Abstract
We propose a Constraint Data Model for spatial applications modelled on a Object-Oriented setting. A first step in this direction was taken by Brodsky and Kornatzky. We augment Brodsky and Kornatzky's model with a few simple primitives, that would make querying the model simpler and more natural. Our basic model is quite similar to the Brodsky and Kornatzky's model but, by the introduction of the notion of a spatial attribute, the modelling of part-subpart relationships is greatly simplified. In fact, we are even able to express “what-if” queries (for example: “Where can I put a desk in the room?”) quite naturally.
