    DB Functional Dependency, Candidate keys and 3F

    Hi, i am having issues with this problem.

    A B C D E F G H I J K L M N

    Firstly i need to check if these functional dependencies i came up with are correct and provide minimal cover.

    A>BCD
    C>F
    B>G
    D>E
    BD>AH
    I>J
    K>LI
    M>N
    NI>MK
    MK>I

    Is this right?

    In addition to this, could someone tell me what the candidate keys are?
    I am assuming that A is the primary key.

    Thanks
