The ?rst overseas Symposium at the purposes of Constraint Databases (CDB2004) happened in Paris, France, on June 12–13, 2004, earlier than the ACM SIGMOD and PODS meetings. because the ebook of the paper “Constraint question Languages” by way of Kan- lakis, Kuper and Revesz in 1990, the decade has visible a turning out to be curiosity in constraint database conception, question overview, and purposes, re?ected in various meetings, journals, and books. Constraint databases have confirmed to be super ?exible and adoptable in environments that relational database structures can't serve good, akin to geographic details platforms and bioinf- matics. This symposium introduced jointly humans from numerous different parts all c- tributing to the perform and the applying of constraint databases. It was once a continuation and extension of earlier workshops held in Friedrichshafen, G- many (1995), Cambridge, united states (1996), Delphi, Greece (1997), and Seattle, united states (1998) in addition to of the paintings within the finished quantity “Constraint information- ses” edited via G. Kuper, L. Libkin and J. Paredaens (2000) and the textbook “Introduction to Constraint Databases” via P. Revesz (2002). the purpose of the symposium was once to open new and destiny instructions in c- straint database examine; to deal with constraints over domain names except the reals; to give a contribution to a greater implementation of constraint database structures, specifically of question review; to deal with e?cient quanti?er removal; and to explain functions of constraint databases.
