Like this is straight up amazing! I sat through lectures on this topic given by a bad lecturer thinking I was a moron for not getting it. Watched a 20 minute video by this legend of a man, and it's like someone turned a light on in my brain for how we normalize, and why. You just earned yourself a sub!

[@ghulamhassanhassani8465]

William Organ, I cannot be more agree with you

[@victherocker]

Good students aren't just good on their own. Half of their results come from good teachers like this.

[@kalMHe]

OMG.. you taught me a lot here, but the Mortgage Freeman part killed me man ! I hope Mortgage Freeman watches this video !

[@dakneedeeder]

Thanks for this great video. The names are hysterical. Concise explanation of normal forms.

[@foggianism]

Bread Pith is my favorite.

[@walimorris2406]

Literally the BEST video on RD normalization! In 21+ mins you broke this process from bottom - up. You went over the small details, where does the primary key come from, what is CUD anomalies and how to satisfy 1NF++. You answered al our questions, the reason we came here. They say you truly know something when you can explain it in a very simple way, given this is not rocket science and is capable of explaining in simple ways, you sir have accomplished that! Thankyou! P.S Thanks for adding the subtitles!

[@shanilkakuruppu4932]

One of the simplest videos to understand database form normalisation. Thanking you, all the way from Sri Lanka.

[@jennylenesmith-drayton8677]

I have looked through lots of material on NORMALIZATION and this has been the **BEST** explanation. Great Job!!!

RIP Gori Diamond 1967 - 2017

[@swapnilnair3342]

[@chamelion100]

[@shaunonmt]

He sent Morgage Freeman to the moon.

[@ghme4421]

ROFL LMAO... Yes, He killed GORI Diamond... That's homicide...

[@rodanm]

@@shaunonmt betterrr

[@mcjb73]

I have never had someone explain something to me that was as clear as this presenter did! Excellent job! Now I would like to see how to move a database into the next forms! But only by this guy..absolutely amazing!

[@SHOAIBKHAN622]

What I like about your videos is you make things so easier and explain technical things in simple words.

[@breakpoint6752]

I had seen many videos on Normalization before this and still was not confident on the concept. Loved the simplicity with which the concepts were covered. Confident and satisfied :)

[@chauharyfaisal1616]

Before this lecture, many teachers guided me how to normalize the data. But this lecture is awesome. My all concepts about normalization are cleared in just half an hour. Excellent And Great Teacher. Thank you so much!

[@mihlalisixolo6240]

straight to the point. I am studying database introduction as one of my modules and this video helped alot

[@chikangeng7208]

Thank you for explaining. Only 20 minute and I master 0NF to 3NF already! Thank you so much!

[@yuvrajoberoi7834]

You have explained this really well. All other youtubers are just giving examples with those arrows and relations etc. but you took a real world example and explained it.

[@BBarters]

Thank you for your kind words.

[@aaliquegrahame7957]

Shoutout Mortgage Freeman lmao

[@michaelbartnicki9464]

Hey man don't forget about Bread Pith!

[@ParadiseBiker]

For sure, LOooOL!

[@justjase10]

Was he referencing the Boondocks😂, as in Morgan Jebediah Freeman?

[@ummemarzinajotey7616]

Don't know how to thank you! U made it understandable in 21 min which my professor couldn't do in 3 hrs.. make more videos like this. God bless u!!

[@riyagoswami4925]

6 Feb 2020: Before watching this video, I was clear with most of the normalization process. Still I was making occasional mistakes. The part of your video that helped me a lot is : To find out if the non-key columns are dependent on primary key, ask this question, does that non-key column describe what the primary key identifies? If the answer is "no", that information should not be in that column. Thank you very much :)

[@imadkhan7420]

Watched many videos on this topic, this is by far one of the better if not the best one! Much appreciated.

[@aidangasim]

tons of people clarified it on youtube but noone did like you,big respect thank you Man!!!!!

[@avinashkumar6327]

ONE OF THE BEST EXPLANATION OF NORMALIZATION I CAME THROUGH ON KZbin.........

[@ibrahimal-mahfooz8737]

One of the best on KZbin. Thank you.

[@BBarters]

Glad you think so!

[@bralabala]

to think this video was made in 2017 and it made the most impact to my understanding of the subject in 2022. thank you.

[@StarGEntertainment]

after 2 years at collage not understand normalization, but i was able to put my tables into the 3nf (i know its werd). i was final able to understand normalization perfectly. this video saved my life as its the best one out of all the normalization videos ive watched, thank you so much

[@sandramaniscalco4887]

This was a very helpful video. I had been reading through a lot of material prior to this and it just was not making sense to me. Your explanation cleared up all my confusion! Thank you!!!

[@maclife1321]

literally after going through 4 other videos from different people explaining Normalization, you got the best explanation thanks man keep it up.

[@Sakshi_suman16]

best video ever thanks from Australia😃

[@iliasp4275]

how can you keep a straight face saying things like "Mr bread pit" ? I love you !

[@BBarters]

I have a lame face!

[@investigate3_11]

This video is fantastic. I thought he genuinely didn't know how to pronounce those names but then I saw him doing the same with Indian names so I'm sure he's just messing with us. This video had me in stitches at times! Also, more importantly, I've gotten a good overview of what normalisation means. Thanks, man!

[@brandenvs]

This really helped ! You dont rush through things and very easy to listen to.

[@BBarters]

Thanks a ton Branden for your kind words.

[@alphacoder3822]

1 hr Nptel and 2 hrs of my university class couldnt make me understand this topic but your videos made me understand everything.

[@BBarters]

Fantastic video. Thank you from Australia :)

[@hamzahahmad1670]

I just noticed, you typed the subtitles for this video yourself, right? Dedication, right there. Great video.

[@kartiknand4357]

I actually wanted the video to explain about the BCNF (Boyce Codd Normal Form) which comes before the 4NF. The video shows a thorough explanation of the concepts, thank you so much.

[@kartiknand4357]

At around 13:49 of the video, he said that if a customer is removed from its table, the agent will not be affected. My question is, what if the Primary Key of the Agent table is a Foreign Key in Customer table and Referential Integrity is enforced and Cascade Update and Delete Related Fields and Records is checked in the Relationship, will it affect the Agent's table in any way?

[@sunnysunde3495]

That is one handsome teacher! Thank you for the lessons.

[@DayeetaDasdona2012]

Brilliant video. Thank you so much for the wonderful explanation.
