Database Normalization #5 – HackerRank Solution

In this post, we will solve Database Normalization #5 HackerRank Solution. This problem (Database Normalization #5) is a part of HackerRank Databases series.


Consider the following relation and determinants.


                   a,c -> b,d
                   a,d -> b
        Also, a,b is a primary key for the above relation.

The above relation is in x NF form where x may take the following values {1,2,3,3.5} corresponding to {1NF, 2NF, 3NF and BCNF} respectively.
What is the maximum possible value of x such that the above relation satisfies the *x*NF form?
Your answer should only be restricted to one of these numbers:1/2/3/3.5 Do not leave any leading or trailing spaces.
