Conjunctive queries are NP-comprehensive with regard to combined complexity,[4] when the data complexity of conjunctive queries is very small, within the parallel complexity course AC0, that is contained in LOGSPACE and therefore in polynomial time. The NP-hardness of conjunctive queries may seem astonishing, since relational algebra and SQL strictly subsume the conjunctive queries and so are thus at least as really hard (in reality, relational algebra is PSPACE-total with regard to put together complexity and it is therefore even more challenging underneath widely held complexity-theoretic assumptions).
