Great! That was the last exercise in the entire course. Congratulations!

You should now be able to work with indexes in SQL. You know how indexes work behind the scenes, when they are created automatically, and what price you pay for creating too many of them. You also learned some advanced concepts, such as partial indexes and indexed expressions.

If you liked the course, please leave a review for future students. And if you feel like learning more, take a look at all the other courses we offer.

We hope to see you again!
