C++ ASP.NET interface to Amzi! Prolog + Logic Server for building Rule-Based Expert Systems

Sample Image - logo_small.gif

Introduction

The .NET Class encapsulates the Amzi! Logic Server for use by .NET applications and applets. It includes:

A .NET Class Package the encapsulates a Logic Server Engine
Methods that correspond to the Logic Server API Functions
Use of .NET's exception handling for API errors, and
.NET-like method interfaces.

In addition, you can extend the .NET Class to allow Prolog to call methods in your .NET code.

This class is useful for calling Amzi! from .NET applications to implement intelligent logic-bases. It may also be useful to other wrapper developers as it illustrates writing a wrapper class on an existing Windows DLL.

You can download Amzi! Prolog + Logic Server from www.amzi.com/download. The documentation is available at www.amzi.com/manuals/amzi7/amzidoc.htm
