Query Containment for Data Integration Systems

Summary: Define “relative containment” to capture query containment relative to the sources available to a data integration system (vs. classical containment). Provide tight complexity/decidability bounds for datalog fragments including conjunctive queries, show decidability even with binding-pattern access restrictions, and give tight extensions when comparisons are allowed.
