Challenged by w3schools!:
The bulk of my knowledge on the mySQL database language came from the tutorials on w3schools. The tutorial was fantastic, and in detail went through all the key words used to generate the queries to create the databases, as well as had great hands on opportuinities to practice, by allowing the user to try running segments of code, to see what effect they had on the database. After completion of the tutorial, I easily aced the w3schools quiz.
