PROLOG IS AN INTERPRETED LANGUAGE , NOT A COMPILED ONE .IT MEANS THAT INSPITE OF COMPILING AND GETTING THE CODE TO A LOWER LEVEL , MACHINE IS BROUGHT A LEVEL UP .

IT IS EXTREMELY SUITABLE FOR APPLICATIONS LIKE PATTERN MATCHING , ARTIFICIAL INTELLIGENCE ETC . USING PROLOG , WE CAN ACHIEVE MANY THINGS , WHICH WILL BE DIFFICULT TO ACHIEVE USING A COMPILED LANGUAGE .

PROLOG IS DIFFERENT FROM OTHER LANGUAGES , PRIMARILY BECAUSE OF A FEATURE CALLED BACKTRACKING ,WHERE THE SYSTEM ITSELF WORKS OUT ALTERNATE SOLUTIONS TO A QUERY.

THE PROCEDURAL OR OBJECT ORIENTED WAY OF THINKING CAN REALLY BE A HAMPERING TO PROGRAMMING IN PROLOG . IN PROLOG , EVERYTHING THING IS REPRESENTED USING PREDICATES . U SHOULD THINK IN A PREDICATE BASED WAY TO SOLVE THE PROBLEM
