My introduction to Data Warehousing was a water cooler discussion with a colleague just returned from a Data Warehousing workshop. The main topic of that discussion was the long development time required by data warehousing projects and how foolish it was start any project where the first "deliverable" to a business user was planned for three years hence.

With the approach that Ms. Moeller presents in this book, however, data warehouse projects are made eminently manageable by planning a series of major deliverables spaced 3-6 months (not YEARS) apart - at a fraction of the cost of a full-blown "Data Warehouse."
