Expert Oracle Exadata
By Kerry Osborne , Randy Johnson , Tanel Põder
Throughout history, advances in technology have come
in spurts. A single great idea can often spur rapid change as the idea takes
hold and is propagated, often in totally unexpected directions. Exadata
embodies such a change in how we think about and manage relational databases.
The key change lies in the concept of offloading SQL processing to the storage
layer. That concept is a huge win, and its implementation in the form of
Exadata is truly a game changer.
Expert Oracle Exadata will give you a look under the
covers at how the combination of hardware and software that comprise Exadata
actually work. Authors Kerry Osborne, Randy Johnson, and Tanel Põder share
their real-world experience, gained through multiple Exadata implementations
with the goal of opening up the internals of the Exadata platform. This book is
intended for readers who want to understand what makes the platform tick and
for whom—"how" it does what it is does is as important as what it
does. By being exposed to the features that are unique to Exadata, you will
gain an understanding of the mechanics that will allow you to fully benefit
from the advantages that the platform provides.
