  • @suryaajha5953
    @suryaajha5953 5 років тому +2

    This was the most correct video logically as the explanation of all these keys. I was always with these keys and thought these concepts are just to confuse readers. Thanks Sanchit Sir.
    As a short note
    Super key us the set of attributes from which you can uniquely identify a row or a tuple in the table.
    Key = Super Key
    Candidate key is the super key whose proper subset itself is not a super key.
    A Primary key is candidate key selected by DBA as a primary key to identify a row or a tuple in the DB

    You can use augmentation in D -> A and transform it into DB -> AB. Then transitivity can be used with AB -> C to give DB -> C which can then be unioned with DB -> ABC to give DB -> ABCD which is a super key.
