The Herbrand model of a Datalog application would be the smallest subset on the Herbrand foundation this sort of that, for each floor occasion of each and every rule in This system, more info if the atoms in the body in the rule are from the established, then so is the head.[five] The product-theoretic semantics outline the minimal Herbrand design to generally be the which means of the program.
