Oracle Data Warehouse Tuning for 10g

by Gavin Powell

“This book should satisfy those who want a different perspective than the official Oracle documentation. It will cover all important aspects of a data warehouse while giving the necessary examples to make the reading a lively experience.”
- Tim Donar, Author and Systems Architect
for Enterprise Data Warehouses

Tuning a data warehouse database focuses on large
transactions, mostly requiring what is known as throughput. Throughput is the passing of large amounts of information through a server, network
and Internet environment, backwards and forwards, constantly! The ultimate objective of a data warehouse is the production of meaningful and useful reporting, from historical and archived data. The trick is to make the reports print within an acceptable time frame.

A data model contains tables and relationships between tables. Tuning a data model involves Normalization and Denormalization. Different approaches are required depending on the application, such as OLTP or a Data Warehouse. Inappropriate database design can make SQL code impossible to tune. Poor data modeling can have a most profound effect on database performance since all SQL code is constructed from the data model.

About the author

Mike McCallister is devoted to the idea that technology need not be feared, and can be mastered by anyone. After all, he grew up in the days when computers filled entire rooms, and spent 13 years as a civil service clerk doing nothing more technical than recording WordPerfect macros.

He is devoted to making computing easier for the full spectrum of user levels and experience. As a technical writing consultant, freelance computer magazine writer, and book author, he understands that ordinary people can and should make the most of their tools.

Besides Linux and open source software, interests include tools for communicating via the Web (blogs, social networks, wikis, and the like) and bridging the digital divide.

McCallister has been running Linux as his primary day-to-day desktop operating system since 1999, but he also documents software for a variety of platforms as the Document Architect at PKWARE, Inc.

He writes a technology-oriented blog, Notes from the Metaverse. His technology stories have been published in places like:

LinuxJournal.com

LinuxWorld

Java Developer's Journal

SearchEnterpriseLinux.com

He is a compulsive joiner. Among the relevant groups: Senior Member of the Society for Technical Communication, and immediate past president of the Wisconsin chapter; Web414, Milwaukee's Web Community; and the National Writers Union, UAW Local 1981.

He absolutely loves going to BarCamps and BarCamp-style events, especially BarCampMilwaukee. Occasionally, you'll also find him at the Milwaukee Linux Users Group

When he's not staring at computer screens (which he admittedly finds strangely alluring), you'll often find him trying to make the world a better place. Or reading, watching a baseball game or other sporting event (live or on TV), hanging out with the grandkids and walking around urban landscapes. "
