Distributed Data Warehousing Using Web Technology

What is a “data
warehouse?” It’s a database that’s structured to support
business decision making. A data warehouse organizes, analyzes, and
synthesizes huge amounts of raw data—so that it’s intelligible
and useful to employees. Until recently, all that data would be stored
in centralized, monolithic storage media. It was cumbersome to manage,
slow to operate, and expensive to maintain.

Internet technology
has changed all that forever! In this insightful book, managers and
information technology professionals get a clear-eyed overview of what’s
required to set up and use distributed data warehouses—which utilize
multiple computers (networked together via Internet technology) to store
and access data as needed. The book takes a look at:

• Basic functions and benefits of a distributed data warehouse and what's required to set one up
  
• Many of the complex technical issues involved, such as placement of functions and data, web-enabled computing technologies, object technologies, and more
  
• The full spectrum of what a data warehouse can deliver—and how to exploit it
  
• How to present and justify a business case for creating a data warehouse
