The second edition of this best-seller is revised and updated. It
delivers a reader-friendly explanation of the relational model and its
importance to database designers and builders. Clear explanations make
use of examples rather than equations, and show how an understanding of
the relational model can lead to making a database faster and flexible.
Topics covered include: nulls, primary and foreign keys, joins,
relationships, domains, indexing, and many others. The authors manage to
shed light on this tricky subject with substance and style.
