This is lecture I wish my professor would have given! Thank you, Snir!

We had a course on DW last semester (in BGU) , I'm preparing for a Data Engeneering interview and I think I've learned more from this video than I did during the whole semester.

very nice and more practical then what they show in class, Amazing !!!!

Thanks, Snir. You covered a lot of ground in 30 minutes....but everything was clearly explained.

i crammed this right before my data engineer interview thanks!!!! Everything you covered here was asked in some ways.

Thanks you. Well explained with appropriate examples. Keep up the good work.

Thank you for the lecture. I am so confused; Dimensional modelling, Kimball modelling and Star scheme are the same or they have differences ?

Very insightful. Thank you!

Such a great video! Helped me with my exam so much!

Hi, Thank you for the amazing video! Really insightful! I was wondering about one thing you mentioned in OLTP section about data being inconsistent. Aren't ACID properties used for that purpose so that data is always consistent in OLTP? Let me know what do you think.

Great tutorial

It is very much informational ! Thank You !

Great video. One question: can you go the OLAP route and use that to design the schema for your primary data store for your application?

Good job! You are good.

OLTP is a relational system for day to day transaction.. I will say Bill Inmon normalization is the best method.

Thanks for the excellent video! With the advent of columnar database, power BI, tableau, are there any changes required in modelling techniques?

Great explanation! Thank you!
