Introduction
This paper is about building powerful data marts that require minimal administration and are simple to change. This may seem like an impossible goal to anyone who has been involved in the usual complexity of these projects, but there are a number of simple, practical concepts and methodologies that have been employed and tested over many years of successful data warehouse implementations that are repeatable and are easy to understand. These techniques have been used in projects around the world by the author both personally and as baked into software and methodology.
