This book presents the refereed proceedings of the Second International Workshop on Constraint Database Systems, CDB '97, held in Delphi, Greece, in January 1997 together with some papers presented at the CP '96 Workshop on Constraints and Databases, held in Cambridge, Massachussetts, in August 1996.
The 18 revised full papers presented were carefully reviewed and selected for inclusion in the volume; also included are the extended abstract of an invited contribution and two survey papers. The papers are organized in sections on languages, expressiveness of spatial languages, systems, temporal applications, new applications, indexing, constraint programming, and optimization.
