Question: Consider the relation R ( W , X , Y , Z ) with a set of functional dependencies F given by: 1 . WY

Consider the relation R(W, X, Y, Z) with a set of functional dependencies F given by:
1.WY ->X
2.X ->Z
3. Z ->Y
4.W ->Y
1-Find the minimal cover of F.
2-Calculate the closure of {W}.
3-Determine the candidate keys of R.
4-Analyze the normal forms. Based on your candidate keys and the minimal cover, determine the highest normal form (1NF,2NF,3NF, BCNF) satisfied by the relation R.
