Prolog is a logic based programming language, and was developed in the early 1970s and is a practical programming language particularly useful for knowledge representation and artificial intelligence (AI) applications. Prolog is different from many common computer languages in that it is not a procedural language (such as Basic, C, or Java). It is an interpreted logic based declarative language and as such has no loops, jumps, type declarations or arrays, and no fixed control constructs. In the past this has led to the impression that Prolog is a restricted language, useful only for highly specialized programming tasks by enthusiasts (Callear, 1994; Krzysztof, 1997). However, this is not the case and modern versions of Prolog are well equipped and versatile, and can be used for any programming task. The latest generations of the language (e.g., Visual Prolog) can also be integrated into more common object oriented languages.
