SQL Query Optimization: Understanding Key Principle (opens in new tab)

Very cool, thanks.

I totally agree with the fact that understanding the problem of slow application is a first what you need to do.

Very nice research; I thought I knew a lot of things regarding SQL. Little did I know there is a lot to learn. Being in the tech stack is quite rewarding as long as you commit to learning something new every day. Also, I agree that we should optimize our code and our database to make our application function fast.
