Oracle Tips

The Data Warehouse Development Life Cycle

Economic Feasibility

DATA WAREHOUSES AND ROI 

* Application area differences--There are differences among data warehouse ROIs based on the type of organization that develops the data warehouse. Data warehouses designed to support engineering and operations tend to have the highest ROI. This makes sense because, historically, manufacturing organizations have been among the first to embrace data warehousing. The IDC study also shows that European companies developing data warehouses lag behind American companies by a 100 percent margin of ROI, with European companies averaging 340 percent ROI and American companies averaging 440 percent ROI.
The overall finding in the IDC study showed that data warehouses are popular primarily because of the fast payback period for the dollar investment. Interestingly, the payback period most likely will become even shorter as data warehouse developers create more intelligent queries against their data and become more adept at locating and analyzing trend information.


This is an excerpt from "High Performance Data Warehousing". To learn more about Oracle, try "Oracle Tuning: The Definitive Reference", by Donald K. Burleson.  You can buy it direct from the publisher at 30% off here:
