[@krishnachaitanya5965]

This is the best video I've seen so far. Great content for beginners.

[@MarkBelain]

At first, I disliked the video because I felt it was skirting around the actual core topic of ETL” Right around 5:30, though, everything you said came together and this just became one of the most elegant ways to explain ETL that I’ve seen so far. Suffice it to say, I went back and put a like back on the video.

[@codebasics]

Ha ha.. thanks mark for showing Patience 👍😊

[@tejrupsai7396]

The best explanation that I have ever seen it's very simple to understand and most of the information has been explained within few minutes.

[@wallysonruan4246]

As some already said, I've watched lots of video before landing here but you were the one to make me go "mind blowing". Thanks a lot, man! Special compliments for the way you designed your representation of the pipeline as well as the difference between OLTP and OLAP!

[@jayasriravisankar4059]

Awesome video, As everyone said , i have watched several videos and several documents to learn these topics, None of them have cleared all my queries on my mind in regards to these terms, but you made me to understand it so easily. Thank you

[@AnkitChoudhary-st2is]

BEST OVERVIEW VIDEO, BIG THANKSS!

[@saumyasrivastava4064]

10 out of 5 STAR for the explanation and the way you taught it. Compelled me to comment for the first time on any educational content. I really feel a teacher, a mentor should understand his audience first, talking about things in your jargons/terminology is easy but explaining it in a way where even a non-technical person can understand the business value behind it, is RARE. You absolutely did that! The way you started it with business case, added crisp context before bringing the jargon and then connected it all, was just super awesome. Please keep up the good work! Inspiring! P.S. Sorry, I understand the efforts that goes behind making these videos but mostly other videos (of other people) are like; you extract from database, you transform and then you load for analytical purpose - this is ETL. Such videos should add a disclaimer - intended for audience with tech background.

[@ad3]
