After initializing phpMyAdmin on my server, I created a test database in the GUI platform. I realized that I had then received a notification in the phpMyAdmin browser that I needed to set up an initial configuration, in any database, and to "click here" to do it. So, I clicked the link and the database I was in was populated with a bunch of tables beginning with pma, which I believe represents the control user? I'm not really sure what this means or why every table begins with "pma_".
So, since the database I was in is now my "configuration storage" database, I renamed it and am just leaving it as is; no extra tables or data other than what the automatic configuration executed when I clicked the button that I mentioned previously.
The wiki for phpMyAdmin explains the configuration storage setup, but I don't believe I need to do that because the button that I had clicked in the alert space of the GUI did that for me.
So, what's the point of this database, what is pivotal information that I should know about it, and is it safe for me to just leave it alone and move on about my business? Thank you.
NOTE: I've used MySQL and phpMyAdmin before but it was under my university's environment and provided database; I never had to set up one of my own or do this confutation step.
