    - Expert systems are special databases which are designed to mimic (copy) the expertise and knowledge of a human expert in various different subjects.
    - Knowledge from human experts is entered into the system and stored.
    - People using the expert system can then question it (query) and access this stored knowledge. The system searches it's stored data for anything that provides an answer to the information that a user has input.
    (The expert system can provide the answers to difficult problems in the same way that human experts could!!
    Expert systems can be used for a wide range of purposes. Here are a few of them:
    1 Medical Diagnosis
    Expert systems in doctors surgeries and hospitals
    - Expert systems are used in doctors surgeries and hospitals to help medical professionals diagnose patients correctly.
    - These expert systems make it easy for doctors to match symptoms to probable causes. they also recommend what action the doctor should take (e.g. correct medication)
    2 Expert systems within self-diagnosis web sites
    -Some health services have web sites that allow users to self-diagnose themselves. 
    - The expert system guides the user through a set of questions which are answered by typing in boxes or clicking options. 
    -The system will suggest a diagnosis and the user can decide if it is serious enough to call a doctor or if the health problem can be solved with a an asprin and rest.
    - medical diagnosis expert systems can help doctors to figure out what is wrong with patients. they also suggest possible treatments

    Firstly, experts in the field are interviewed, and the data derived from them is collected. A knowledge base is then designed and created, here the knowledge from experts is stored here. The rules base is then designed and created and an interface engine is also implemented. An explanation system is also developed. The user interface is created. Lastly, the expert system is tested against scenarios.

    Advantages
    Provide consistent answers and are unfazed by emotional reasoning.
    They are unforgetful, time saving and give accurate results.
    Allow access to wide areas of expertise
    Labor saving

    Disadvantages
    If one component stops working, the other components will also halt, giving inaccurate, bogus results.
    Lack of common sense
    Errors in knowledge base can lead to incorrect decisions being made
    Expensive to set u    p
