This is an online SQL environment. It provides tutorials to learners, which they can interact with, execute their own SQL, and obtain automatic feedback on the quality of that SQL.

Anyone is free to use the environment. Registration is used to support users returning to the site to continue from where they left off. Please be accurate in registration details, thus allowing me to separate real University students from independent users.
