This volume continues the series of proceedings of the annual ADBIS conferences
in the field of advances in databases and information systems.
ADBIS, founded by the Moscow ACM SIGMOD Chapter, was extended into
a regular East-European conference in 1996 to establish a forum for promoting
interaction and collaboration between the database research communities
of Eastern and Central Europe and the rest of the world, and thus the ADBIS
conferences provide an international platform for the presentation of research
on database theory, development of advanced DBMS technologies, and their
The fact that this year eight of the countries that have representatives in the
ADBIS Steering Committee became member countries of the European Union
gives a new perspective on the role and mission of the ADBIS community.
Following Dresden (Germany, 2003), Bratislava (Slovakia, 2002), Vilnius (Lithuania,
2001), Prague (Czech Republic, as a joint ADBIS-DASFAA conference
in 2000), Maribor (Slovenia, 1999), Poznan (Poland, 1998), and the starting
place St. Petersburg (Russia, 1997), and preceding Tallin (Estonia, 2005), the
next venue, the “tour of Eastern and Central Europe” of ADBIS conferences
arrived at Budapest (Hungary, 2004).
The series of East-European Conferences on Advances in Databases and Information
Systems continues, with a growing interest that is demonstrated in
the number of submitted contributions. This year the international Program
Committee had an intensive load in evaluating the 130 submitted papers.
As a tradition since 1998, the best 25–30 contributions were selected to be
published in the Springer LNCS series. This year’s volume contains 27 submitted
papers and one invited paper.
In response to the high activity in paper submission and to fulfil the main
objective of the ADBIS conferences, the organizers decided to give more room
for presentation, and accepted from the PC ranking the next 25 papers for
presentation. Thanks to the support from one of the organizing institutions,
the Computer and Automation Research Institute of the Hungarian Academy
of Sciences, these contributions will also be published, in a local volume of the
proceedings in the series of publications of CARI.
Many individuals and institutions supported the organization of this conference
and made this year’s publication possible. Our special thanks go first to
the authors and invited speaker for their outstanding and strenuous work and
contributions. Also, the work of the Program Committee members who accepted
the unexpectedly heavy load in reviewing a large number of contributions
so that we were able to meet the deadline is gratefully acknowledged.
We received important financial support for the publication of the proceedings
from the Faculty of Informatics of the Eötvös Loránd University.
