Question
A relation with 2 attributes is always in _______.a.1NFb.3NFc.2NFd.BCNF
Solution
A relation with 2 attributes is always in 1NF, 2NF, 3NF, and BCNF.
Here's why:
1NF (First Normal Form) requires that each attribute value is atomic, which means it cannot be further divided. A relation with 2 attributes will always meet this requirement.
2NF (Second Normal Form) requires that every non-prime attribute of the relation is functionally dependent on the whole of every candidate key. In a relation with 2 attributes, there is only one candidate key (assuming the attributes are not identical), so this condition is always met.
3NF (Third Normal Form) requires that every non-prime attribute of R is non-transitively dependent on every key of R. In a relation with 2
