Question : We have a relational model represented as a relational schema and its functional dependencies given as below:

Assignments(A, B, C, D, E, F, G, H, I, J, K, L, M, O)

fd1: A, B, C -> D, E, F, G, H, I, J, K, L, M, O

fd2: A -> D, E, F, L, M, O

fd3: B, C -> G, H

fd4: D -> L, M, O

fd5: L -> M

fd6: G -> H

1. Is this relational model in 1NF? Why? If not, normalize it to 1NF. Make sure you list ALL relations after the normalization process; and for each relation, list the functional dependencies.
2. Is this relational model in 2NF? Why? If not, normalize it to 2NF. Make sure you list ALL relations after the normalization process; and for each relation, list the functional dependencies.
3. Is the relational model in 3NF? Why? If not, normalize it to 3NF. Make sure you list ALL relations after the normalization process; and for each relation, list the functional dependencies.
