On the Expressiveness of Languages for Querying Property Graphs in Relational Databases
Summary: Formalizes SQL/PGQ as views over relational data and analyzes three fragments—read-only core, read-write with graph creation, and an extended variant with arbitrary-arity identifiers—showing graph creation is the key driver of power. Establishes a strict hierarchy (read-only < read-write < extended), proves read-write is still below NL while the extended fragment exactly captures NL, and shows on ordered structures arity-2 identifiers suffice so the hierarchy collapses, linking the results to classical transitive-closure phenomena.
