Book excerpt: Relational database systems enable huge transaction processing applications for the largest enterprises worldwide. This textbook on relational database management, for a first graduate or advanced undergraduate course, emphasizes the skills and knowledge needed to develop these applications. The author draws upon four decades of experience, starting as employee #12 at Oracle, and later working for an organization that built complex database applications, and finally as the Enterprise Data Architect for a large organization. That experience has shown him both what is needed to be successful in developing such applications, and what graduate students typically don't learn from courses on the subject. This book gives emphasis to skills in SQL language, data modeling, normalization and performance tuning. The approach taken is to use "just enough math," presenting enough math so that the concepts are properly understood, but avoiding gratuitous proofs that are not of practical use, that commonly are found in database textbooks.
