Complete DBMS Normalization in 8 Mins | 1NF, 2NF, 3NF & BCNF | GATE CSE 2026

Описание: In this video, we simplify the core concepts of Database Normalization to help you secure those crucial marks in the GATE CSE exam. We break down the rules and violation cases for 1NF, 2NF, 3NF, and BCNF based on the latest technical patterns.

What you will learn in this video:
1NF First Normal Form: Understanding Atomic values and why default RDBMS is always in 1NF.

Partial vs. Full FD: Mastering the building blocks of 2NF.

2NF Second Normal Form: How to eliminate Partial Dependencies and identify violation cases.

Transitive FD: A deep dive into dependencies where one attribute depends on another non-key attribute.

3NF Third Normal Form: Rules for Non-Trivial FDs and identifying non-key to non-key dependencies.

BCNF Boyce-Codd Normal Form: The strictest form where every LHS must be a Super Key.

Redundancy Comparison: Why 1NF has more redundancy than 2NF, 3NF, and BCNF.

Key Highlights:
Lossless Join is maintained across all forms.

Dependency Preserving status for each Normal Form.

Violation Case analysis for quick problem-solving in GATE.
