    We can probably help you, but in order to do that we need to see the problem specification and the ERD that you have produced from that specification.

    In theory, theory and practice are identical. In practice, theory and practice are unrelated.

    so what do you think needs refining
    where do you believe your model is failing to meet the business needs
    where, if any, do you think there are flaws in the model
    can the model support the business assignment, sorry requirements

    have you worked through your ERD to see if the actual data can work in your proposed schema

    erm its your erd, its your assignment
    you must have a clear idea of what business rules you are trying to develop this model for.
    without knowing what it should represent how can you, or anybody for that matter know if this is a good / bad / indifferent representation of what is required?

    as its an erd I guess most contributors here are expecting you to do the erd and pose question about things you are not certain about. but I doubt very mugvh they will 'overview' an erd to see if its 'right'

    define
    get an idea to let it more advance?
    ..how would you judge if the current design is good / bad / indifferent
    waht else do you think you may need to incorporate to 'advance' this design.
    what is making you do this erd. whatever that is should give you a good indication of you need to accomplish.

    there are quite a few templates / pre existing erd's out there
    https://www.google.co.uk/webhp?sourc...ental%20system
    but no one pre existing template is going to 'advance' your design unless you have a clear idea of what the design objective is.
    what are you drawing this erd for
    what are the key requirements to meet those objectives.
    until you have a clear idea of what those objectives are then non one can 'advance' the design not even you.
