Database?! I had no idea what I was getting into with this one. Turns out, though, I like it! There is some serious power in the back-end development side of the industry and I do believe that is the field I want to put more of my effort into. Just remember: SELECT, FROM, WHERE, ORDER BY!

This language remains less than glamorous as it is mainly used for data retrieval so far, but I can see the potential.

Unions seemed pretty important, too, but they can apparently have performance issues. Hey, though, they work! Work first, optimization second, right? Maybe, like I said, just getting started! A few more organized exercises. Code:

The last thing I worked on was the Guitar Shop selection. Code:
