The schema in Datalog consists of two different types of schemas: Extensional Schema:this is the set of extensional relations: an extensional relation occurs only in the right-hand-side of the rules. Such relations are intuitively the "input" of the Datalog program. http://infolab.stanford.edu/~ullman/fcdb/aut07/slides/dlog.pdf release date xbox shenmue 2
