Grawlix (Database layout help needed)

Hi,
I've been working on a sort of online game maker as a project for school this past semester. It's sort of evolved from previous attempts at making either games or game engines, and I never got very far, always focusing on details rather than completing the whole. The project was a bit too much from the start, but we did manage to get something complete by the end of the semester. It's a bit messy and needs many changes?
Please help.
Thanks!

I didn't find the right solution from the Internet.
