Data Scientist - Learn Database Normalization - 1NF, 2NF, 3NF, 4NF, 5NF

Want to go deeper? I wrote a comprehensive e-book that covers everything in this video — plus more step-by-step detail, BCNF/4NF/5NF in depth, exercises and solutions. 📘 Get the complete guide → https://decomplexify.org/e-dbnorm ───────────────────────────── IN THIS VIDEO This easy-to-follow database normalization tutorial makes use of lots of examples and focuses on the design process. It explains the "why" and "how" of normalization, and takes you step-by-step through: • First Normal Form (1NF) • Second Normal Form (2NF) • Third Normal Form (3NF), with a side note on Boyce-Codd Normal Form (BCNF) • Fourth Normal Form (4NF) • Fifth Normal Form (5NF) ───────────────────────────── WANT MORE? My guidebook, DATABASE NORMALIZATION MADE SIMPLE, takes everything here further: ✔ In-depth, step-by-step explorations of the normal forms starting with 1NF and its nuances (atomicity, etc) ✔ Exercises and solutions at the end of each normal form section ✔ Boyce-Codd Normal Form and why it is in some sense the most important normal form of all ✔ Extensively reworked and expanded material on 4NF and 5NF, projections and join dependencies ✔ 🎁 BONUS included with the guidebook: Interactive SQL facility featuring tables with normalization issues 📘 DATABASE NORMALIZATION MADE SIMPLE → https://decomplexify.org/e-dbnorm ───────────────────────────── Video Timeline: 0:00 What is database normalization? 3:55 First Normal Form (1NF) 10:24 Second Normal Form (2NF) 16:08 Third Normal Form (3NF) 20:29 Fourth Normal Form (4NF) 23:47 Fifth Normal Form (5NF) 26:41 Summary and review Corrections can be found in the pinned comment. 👉 You can also download a FREE PDF (Decomplexify Quick Reference Guide), with cheat sheets covering 1st, 2nd, and 3rd Normal Form, plus Entity Relationship Diagram (ERD) conventions: https://decomplexify.myflodesk.com/wm7ixaj2x6
