Database Design for Mere Mortals: A Hands-On Guide to Relational Database Design. Addison Wesley, 1997.
Hernandex, Michael J.
If you'd like to learn how to create & design a database, then this is the book you need. The "mere mortals" part in the title is not a joke - this is a book written for normal people who want to learn a new skill, not tech-heads.
