Answering Queries Using Views (Extended Abstract)

Summary: Reduces query rewriting to containment mappings from views to the query for conjunctive/union queries with built-in comparisons. Shows NP-completeness, separates complexity into mapping enumeration vs. literal deletion, and gives a poly-time redundancy test that often yields minimal rewritings.
