Description:
“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.

描述:
這本書將滿足那些想要從不同角度了解Oracle官方文件的人。它將涵蓋數據倉庫的所有重要方面,並提供必要的示例,使閱讀變得生動有趣。- Tim Donar,作者和企業數據倉庫系統架構師
調整數據倉庫數據庫主要關注大型交易,通常需要通過服務器、網絡和互聯網環境來傳遞大量信息,不斷地來回傳輸!數據倉庫的最終目標是從歷史和存檔數據中生成有意義和有用的報告。關鍵是使報告在可接受的時間範圍內打印出來。
數據模型包含表和表之間的關係。調整數據模型涉及到規範化和反規範化。根據應用程序的不同,如OLTP或數據倉庫,需要採用不同的方法。不適當的數據庫設計可能使SQL代碼無法調整。糟糕的數據建模對數據庫性能有最深遠的影響,因為所有的SQL代碼都是從數據模型構建的。
