Description: In order to be effective, data warehouse developers need to show tangible results quickly. At the same time, in order to build a data warehouse properly, you need a data model. And everyone knows that data models take huge amounts of time to build. How then can you say in the same breath that a data model is needed in order to build a data warehouse and that a data warehouse should be built quickly? Aren’t those two statements completely contradictory?
The answer is — not at all. Both statements are true and both statements do not contradict each other if you know what the truth is and understand the dynamics that are at work.
