Generalized Schema-Mappings: From Termination To Tractability
Summary: Generalizes schema-mappings with semantics (Soundness, Completeness, Laconicity) shown equal to cores of universal solutions and extended to nulls/equality. Introduces TOC, an oblivious-chase termination criterion strictly generalizing weak‑acyclicity, gives a new PTIME algorithm, and a decidable PTIME relaxation called Super‑weak Acyclicity.
