 Database Handling (Internal)

Because Prolog represents a relational database as a collection of facts, you can use it as a powerful query language for internal databases. Visual Prolog's unification algorithm automatically selects facts with the correct values for the known arguments and assigns values to any unknown arguments, while its backtracking algorithm can give all the solutions to a given query.

prolog_compile_module
