I do quite like SQL, but not so up on the others. I'm more into Python.

I've tinkered with some very simple SQL and is certainly one to delve a little deeper into. Was useful in my previous job.

I have worked a lot with Oracle databases before and did some SQL server recently. I like with SQL that you can just run it can see the results immediately.

Greetings. I wish you good luck. I'm sure you'll do well with the book. I'm learning more and more about Python every day.
