The main objective of the ADBIS series of conferences is to provide a highly visible forum for the dissemination of research accomplishments and to promote interactions and collaborations among the database and information systems research communities from Central and Eastern European countries and with the rest of the world. The ADBIS conferences provide an international platform for the presentation of research on database theory, information systems, advanced DBMS technologies, and their advanced applications.
ADBIS 2011 was the 15th instantiation of this series. It took place in Vienna, Austria, September 20–23, 2011, organized by the Institute of Software Technology and Interactive Systems of the Vienna University of Technology. ADBIS 2011 continued the ADBIS series held in St. Petersburg (1997), Poznan (1998),Maribor (1999), Prague (2000), Vilnius (2001), Bratislava (2002), Dresden (2003), Budapest (2004), Tallinn (2005), Thessaloniki (2006), Varna (2007), Pori (2008), Riga (2009), and Novi Sad (2010).
This volume contains 30 contributed research papers selected from 105 submissions from 31 countries. The thorough reviewing process – each paper was reviewed by three to five Program Committee members – was highly competitive as the acceptance rate of 29% indicates. In addition to the contributed papers, these proceedings contain two papers documenting invited keynote talks. Furthermore, 22 papers were accepted as short papers. These are included in the additional proceedings “ADBIS 2011 Research Communications” published by the Austrian Computer Society and in the CEUR workshop proceedings (www.ceur.org). These proceedings also contain the papers accepted for the Doctoral Consortium.
This is the place to express our gratitude to all those who made ADBIS 2011 possible by generously and voluntarily sharing their knowledge, skills and time: the local Organization Chair Amirreza “Nick” Tahamtan for providing an excellent environment for the conference, the Austrian Computer Society for their help in all organizationalmatters, and all other colleagues holding offices. In particular, we thank the Program Committee members as well as the additional reviewers for devoting their expertise and time to ensure the high quality of the conference in an extensive review and discussion process. And last but not least, we are grateful to all the authors who showed their appreciation of the conference by submitting their valuable work.
