Improve the performance of relational databases with indexes designed
for today's hardware Over the last few years, hardware and softwar
e have advanced beyond all recognition, so it's hardly surprising
that relational database performance now receives much less attention.
Unfortunately, the reality is that the improved hardware hasn't kept
pace with the ever-increasing quantity of data processed today. Althou
gh disk packing densities have increased enormously, making storage
costs extremely low and sequential read very fast, random reads are
still painfully slow. Many of the old design recommendations are
therefore no longer valid—the optimal point of indexing has
come a long way. Consequently many of the old problems haven't actuall
y gone away—they have simply changed their appearance.
This book provides an easy but effective approach to the design of
indexes and tables. Using lots of examples and case studies, the
authors describe how the DB2, Oracle, and SQL Server optimizers determ
ine how to access data, and how CPU and response times for the resulti
ng access paths can be quickly estimated. This enables comparisons to
be made of the various designs, and helps you choose available choices
for the most appropriate design. This book is intended for
anyone who wants to understand the issues of SQL performance or how
to design tables and indexes effectively. With this title, readers
with many years of experience of relational systems will be able to
better grasp the implications that have been brought into play by the
introduction of new hardware.
Unpack it, and enjoy it!
