The ADBIS series of conferences aims at providing a forum for the dissemination of research accomplishments and at promoting interaction and collaboration between the database and information systems research communities from European countries and therestoftheworld.TheADBISconferencesprovideaninternationalplatformforthe presentation of research on database theory, development of advanced DBMS tech- nologies, and their advanced applications. As such, ADBIS has created a tradition: its 21st anniversary edition in 2017 continued the 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), Novi Sad (2010), Vienna (2011), Poznan (2012), Genoa (2013),Ohrid(2014),Poitiers(2015),andPrague(2016).Theconferencesareinitiated and supervised by an international Steering Committee consisting of representatives from Armenia, Austria, Bulgaria, the Czech Republic, Cyprus, Estonia, Finland, France, Germany, Greece, Hungary, Israel, Italy, Latvia, Lithuania, the FYR of Macedonia, Poland, Russia, Serbia, Slovakia, Slovenia, and the Ukraine. The program of ADBIS 2017 included keynotes, research papers, thematic work- shops,andadoctoralconsortium.Theconferenceattracted107papersubmissionsfrom 38 countries from many continents. After rigorous reviewing by the Program Com- mittee (88reviewersfrom33countriesintheProgram Committee andadditionally by 26externalreviewers),the26papersincludedinthisLNCSproceedingsvolumewere accepted as full contributions, making an acceptance rate of 24%.
