This material is then organized in a format suitable for representation in a computer and a set of tools for inquiry, manipulation, and response is applied. While such systems do not often replace the human experts, they can serve as useful adjuncts or assistants. Expert systems imitate human experts in many different fields of expertise. Such systems contain rules (such as decision tables) that help human answer expert questions.
Advantages of Expert Systems * The computer can store far more information than a human. * The computer does not 'forget', make silly mistakes or get drunk when it is most needed. * Data can be kept up-to-date. * The expert system is always available 24 hours a day and will never 'retire'. * The system can be used at a distance over a network.
