A variety of examples of business monitoring and performance analysis are explored, showing how we used these to satisfy requirements from a range of users in insurance companies we have worked with in recent years.

A Sense of Perspective: How to use a Star Schema Data Warehouse to see any historical view you want.

(SeUGi 20 - Paris, France, June 2002)

Covering the reasons why history is needed in a data warehouse, and the different Time perspectives that may be required to support the business need for a "true" presentation of past data, this paper highlights some of the crucial techniques involved in building and querying a fully historical data store using extended Star Schema designs. A potential "ultimate star schema" with all possible viewpoints available is also discussed.
