An expert system is a branch of artificial intelligence. It is used to solve very complex problems by emulating the decision making process of a human being. It utilizes knowledge engineering to encapsulate the rules of operations from human experts, than captures those rules into heuristics and rapidly processes mass amounts of data through the rule set. Forward chaining takes the data through the rule sets marking what conclusions can be drawn, Backward chaining takes the data through the rule set and if conclusions are drawn looks at the marked rules that were not fired to determine if the new conclusions will draw any further conclusions. Hence it is non-linear processing of data in the same manner that human processes information sets.
