I just came across your channel and you have gained a subscriber. The short form videos and explicit explanation is makes it extremely easy to understand the subject. My company has paid thousands for training instructors but for me it is not my preferred approach to learning, I often feel frustrated. This just works and it is in-depth. I wish you all the best with your videos, I'll be watching.

The only remark is that we MUST NOT create an index for EVERY field we use in the queries, because a big amount of indexes slows down the insert/update operations, because indexes must be rebuilt after.
