We will introduce the basic ideas involved by working through a simple example. Disadvantages : The database is assumed to represent what is true about a particular problem domain. Do you know? My idea is to try to rebuild something similar and skipping the parser part completely If you can prove it, go on to prove B and ignore C. If A fails, however, go on to prove C ignoring B. This will introduce us to the three basic constructs in Prolog: facts, rules, and queries. That is, we are now able to learn about proof search.

Now that we know about matching, we are in a position to learn how Prolog actually searches a knowledge base to see if a query is satisfied. Every fact/rule ends with a dot (.). Unification : The basic idea is, can the given terms be made to represent the same structure. For this reason it is a frequently used language in Artificial Intelligence where manipulation of symbols and inference about them is a common task.
