Abstract
An operation for restricting deductive databases represented as logic programs is introduced. The restrictions are represented in a separate deductive database. The operation is given an abstract semantics in terms of the immediate consequence operator. A transformational implementation is given and its correctness is proved with respect to the abstract semantics.File in questo prodotto:
