Primary & Foreign Keys

[@meilyn22]

These students have no clue how lucky they are to have this teacher.

[@pauclairtameze9893]

Really.

[@blippityblop2012]

I literally just said to a friend, "I wish he was teaching our course."

[@Cneq]

My lecturer belongs in a room doing complex data analytics and not in a class room lmao he obviously knows his stuff but just because someone knows their stuff doesn't mean they make a good teacher.

[@abbagurl1892]

8 minutes vs 16 weeks....the difference is astounding. Nearly a decade later and this video is still teaching. Thank you for being such an engaging teacher and sharing it with the world!

[@UrmatG]

Just curious, what does '16 weeks' represent in your comparison?

Thank you, SO MUCH! I just began my MIS college course and I've been having a hard time finding the importance of studying this material. You helped me snap out of that tedious/bored phase and get engaged. God bless you, sir.

[@bionicmagi6388]

Thank you SO MUCH, I'm in the middle of a data analytics coarse and they were using language and examples that just were NOT clicking. The way you explained the unique identifier and how it connects to another table just made everything click, you have no idea how happy I am to finally understand.

Australia is lucky to have intelligent people like this, thanks for being here!

I'm a data scientist who is new to the field, I have a math degree and would watch some of your videos during college, you continue to be one of the best educators on this platform, especially for someone trying to learn DB concepts :) cheers man

[@peacegrace6141]

Before finding this video, I stayed awake all night last night and slept at 6am coz I am trying to learn this topic for a discussion. I do not have an IT experience. Let me tell you, this is by far the simplest explanation I dug and really hoped I found this last night! You are an amazing instructor. You made it so easy to understand! I'm a fan!

[@jammindrewfish4186]

1:13 dude really interrupted him just to tell him he made a spelling error -_- I wouldn't last more than a week as a high school teacher... Thank God for people like you!

[@Numizard]

That's not a spelling error he literally didn't write the right word which showed to be really confusing. The prof even joked about it. Did we watch the same video ?

[@jammindrewfish4186]

@@Numizard Given the context of the lecture along with the fact that the student who asked the question clearly knew he meant "keys" instead of "cables", it's obvious that he only pointed this out because he felt like speaking out. Not because he was truly confused. You may not know this, but this isn't uncommon amongst high school students in the US. So, we did indeed watch the same video -- The only difference between you and I is that I was raised to hold the upmost respect for my elders and for educators, you were not.

[@darkwoodmovies]

I legit have been working with DBs for a while. I knew all this stuff in my head but never put the names to it, and it's so obvious now... but until this video I couldn't tell you the definition of primary and foreign keys. Just goes to show how a clear explanation can make all the difference.

[@Peachezz507]

You are an awesome instructor....I got it just like that. I was always unclear of the 1:1 1:M and M:M.

I don't think it's that, it's just click bate. I mean I saw videos titled for instance "Databases - English", so I would think it would be in english, then when I click on the video I can't even understand him so thats it.

[@ssshah3333]

You're just mad that Indians dominate the tech industry

[@thevikesh]

Product columns should also be converted as a separate table basically you can have two more tables 1) Product-master table and 2) Order-Product table where OrderId and ProductId can make a composite key so that if a customer wants to order multiple products (let say 10 different product) in a single order he can do so else he has to create multiple orders. Order-Product table can also take care of quantity and price. Namaste 🙏🏻

[@thevikesh]

This is nice explanation of primary key and foreign key 🙏🏻

[@Klonzo33]

I can't believe how easy this concept is with a teacher who presents it this way. My professors were more annoyed that they had to explain this stuff
