This book is intended to novice database designers, and SOHO users of Access and other consumer oriented database products. Still most of the material can still be of use to the professional database designer that uses Enterprise level databases like Oracle, MSSQL and other such advanced system. The book focus on good design methodologies in a trial and error aproach that is illustrative of the way most of us would create a database if we had not had any training or previous courses on the topic, like is so many times the case in academic and non IT curricula, like professors, CPAs, and other professionals that have not had any training on the topic of Database Design.
