I've been trying to understand how to identify the rules. This is by far the only thing ive seen that made it easy to understand normalizing databases and how to break them down. Thank you sir!

A fantastic and easy to understand explanation of normalization as a whole, and how each level of normalization (1st to 3rd) differs. Thank you very much.

Thank you for this tutorial, The third rule (country, city…) Generally what i prefer is to put city id, state id , country id in the same table to directly and joins them in one query, i believe that reduce the complexity of getting data.

I swear every video on this topic has different definitions for 1NF

Orderitems stores the quantity and price per unit. Orders stores ordertotal, which is a derived attribute (sum of the ordered items*quantity). I'm curious why you chose to store the ordertotal in the table, should we not remove derived values in 1nf?

Not the best example. If you don't have a composite key, then your table already is in 2NF. Instead, what you're showing here is basically 3NF, not 2NF.

Exactly. He basically did 3NF twice

Hello there, glad to meet again. I have a simple enquiry.. In what case it would be convenient to apply BCNF form of normalization to my data? Thanks for taking care of this.
@thebulletkin839311 ай бұрын
isn't the third normal form just the second but done again? Since it just has you checking through to make sure that all the non key values depend on the primary?

around 5:00 mark, wouldn't you say that "Address" is not yet an atomic value, thus not meeting 1NF?
