Suppose we have a table named "Books" with the following structure:Book ID Title Author Genre1 The Great Gatsby F.

Solution
The final step to achieve 1NF (First Normal Form) for the "Books" table is to separate genres into individual rows. This is because 1NF requires that each column of a table has atomic (indivisible) values. In the current "Books" table, the "Genre" column has multiple values in a single row (for example, "Fiction, Dystopian"). To achieve 1NF, these values need to be separated into individual rows.
