Calculate tables for 2NF & 3NF; given that the table is in 1NF & has the functional dependencies shown below:

1NF Tables:

T1(A,B,C,D,E) is already in 1NF form

Functional dependencies:

A,B -> C

A is a Partial Composite Key1

B is a Partial Composite Key2

A&B form the composite key because

(AB)+ =ABCDE

Partial composite key1, Partial composite key2 ->non key attribute1

................full dependency

C -> D

C isnt a candidate key; its a non key attribute (Nka1)

D is a non key attribute

non key attribute1 -> non key attribute2

................transitive dependency

B -> E

B is a Partial Composite Key

D is a non key attribute

Partial composite key2 ->non key attribute3

.............partial dependency
