Implication is compared with subsumption, the usual test in databases. Subsumption implicates ``implication'', but the converse does not hold. It is shown, however, that if the axiom is not self-resolving and the consequence is not tautological, then implication is equivalent to subsumption. Some consequences and algorithms are also considered.
