The goal of Visual Prolog is to support industrial strength programming of complex knowledge emphasized problems. It supports advanced client-server and three-tier solutions and is especially well suited for dealing with complex knowledge. It is a very powerful and safe programming language combining the very best features of logical, functional and object-oriented programming paradigms in a consistent and elegant way.
Visual Prolog features:
* Logical programming concepts (backtracking, pattern matching)
* Algebraic data types
