In the first half of this article, published in the April issue, we saw that drilling across was the defining act of the integrated enterprise data warehouse (EDW).

The dimension manager is a centralized authority who builds and distributes a conformed dimension to the rest of the enterprise, and the fact provider is the client who receives and utilizes the conformed dimension, almost always while managing one or more fact tables within a subject area.
We are now ready to roll up our sleeves and describe exactly what the dimension manager and fact provider do.
