Topics covered:

What is Normalization?

Objectives of Normalization

Types of Anomalies (Insertion, Update, Deletion)

First Normal Form (1NF)

Why 1NF Exists

Conversion Principle

Second Normal Form (2NF)

Prime vs Non-Prime Attributes

Partial Dependency (The Root Problem)

Third Normal Form (3NF)

Transitive Dependency

Why Transitive Dependency is Dangerous

Boyce-Codd Normal Form (BCNF)

Fourth Normal Form (4NF)

Fifth Normal Form (5NF)

Referential Integrity

You’ll understand how normalization eliminates redundancy, prevents data anomalies, and ensures logical database structure. These concepts are crucial for backend development, database architecture, and technical interviews.

If you want to design clean, scalable, and efficient databases, mastering normalization is essential.
