Thanks a lot, as a beginner to this concept why is Customer ID not the Primary key?

Thanks!

Very clear explanation

I think a game can definitely be within multiple seasons in a different year! However, within the same year, a game will only ever be in one season, like how Basketball is in winter. I feel like either answer is fine, but you have to make sure you have words between tables to help understand the relationship/

Dear Justin, Thank you so much for the brilliant videos on Normalization. It is the best resources and explanation about Normalization out there. I am using these videos to teach Normalization to my students in Year 12 Computer Science over here in Australia. I was wondering if you could share some Normalization exercises that you use at Uni for your students. It is very hard to find good flat file to normalize to 3NF with answer key. I would appreciate if you could share a few Normalization exercises similar to the examples that you use in your videos. With Thanks Regards

For multivalued attributes how it becomes one-to-many, I think it should be many-to-many because An employee can have multiple skills and A skill may be owned by many employees Also in the nurse and care center example is it the care center the optional or the nurse regarding to erd

In my college they taught us that we have weak entities my question is Should I just not use it? Also Should I use surrogate key instead of composite primary key and why?

Thank you so much, actually this short course is very useful, and I want you to advise me please where to go next to master ERD..

Thank you, simple and short video. very helpful

This is so helpful. Keep up the good work, Dustin!

Where was this video, I mean I have been struggling with this and getting more confuse with other TH-cam videos but this right here is magic, thank you sir

why do you sound like chris chan it took me a while to concentrate because of this😂😂

This helped me so much indeed. Thanks a lot! Great video! 👍👍👍

why is the Code considered a Primary Key?

I wish I had seen your channel before I spent much time understanding this concept. Expert decomposition.

I have a midterm tommorow on this chapter and you honestly put together everything , it made sense, it had all the content I needed to learn. thank you so much truly. It is hard enough to find content when you are a university student and i appreciate your efforts!! :) stay blessed. 😁

On line 50, where you have `Count(o.order_id)` I've recently been shown it is more performant to NOT use the primary key if other non null fields exist, with `Count(o.*)` actually being perfectly fine despite myths to the contrary. Something to do with PK fields beings stored in a more robust format that has some additional overhead.

I'd argue that players might not always need coaching and might self train as well, so it is probably optional-many. Anyways, excellent video, made me understand the concept pretty well. Thank you, justin

THANK YOU KING 👑

What program did you use to draw those tables in. It looked like a super helpfull tool to get an overview when working with databases

this was really helpful! Thank you so much :)

Better than my $60k a year private college professors

Thank you so much. Your playlist on normalization is so easy to follow and understand :)

Thank you :)

Perfect and to the point, Thanks.

very concise and easy to follow, yet, execise is very important to help to get works done
