Linear Approximation of Planar Spatial Databases Using Transitive-Closure Logic
We consider spatial databases in the plane that can be defined by polynomial constraint formulas. Motivated by applications in geographic information systems, we investigate line...

On Topological Elementary Equivalence of Spatial Databases
We consider spatial databases and queries definable using first-order logic and real polynomial inequalities. We are interested in topological queries: queries whose result only ...
