Nikola Ilic gives us a primer on Kimball-style fact and dimensional modeling:
Before we come up to explain why dimensional modelling is named like that – dimensional, let’s first take a brief tour through some history lessons. In 1996, a man called Ralph Kimball published a book “The Data Warehouse Toolkit”, which is still considered a dimensional modelling “Bible”. In his book, Kimball introduced a completely new approach to modelling data for analytical workloads, the so-called “bottom-up” approach. The focus is on identifying key business processes within the organization and modelling these first, before introducing additional business processes.
This is a really good overview of the topic, though I’m saddened that “dimensional bus matrix” didn’t make the cut of things to discuss. Mostly because I like the name “dimensional bus matrix.”
