How to study the database structure of the table and the purpose?

Welcome colleagues! Again ask for help to the community of Toaster and again with the amateurish question from the series "You studied it for 10 years, help me to understand it one day".

I need urgently to learn to work with databases. Not in depth, for the most part superficially, using PMA. Gentleman's set Denwer installed, open a PMA learned. Even imported my own table. Now I need to figure out what it is, what is, and so on. And just to make test requests.

Tell me what articles, lessons and so on, where to start, so as soon as possible to be able to perform the above. The pros in karma and gratitude you provided.
