Comprehensive Guide to Database Normalization and Normal Forms

This lecture series covers the essential concepts of database normalization, including the definitions of keys and attributes involved in keys. It delves into further details of the First Normal Form (1NF) and the processes for normalizing nested relations into 1NF. Additionally, it explores the Second Normal Form (2NF) and Third Normal Form (3NF), providing practical applications and examples. The material is structured to enhance understanding of normal forms and their significance in database design, ensuring relational consistency and efficiency.
