A Theory of Regular Queries
Summary: Introduces RQ (regular queries), a natural, operation-closed class for graph/relational queries supporting disjunction, conjunction, projection and transitive closure while retaining decidable query-containment. Shows RQ = a Datalog fragment where recursion is restricted to transitive closure, yielding an expressive yet containment-decidable fragment that enables decidable query optimization.
