Structural Query Optimization — A Uniform Framework For Semantic Query Optimization In Deductive Databases
Summary: Presents factoring and the notion of proof-tree removability: a uniform transformation framework that rewrites Datalog programs to ensure selected recursive subgoals occur only a bounded number of times in proof trees. Generalizes recursively redundant subgoals to produce equivalent programs with smaller, cheaper recursion without solving undecidable boundedness. (summarized by gpt-5-mini on Feb 09 2026)
