    BCNF and Candidate Key ?

    Hello Friends,

    I have a question ?

    If a determinant is part of a candidate key is that good enough for BCNF ?

    thanks,

    No, not if the determinant doesn't include the whole candidate key. A relation is in BCNF if and only if every non-trivial determinant is a superkey.
