The efficient management of geometric data, such as points, curves, or polyhedra in arbitrary dimensions, is of great importance in many complex database applications like CAD/CAM, robotics, or computer vision. To provide optimal support for geometric operations, it is crucial to choose efficient data representation schemes. The first part of this book contains a taxonomy and critical survey of common operations and representation schemes for geometric data. Then several new schemes for the efficient support of set operations (union, intersection) and search operations (point location, range...

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,...
