Normalization in relational databases serves what purpose?

Normalization in relational databases serves what purpose?

• A. Encrypts data during transmission
• B. Organizes data to reduce redundancy by structuring tables and relationships
• C. Duplicates data across multiple tables to speed up queries
• D. Converts binary data into text

Answer: (B)

Normalization focuses on organizing data to minimize redundancy and dependency by dividing information into related tables and using keys to connect them. This structure ensures that each fact is stored only once, so updates, deletions, and insertions don’t create inconsistencies. By separating entities like customers, orders, and products into distinct tables and linking them with primary and foreign keys, you reduce duplicated data and make the database easier to maintain. The other options miss the essence: encrypting data during transmission is about security, duplicating data across tables creates redundancy, and converting binary data to text is an encoding issue rather than data organization.
