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!
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
Can you please do a video on 1. two serializable transactions executing concurrently 2. A serializable and non-serializable transaction executing concurrently
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?
