On the Decidability and Finite Controllability of Query Processing in Databases with Incomplete Information

Summary: Characterizes decidability/undecidability and the finite-controllability frontier for OWA query answering with functional (keys) and inclusion dependencies across CQs/UCQs (±negation, inequality), comparing finite vs unrestricted DB semantics. Derives consequences for IC implication and query containment, notably proving finite controllability of CQ containment under arbitrary inclusion dependencies and under key/foreign-key dependencies, resolving two long-standing open problems.
