MySQL Normalization Explained | 1NF, 2NF, 3NF Forms with Simple Examples | Session #3

Описание: In this video, you will learn the complete concept of Normalization in MySQL in a simple and practical way. Normalization is a database design technique used to organize data efficiently in tables so that data redundancy is reduced, data integrity is improved, and anomalies (update, insert, delete problems) are removed.

We will start by understanding what normalization is and why it is important in MySQL databases. Then we will move step-by-step through each normal form:

✅ First Normal Form (1NF)
You will learn how to convert an unstructured table into a structured one by:

Removing duplicate columns

Making sure each column contains atomic (single) values

Ensuring each record can be uniquely identified

✅ Second Normal Form (2NF)
You will understand how to:

Remove partial dependency

Separate data into multiple related tables

Use primary keys correctly

✅ Third Normal Form (3NF)
You will learn how to:

Remove transitive dependency

Create a clean and optimized database structure

Make your design suitable for real-world applications

We will also discuss different types of anomalies:

Update anomaly

Insert anomaly

Delete anomaly

Each concept will be explained using easy real-life examples, table structures, and MySQL queries so that even beginners can understand and apply it in their own projects. This video is very helpful for students, developers, and anyone who wants to build a strong foundation in Database Management Systems (DBMS) and MySQL.

By the end of this video, you will be able to:
✅ Design efficient tables in MySQL
✅ Avoid data redundancy
✅ Improve database performance
✅ Understand real-world database design logic

Perfect for: Beginners, SQL learners, college students, and backend developers
