1) Consider the relation R, with key and functional dependencies shown below. i. What Normal form is R in right now? Why is this the case? ii. What actions would you take to normalize R to the next higher normal form? (Describe the steps) iii. Follow the steps you described in the prior question to normalize R to the next higher form. Be sure to show all of the steps. iv. Once you have normalized R, what normal forms are each the two new relations in? Why? v. If any of the remaining relations are not in 3NF, normalize them to 3NF. Be sure to show all of your work

R ( t, u, v, w, x, y, z ) Key: t, u

FD1: t, u v, w, x, y, z

FD2: u v, w

FD3: x, y z
