Linear Approximation of Semi-algebraic Spatial Databases Using Transitive Closure Logic, in Arbitrarebraic spatial databases in arbitrary dimensions, our earlier results being true for only two dimensions..Consequently, we can prove that first-order logic with a transitive closure operator extended with stop conditions, can express all Boolean topological queries on semi-algebraic spatial databases of arbitrary dimension.

Molecular Interrelationships and Functions,ne nature of time..We investigate different genericity classes relative to the constraint database model for spatio-temporal databases and we identify sound and complete languages for the first-order, respectively the computable, queries in these genericity classes.
