Processing Queries on Tree-Structured Data Efficiently

Summary: Survey of algorithms, complexity results, and techniques for efficient evaluation of node/tuple queries on trees (conjunctive queries, FO, Datalog, XPath). Organizes results by the core ideas yielding tractability and exposes previously unnoticed connections among approaches. (summarized by gpt-5-mini on Feb 09 2026)
