Hello. I'm developping a project about the decision tree in Java. My project idea is about animals, but it's gonna be a big database and i don't have too much time to complete. So my question is: Can anyone help me to found a complete database about animals or about anything related to a decision tree project(maybe about fictional character, etc..). (Note: the database should be in sql or oracle). Thanks in advance.

If it is impossible to find a complete database, a link to a website that gives all informations about all animals will be helpful.
