Relational databases hold data, right? 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.
