Relational databases hold data, left? They indeed do, but to think of a

database as nothing more than a container for data is to miss out on the

profound power that underlies relational technology. A far more powerful

way of thinking lies in relational technology's foundation in the

mathematical disciplines of logic and set theory. Databases contain

truths or propositions describing some area of interest such as a

business. Those truths are organized into sets. Operations from logic

and set theory can be applied to existing sets of truths to derive new

sets of truths. Applied Mathematics for Database Professionals

introduces you to this way of thinking, to the logic and set theory that

underlies relational database technology. All this may sound abstract

now, but there are profound benefits from the deeper understanding

you'll gain from this book. You'll learn to

- Become a better database designer. You'll make fewer mistakes, and

your designs will be more flexible in response to changing data needs.

- Use the expressive power of mathematics to precisely specify designs

and business rules.

- Communicate effectively about design using the universal language of

mathematics.

- Develop and write complex SQL statements with confidence.

- Avoid pitfalls and problems from common relational bugaboos such as

null values and duplicate rows. The math that you learn in this book

will put you above the level of understanding of most database

professionals today. You'll better understand the technology and be able

to apply it more effectively. You'll avoid data anomalies like

redundancy and inconsistency. Understanding what's in this book will

take your mastery of relational technology to heights you may not have

thought possible. This book is reviewed and endorsed by C. J. Date and

features a foreword by the same.
