Logic Programming is a style of programming in which programs take the form of sets of sentences in the language of Symbolic Logic. and we define classical logic programs as sets of view definitions, written using traditional Prolog-like notation but with semantics given in terms of datasets rather than implementation.

Relational databases have quickly come to be regarded as a natural and efficient way of organizing information. Duplicate data can be eliminated and powerful set-theoretic operations can be used to manipulate data. But finding the right relations for a database is not yet a trivial step for the uninitiated. This book presents a comprehensive logic programming implementation of the relational design methodology. It employs TURBO Prolog to test and establish computational viability of the relevant algorithms. It also presents the expert system prototype of a user interface, designed especially for builders of computerized databases who may have no formal training in database design.
