Third Normal Form (3NF) | Solved Examples 1 & 2 | Normalization | RDBMS

## **Topic:** *Third Normal Form (3NF) – Solved Examples 1 & 2*

In this video, we solve **two complete problems** on converting relations into **Third Normal Form (3NF)** using a clear and exam-oriented approach.

You will learn:

* How to identify **Transitive Dependency**
* How to check whether a relation satisfies 3NF
* Step-by-step conversion from 2NF to 3NF
* Proper decomposition technique
* How to preserve dependencies while decomposition
* Important exam tips and common mistakes

In these examples, we apply:

* Functional Dependency concepts
* Candidate Key identification
* Attribute Closure
* Removal of transitive dependencies

This topic is very important for:

* Database schema optimization
* Removing redundancy and anomalies
* Understanding higher normalization (BCNF)
* University examinations
* Competitive exams (GATE basics)
* Technical interviews

3NF problem-solving questions are among the most frequently asked topics in **DBMS exams**.

These examples will help you develop a **strong and systematic normalization approach**, making complex problems much easier to solve.
