As vice president of Business Intelligence in Oracle’s Technology Business Unit, he is recognized world-wide for his work in business intelligence and data warehousing. His papers regarding business intelligence and computer and software technology have appeared in publications such as
President & CEO Magazine
,
Database Trends and
Applications
, and The Data Warehousing Institute’s publications. He has also coauthored the books

(O’Reilly),
Professional
Oracle Programming
(WROX), and
Oracle Data Warehousing and Business Intelligence Solutions
(Wiley).

Jonathan Stern
used more than 13 years of IT experience in contributing to the original edition of this book. His background included senior positions in consulting, systems architecture, and technical sales. Especially useful in his early work on this book was his in-depth experience with the Oracle database across all major open systems’ hardware and operating systems, covering tuning, scaling, parallelism, Oracle Parallel Server, high availability, data warehousing, and OLTP. He authored numerous papers and presented at internal and external conferences on topics such as scaling with Oracle’s dynamic parallelism and the role of reorganizing segments in an Oracle database.

Colophon

The animals on the cover of
Oracle Essentials: Oracle Database 11g
are cicadas.

There are about 1,500 species of cicada. In general, cicadas are large insects with long thin wings that are perched above an inch-long abdomen. Their heads are also large and contain three eyes and a piercing and sucking mechanism with which to extrude sap from trees. Cicadas are known for their characteristic shrill buzz, which is actually the male’s mating song, one of the loudest known insect noises.

Cicadas emerge from the ground in the spring or summer, molt, then shed their skin in the form of a shell. They stay near trees and plants, where they live for four to six weeks with the sole purpose of mating. The adult insects then die, and their young hatch and burrow into the ground. They attach to tree roots and feed off the sap for 4 to 17 years, after which time they emerge and continue the mating cycle. Cicadas have one of the longest life spans of any insect; the most common species is the periodical cicada, which lives underground for 13 to 17 years.

The cover image is an original 19th-century engraving from
Cuvier’s Animals
. The cover font is Adobe ITC Garamond. The text font is Linotype Birka; the heading font is Adobe Myriad Condensed; and the code font is LucasFont’s TheSans Mono Condensed.
