[@rustamgonezhukov8133]

I never could understand the differences from the articles, it's always seemed overcomplicated, but after this video it became clear. You definitely have a talent in explanation of complicated thing with simple words. thanks!

One of the best videos - explaining the isolation levels. Just awesome !!

[@robertkorth605]

The simplest, shortest and clearest presentation of the topic i have found so far. Thank you.

[@ivantang5795]

Isolation levels and the problems they solve so so so simply explained. I wished I can give this video a hundred thumbs up. I couldn't understand the different scenarios that the various isolation levels prevent as explained in "Database System Concepts" by Abraham Silberschatz. After watching this video I totally get it.

Thank you for the explanation it's very useful. I was wondering if you meant Lost update in the example with Non-repeatable read instead? timestamp was 5:43

Awesome explanation!

[@LokeshKumar7]

To prevent the non repeatable read it acquired the lock on the row which is read and no one can update the same row until transaction is complete, correct?

[@crazymotherfucker89]

Very well explained

[@arungowda]

Brings the question : how are isolation levels different from database locks?
