....and relations, since this kind of lattices are, by construction, closed with respect to both the union and the intersection operations. 27 Experience Building a Rose Algebra Based Spatial Dood Norman Paton This talk presented experience in the design and implementation of a spatial extension [2] to the ROCK ROLL [1] deductive object oriented database system. The resulting system provides: 1. A rich object data model, with the vector spatial types of the ROSE Algebra [3] supported as spatial literals. 2. A deductive query and rule language for deriving information from the facts ....

....model. The deductive language ROLL and the imperative language ROCK are then derived from this model, and integrated with minimal impedance mismatches. Type inference in ROLL prevents runtime type errors occurring across the language interface, and later work has added active [DPWF96] and spatial [FDPW97] facilities. Validity is the first DOOD to become a product. The system integrates declarative and imperative constructs in the DEL language. Validity is classified as an unilateral language integration approach as there are limitations on the bilateral embedding of the deductive and imperative ....
