Making Object-Oriented Schemas More Expressive
Summary: Introduces CAR, an OO data model adding attribute inverses, class union/intersection/complement, non‑binary relations, and cardinality constraints to express richer schema knowledge. Provides consistency/inference algorithms and analyzes their computational complexity. (summarized by gpt-5-mini on Feb 09 2026)
