There are some that argue the best approach is to start with data marts, department by department, then merge them together to form a data warehouse- this is more in line with Kimballs approach. Now, Bill Inmon is an advocate of the Data warehouse. Here's one of his articles, which contains the following quote that makes it clear what he thinks about the idea: You can catch all the minnows in the ocean and stack them together and they still do not make a whale, Bill Inmon, January 8, 1998.
At night, the nocturnal slow loris will slowly climb around in the trees searching for food. Because of a slow lorises location (habitat), it has access to many fruits, plant matter, and insects including ants and termites. Slow lorises also eat plants that produce nectar, the gum (high glucose sap from trees) and even bird eggs. Their diet makes them primary and secondary consumers.

In order for cells to survive, they require nutrients in the form of glucose and minerals plus oxygen. Additionally, they need to dispose of waste products. Cells also rely on their organelles and diffusion for survival. Without oxygen, minerals and the removal of waste products, cells do not survive. In animals, blood delivers the necessary nutrients and oxygen as well as carries away waste. These processes rely on a mechanism called diffusion, which allows substances to pass from one side of the cell wall to the other.
