I remember this was first video i saw and i decided to become ETL developer after seeing that video just clear some concepts from that day to now after lots of hardwork a ETL developer. Working on talend, matillion, informatica and abinitio. This journey is quite amazing.

[@codebasics]

[@sahilkadu5409]

ur really great teacher. I learnt a whole warehouse tool without understanding what warehouse and ETL actually does is. and here this 8 min video explained me in the best way possible.

[@codebasics]

👍👍🤗🙏

[@johnblackstockmusic]

Appreciate this video! We're learning ETL in my Business Intelligence class and this summed up an entire chapter in 8 minutes!

[@codebasics]

Glad it helped John

[@rayray7244]

I'm telling you if I had to do it over again I'd get my education from KZbin and Udemy! Would've saved me 100k in student loan.

[@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 👍😊

[@sumanthaddala6924]

Thank you very much sir🙏, the concept which you've explained is crystal clear, very calm and on point without fogging brain.

[@p.sarankumarpatro9773]

[@ravikishorergajavalli]

Nice explanation. Non IT guy can easily understand the basic information about all these terminology. Thank you for sharing your knowledge.

[@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.

[@trikavyam8101]

Very good explanation.....before this video i had lot of confusion on elt but now its very clear...thanks

[@anika7277]
