Understand (or teach) the Basics of SQL

In the last few months, we've shared some infographics that explain basic technologies and terminologies. Given many of our readers are technology professionals who are already well-versed in this information, why would we share this? First, not every independent IT contractor knows everything, meaning some of these infographics could be great refreshers. Secondly, while on contract, you are sometimes required to train internal employees how to do things. These infographics can prove to be very helpful tools.

In our most recent find, this handy image from Udemy explains the basics of SQL, a language that accesses corporate databases around the world. Feel free to share it!
