I wish I had watched this long time ago. Even though I had used Oracle for so many years, I didn't pay attention to this kind of details related to performance tuning. Thank you Chris! I will dedicate my time to go through all your videos.

This is the best way to explain the concept in a very simple terms. I was like visualising the things when you are explaining. Thanks for such a great content. Really appreciate your efforts.

can you explain how come the execution plan for same query is different based on data. for one case it shows full table scan and for another case it shows index range scan.

I was about to post a comment on a major flaw with the analogy, but I just heard your closing teaser for the next installment, so you've probably got it covered and I just need to be patient. ;D
