ICDT is a scientific conference on research on the foundations of database systems. Having a European identity, it is typically held in historical European locations; ICDT can be seen as the European version of PODS (the ACM Symposium on Principles of Database Systems). Previous ICDT events were held in Rome, Bruges, Paris, Berlin, Prague, Delphi, Jerusalem, London, Siena, Edinburgh, Barcelona, St Petersburg, Lausanne, Uppsala, Berlin, Genoa, Athens, Brussels, Bordeaux, Venice and Vienna. Since 2009, ICDT is held annually and jointly with EDBT, following the successful SIGMOD/PODS model.
