- In this video, we will discuss what is ETL (Extract, transform, load), what is data warehouse and the purpose of it. The difference between OLTP (Online Transaction Processing System) vs OLAP (Online Analytics Processing System). Apache nifi, talend, informatica are some the entreprise ETL tools whereas for data warehouse teradata, amazon redshift, snowflake, greenplum etc are widely adopted in the industry.

Wow, you're a really great teacher. It's very clear and concise. Thank you!
Glad it was helpful!
I went through lots of Google search and read this topic but it was not clear to me but you made it very simple and I got overall idea of main 3 topics 1) ETL 2) DW and 3) OLTP &OLAP just in 8 minutes ...Thank you
👍☺️
I totally agree , I was looking for something that gives us an overall idea and this video did the job !!!
excellent over view for ETL learners. I've watched similar videos before this and no one explained it as good, fast, and clear as you do. Thank you so much.
Glad it was helpful!
In a span of time I got a descriptive knowledge about ETL .Thank you.
This is the best tutorial given by you because nobody has so far touched it
What a Great and simple explanation - finally - after so many videos that are so complicated and with youtubers showing their faces and talking talking talking and they don't go to the poin.
This was on the point !! Directly and Well Explained!! Great!!
Felt like I got 20 pages worth of information in just 8 mins, thank you so much!
Great to hear!
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.
Man, this was BEAUTIFUL!!! A real-world example makes all the difference!!
The best explanation of OLTP and OLAP I have watched in YT so far. Thanks a lot, bro
I really like your explanation very clear and with examples. Thank you so much men!!!!!! I almost forget your english speaking is so good thank you also for that, because is an extra effort and that give you extra points also!!!!
One of the best explained videos on ETL so far. Looking forward to learning more from your videos
The best explanation on data warehouse. Thx!
Simple crisp and clear. loved it!
I just wanted to say that I was really impressed by the way you explained this. Keep it up.
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.
This is the best video I've seen so far. Great content for beginners.
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.
