Independent Database Schemas (Extended Abstract)

Summary: Complete characterization of schemas that admit no interrelation constraints under the weak-instance semantics (a weakened universal-relation assumption). Focuses on JD+FD constraints and pinpoints exactly when admissible states coincide with a weak instance. (summarized by gpt-5-mini on Feb 09 2026)
