The corporate data model is the secret to being able to build the data warehouse iteratively. The first development effort uses one part of the corporate data model. The next development effort uses another part of the corporate data model. The next yet another part of the corporate data model...

This chapter discusses a method for developing dimensional data warehouses based on an enterprise data model represented in entity relationship form. This is a more structured approach to data warehousing design and ensures the structure of the warehouse reflects the underlying structure of the data. ...
This model, based on the AdventureWorks data warehouse, does not use particularly complex data. Therefore, there are not many splits in the ARTXP tree. However, even this relatively simple model illustrates three different kinds of sp...
