Getting Down With SQL

I looked over the Wikipedia page about Normalization and I think I understand it. I don't fully understand 1st, 2nd, and 3rd Normal Form because a lot of terms I do not know are used but I think I know enough to start working with SQL. I started by recreating the tables made in the Manga and I think I finally know how to operate the basics after coming across problems but fortunately you could answer them(like not using periods in my code). Tomorrow I will finish up the tables and try different operations like updating the data.
