MySQL
I’ve been familiar with MySQL for a few years but going back over it again in this unit has been very helpful. Much like the Linux shell commands, I learned some very basic commands and only used what I needed to for the task at hand. If I hit a situation where I needed to do something I didn’t know how to do, I’d research, find what I needed and implement it and troubleshoot afterwords. Going back and picking up some more concepts and commands in MySQL gives me more tools in my box and a better core understanding of the base concepts in relational databases. I’ve never had to use a right or left join in a database before, but now that I know about them, I’m sure there will be situations where I find them useful. In addition, it’s always good to have refreshers on these things as well. I don’t work directly with MySQL queries every day so getting in there and playing with the code is always a good way to brush up on neglected skills.
