Final answer:
2NF requires non-primary key columns to depend on the primary key, reducing redundancy and improving data integrity.
Explanation:
Second Normal Form (2NF) differs from First Normal Form (1NF) by requiring that any column, not a primary key, must depend on the primary key. This reduces redundancy by eliminating the potential for multiple primary keys throughout multiple tables. Achieving 2NF in database design results in more efficient storage of data and reduces data anomalies.
