I'm from China and it's frustrating that you can't find any video doing a good job explaining knowledges about DWH, glad I found this on YouTube. Cheers!

@sandrafield9813

Thanks for this description! Its better than all the other ones I found.  Its more clear with extra details without being convoluted and messy.

@macellit

Excellent content and very well explained. Thank you

@Pasdpawn

man I spent a fortune to get an IT degree and here i am , learning it from a youtube tutorial which is far better and easier to understand than my database lectures. thanks a lot sir for your effort.

@MuhammadMustafa-rd6vg

this is a good tutorial , watched dimensional modelling & SCD tutorial, you were pretty clear , explained in detail without making it boring !

@cluebcke

This is really awesome, thank you so much. Just to add, one use case for Type 5 (which I had no idea was called Type 5 before watching this) is that if you have a lot of data in a record that doesn't change much, and only a few fields that change a lot, partitioning them into different dimensions can substantially reduce table bloat (as you're not creating many copies of unchanged data) and improve query performance. There are tradeoffs of course and you really have to evaluate (and test empirically) for your use case.

@kopaczp

Great explanation! This channel deserves for more views !

@guillermopalaciosgaray

Thanks for your explanation! This is the best video I've found :)

@maisamabbas6872

This is the best explaination for slowly changing dimensions that I've come across on Youtube. You definitely deserve my like and subscribe. Thanks for such an amazing video. I hope you make a lot more videos on Data Engineering topics.

@houstonfirefox

Great explanation Bryan w/real-world examples and analogies. New sub!

@thoroth_

This is the best explanation of this concept that I’ve seen, thank you so much

@helovesdata8483

you've helped me to understand data warehouses more

@shivam6565

Thank you Bryan for this wonderful tutorial. Concept lucidly explained and I like your teaching style. Liked and subscribed.

@sauravmisra6061

Thank you sir for explaining the code EDW concepts in both the videos - Dimensional modeling and SCD, so well and precisely. I also followed your Databricks and Spark and these are the best I have found so far on these topics. Thank you , sir and really appreciate your effort.

@marcosoliveira8731

Topics like this still so relevant.
I hope you have more to share about DW Architecture.
