SEBD 2010 Proceedings of the 18th Italian Symposium on Advanced Database Systems

PrefaceThis volume collects the papers selected for presentation at the Eighteenth ItalianSymposium on Advanced Database Systems (SEBD 2010), held in Rimini,Italy, from the 20th to the 23rd of June 2010.SEBD is the major annual event of the Italian database research community.The symposium is conceived as a gathering forum for the discussionand exchange of ideas and experiences among researchers and experts fromthe academy and industry, about all aspects of database systems and their applications.SEBD is back in Rimini after sixteen years, and it is interesting to observehow the landscape of the Italian database research community has changed. In1994 twenty-one papers were accepted, now the number has more than doubled,meaning that the community has been steadily growing. Most of the topicsconsidered in 1994 are still around, even if the language, the formalisms andthe reference applications have changed. The Web was e-mail, FTP, Usenet,a small amount of HTML pages here and there, and little more, now it isthe pervasive engine of information dissemination and search. The Web is sopowerful that a series of brand new ideas and applications have arisen fromit, due to a mix of possibility and necessity. Social systems across the Web,mobility, and heterogeneity were not conceivable in the early 1990s. Semanticweb, data mining and warehousing, streaming techniques, large scale integrationare necessary to deal with the growing amount of data and information.The SEBD 2010 program reects the current interests of the Italian databaseresearchers and covers most of the topics considered by the international researchcommunity. Sixty papers were submitted to SEBD 2010, of which twenty-twowere research papers, two were software demonstrations, and thirty-four wereextended abstracts, i.e., papers containing descriptions of on-going projects orpresenting results already published. Fifty-one papers were accepted for presentation,of which seventeen were research papers, two were software demonstrations,and thirty-two were extended abstracts.Besides paper presentations, the program includes a tutorial by Divesh Srivastava(AT&T Labs-Research) and two invited talks, the rst by Hector Garcia-Molina (Stanford University, CA) and the second by Amr El Abbadi (Universityof California, CA).We would like to thank all the authors who submitted papers and all symposiumparticipants. We are grateful to the members of the Program Committeeand the external referees for their thorough work in reviewing submissions withexpertise and patience, and to the members of the SEBD Steering Committeefor their support in the organization of SEBD 2010.
