One of the first commands you want to know is the command that lets you see all databases (if any) available in this instance of MySQL
The Command for this is:
$ show databases
Here I see what a brand new instance of MySQL looks like with no User Databases created yet
The objects (Databases) that are here are part of the MySQL system and for the most part you will not do anything to them in this class
Notice the semicolon; we are in a code interpreter here so syntax rules apply
