(please excuse my typing. i have one hand to use ATM) yup. we bet super hard on sql too. Its fantastic if you know what you're doing. We ca import arbitrary data and expose it as normal tables to our customers for analysis/transform/export along with having a silod access controlled place for them to see just their data. sql is a great technology, and is extremely flexible.

I love it. If you're looking to learn it and fundamentals, check out Jennifer Widom's course from Harvard. I can safely credit her w/ my career.
