The main objective of the ADBIS series of conferences is to provide a forum for the dissemination of research acc- plishments and to promote interaction and collaboration between the database and information systems research communities from Central and East European countries and the rest of the world. The ADBIS conferences provide an inter- tional platform for the presentation of research on database theory, development of advanced DBMS technologies, and their advanced applications. ADBIS 2010 spans a wide area of interests, covering all major aspects related to theory and applications of database technology and information systems. Two di?erent submission lines were considered for ADBIS 2010, one within the classic track and another one within a special track organisation. ADBIS comprised ?ve tracks: 1.
