All of today’s mainstream database products support the SQL
language, and relational theory is what SQL is supposed to be based
on. But are those products truly relational? Sadly, the answer is no.
This book shows you what a real relational product would be like, and
how and why it would be so much better than what’s currently
available. With this unique book, you will: Learn how to see database
systems as programming systems Get a careful, precise, and detailed
definition of the relational model Explore a detailed analysis of SQL
from a relational point of view There are literally hundreds of books
on relational theory or the SQL language or both. But this one is
different. First, nobody is more qualified than Chris Date to write
such a book. He and Ted Codd, inventor of the relational model, were
colleagues for many years, and Chris’s involvement with the
technology goes back to the time of Codd’s first papers in 1969 and
1970. Second, most books try to use SQL as a vehicle for teaching
relational theory, but this book deliberately takes the opposite
approach. Its primary aim is to teach relational theory as such. Then
it uses that theory as a vehicle for teaching SQL, showing in
particular how that theory can help with the practical problem of
using SQL correctly and productively. Any computer professional who
wants to understand what relational systems are all about can benefit
from this book. No prior knowledge of databases is assumed.
