Oracle Data Warehouse Tuning for 10g

"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.This book takes users beyond basics to critical issues in running most efficient data warehouse applications.

It illustrates how to keep data going in and out in the most productive way possible.

The focus is placed on Data Warehouse performance tuning.
