30. Database Normalization Completely Explained (1NF, 2NF, 3NF, BCNF) with Solved Problems

In this video, we cover Database Normalization completely — from the absolute basics of data anomalies and Functional Dependencies to advanced decomposition and BCNF — with real-world examples and solved problems for every single topic. This is everything you need to organize database schemas effectively, eliminate redundancy, and ace your DBMS exams or interviews. 📚 Topics Covered: 0:00 Introduction to Normalization 1:07 Understanding Data Redundancy and Anomalies 6:05 Functional Dependencies Explained 12:24 Types of Functional Dependencies 18:44 Transitive Functional Dependency 20:03 Armstrong's Axioms 25:04 Attribute Closure and Candidate Keys 35:03 Canonical Cover and Minimal Cover 46:31 First Normal Form (1NF) 49:08 Second Normal Form (2NF) 59:09 Third Normal Form (3NF) 1:07:38 Boyce-Codd Normal Form (BCNF) 1:14:10 Denormalization Explained 📌 Why This Video? Most tutorials only define 1NF, 2NF, and 3NF at a high level and skip canonical covers, formal mathematical definitions of 3NF/BCNF, and step-by-step table decompositions — the exact problem-solving skills tested in university exams, GATE, and technical interviews. This video covers ALL of it, with clear diagrams and worked-out examples for every rule. 📥 Resources 📌 Download Notes: https://drive.google.com/file/d/1Nvkj... 📌 MySQL Complete Course -    • MySQL Complete Course — Zero to Advanced |...   📌 Python for Data Science & Machine Learning Complete Course -    • Python for Data Science & Machine Learning...   💬 Got a question?
