Safe Locking Policies for Dynamic Databases
Summary: Generalizes Yannakakis' iff characterization of unsafe locking policies—existence of a canonical non-serializable schedule with all but one transaction serial—to dynamic databases that permit entity insertions/deletions. Applies this generalization to prove correctness of three locking policies for dynamic databases. (summarized by gpt-5-mini on Feb 09 2026)
