Find the highest normal form.
AB - - > CE
E - - >AB
C-->D
Doubt
AB, E are the candidate key.
The answer given is 2NF
In 2NF, there should be no partial dependency which is
PRIME ATTRIBUTE - - >NON PRIME ATTRIBUTE
But it is there in AB-->CE, I think CE is non prime attribute.
Or bcoz of E we consider them as prime attribute.
