Semantics de?nes a notion of a lay of a DP (i.e. a possible state of the worldly concern congenial with the DP statements) and characterizes the collection of valid consequences of a program. different tasks ar reduced to ?nding models or computing consequences of a DP. Models ato mic mo 18 found and/or consequences are computed by everyday innovation reasoning algorithms often called inference engines.

Elements of O, F, P are called object, spot, and say images (or constants) respectively.

Predicate constants are used to distinguish relations in the midst of the theatre of operationss objects, Each function and predicate symbol is associated with its arity - an integer indicating the number of symbols parameters. Normally, arity will be determined from the context. Elements of V are cal led (object) variables.

If t1, . . . , tn are terms and f ? F then f (t1, . . . , tn) is a term. damage not containing variables are called ground. They are used to name the domains objects.
