Conjunctive queries are NP-complete with regard to mixed complexity,[four] whilst the data complexity of conjunctive queries may be very very low, within the parallel complexity class AC0, and that is contained in LOGSPACE and therefore in polynomial time. The NP-hardness of conjunctive queries may well surface stunning, given that relational algebra and SQL strictly subsume the conjunctive queries and are As a result not less than as hard (in actual fact, relational algebra is PSPACE-comprehensive with respect to put together complexity and is particularly hence even more challenging less than broadly held complexity-theoretic assumptions).
