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.
Hands are broad with an opposable thumb. Males and females are similar in appearance. Pygmy slow loris (or lesser slow loris) are nocturnal and arboreal. They seem to live solitary or in small family groups consisting of an adult male, an adult female and one or two generations of offspring. To remain inconspicuous, vocal exchanges are limited, and communication is primarily by olfactoric means, i.e. urine marking.
