The series of East European Conferences on Advances in Databases and Information Systems (ADBIS) is an established and prestigious forum for the exchange of the latest research results in data management. It provides unique opportunities for database researchers, practitioners, developers, and users from East European countries to explore new ideas, techniques, and tools, and to exchange experiences with colleagues from the rest of the world. This volume contains the proceedings of the 11th ADBIS Conference, held in Varna, Bulgaria, September 29 - October 3, 2007. The conference included 3 keynote talks, 36 research papers in 13 sessions, and 2 tutorials. Twenty-tree of the research papers as well as papers or extended abstracts for the keynote talks are included here; the remaining papers appear in local proceedings. Distinguished members of the database and information-retrieval communities delivered the three keynotes. Timos Sellis, an expert in the area of multidimensional indexing and data warehousing, analyzed the entire lifecycle of ETL workflows, from specification to optimized execution, offering solutions as well as future challenges. Gerhard Weikum, a leader of several efforts falling at the intersection of databases and information retrieval, discussed the emergence of several "Webs" and how these may be harvested and searched for knowledge. Finally, Paolo Atzeni, well-known for several contributions to database theory, addressed the perennial problem of schema and data translation in the context of emerging model management systems and outlined several research challenges that emerge.
