Question
Which forms has a relation that possesses data about an individual entity:Options5NF3NF2NF4NF
Solution
The forms that a relation possessing data about an individual entity can have are:
-
2NF (Second Normal Form): A relation is in 2NF if it is in 1NF and every non-prime attribute of the relation is fully functionally dependent on any candidate key of the relation.
-
3NF (Third Normal Form): A relation is in 3NF if it is in 2NF and no non-prime attribute of the relation is transitively dependent on any candidate key of the relation.
-
4NF (Fourth Normal Form): A relation is in 4NF if it is in Boyce-Codd Normal Form (BCNF) and it has no multi-valued dependencies.
-
5NF (Fifth Normal Form or Project-Join Normal Form): A relation is in 5NF if it is in 4NF and every join dependency in the relation is implied by the candidate keys of the relation.
These are the forms a relation can have when it possesses data about an individual entity.
