubenko Jr. and Arne Sølvberg was indeed a great idea. It helped to consolidate research communities in Baltic countries, to establish contacts with research centres in European countries, both Western and Eastern, and even to renew contacts with researchers in Russia. The Baltic DB&IS conferences now make a major contribution to the development of regional research and boost international cooperation.

The Baltic DB&IS 2012 conference continues this series of successful conferences, held in (Riga 1998, 2004, 2010), Tallinn (1996, 2002, 2008), and Vilnius (2000, 2006). This is the tenth (Jubilee) Conference. The Conference took place on July 8–11 2012, in Vilnius. It was organized by the Lithuanian Academy of Sciences, Vilnius University Institute of Mathematics and Informatics, and the Lithuanian Computer Society and was supported by the Research Council of Lithuania.

The International Programme Committee of the Baltic DB&IS 2012 consisted of 62 members from 23 countries. Sixty nine papers from 14 countries were submitted for conference. As a rule, each paper was reviewed by at least three referees from different countries. As a result of this process, 43 papers were accepted and presented at the conference. Twenty seven of the best-revised papers have been selected for this volume, which also includes two papers presented by invited speakers.

The papers present original results concerning query processing and optimization, data mining, information systems engineering, business process modelling and implementation, service engineering, software evaluation and testing, information systems engineering tools and techniques, e-learning environments, and other related issues.

We would like to express our warmest thanks to all authors who contributed to the 10th Jubilee Baltic DB&IS Conference. Our special thanks to the invited speakers Prof. Janis A. Bubenko Jr., Prof. Marite Kirikova, and Prof. Arne Sølvberg. We are grateful to the members of international Programme Committee and additional referees for their careful reviewing of the submitted papers, and we also take this opportunity to express our very special thanks and deep gratitude to all our sponsors and to the conference organizing team. Last, but not least, we also thank all conference participants.
