VisiRule Expert System Demos
Legal Problem Solving, Financial Problem Solving and Machine Diagnostics. As the software has its roots in, and access to, Prolog - the world's foremost logic programming language, there is really no limit as to what can be implemented. In addition, there is a dedicated Business Rules expert systems language, Flex, which enable customized rules to be supplied. This page features various VisiRule expert system demos which show some of the more advanced and versatile aspects of VisiRule such as database access, date capture and manipulation, and HTML integration. There are other demos available which deal with industry specific challenges such as
