Spatio-temporal data handling with constraints

Abstract

llo~t spatial information systems are limited to a fixed dirnemion (generally 2) which is not extensible-On the other hand, the emer@g paradigm of con~traint dat abaws allows the representation of data of arbk-ary dimensio~together with abstract query Ianaqages The complexity of evaluating querias though might be costly if the dima~ion of the objects is really arbitrary.
