Database Normalization 1NF 2NF 3NF

Data Normalization is the philosophy and mathematics for understanding and connecting data, and is a core stepping stones for becoming a data professional. This video explains the history of normalization, and how to normalize data to first normal form (1NF), second normal form (2NF), and third normal form (3NF).

Got a databases exam tomorrow for uni. This has really came in clutch since I've always struggled to understand the differences between 1NF - 3NF. Cheers!

This video taught me normalization in 10 min, but my lecturer spent 1 hour confusing me

There cannot be more simplistic explanation on normalization than this video. It took me years to find this short but exceptional tutorial. Thank you!

I had a class in the morning hours about normalisation and woke early to watch this. It has been very helpful to me. Be blessed alot.

YES! I have listened / read / watched some 10 other explanations that seem to use absolute gibberish for this concept. But yours is immediately crystal clear. I finally understand 3rd Normal Form. Thank you so much.

There's at least a one guy on educational videos saying they didn't get anything from lectures.😅

So here I am, Thank you, this video helped me a lot.

I have a Microsoft Access exam tomorrow and I was struggling a lot with normalisation. You explained it well and now I have a decent understanding of what I have to do. Thank you!

[JessiesGengar]

This is so helpful!
i've been struggeling to understand this particular part of the course i'm following for the past 3 days, and you have made it very clear in 10 minutes.
it's clear, with a simple visual and without all the extra's which just confuses the main point.

TY so much, i can continue my course with confidence!

Omg I was sobbing trying to figure out my assignment until I found this video. It's the only video I could find that used an example I could understand! 😭

[ED-zqtq]

well explained, straight to the point, No extra or less info . Thank you sir.

[kareemsharawi]

This is just amazing the way you describe things! I come here after failing to understand NF through an instructor of a well known EXPENSIVE online educational platform (will not mention the name). Thank you very much!

[Alfenijonas]

Nice examples and explanations. Everything goes from start to end, without any "side quests". The explanation is fluent and has a flow. Like a well-written book. Clicked that like button and spent some time writing this comment in hopes that the yt algorithm will show this to as many people as possible.

Finally, somebody! I've needed this video for such a long time, thank you.

[feimimi]

[dude_mude]

I got a CS exam next week, ur A LIFE SAVER!!!

So useful! I could not understand anything from my classes at uni before this
