Database design/relationship basics book

Does anyone have some recommendations for database books. This is something that I want to get better versed in as I have gotten along by visualizing the database and its relationship for small projects, but I think I need a better base and more knowledge. Recommendations can before both MySQL specific, a query book and a database in general, please I have done database designs for small projects by trial and error and extending original schemas, I would like to learn to do it right the first time. So any suggestions will help. thanks in advance dan __________________________________________________ Do You Yahoo!? Find the one for you at Yahoo! Personals http://personals.yahoo.com
