Next week, on Aug 18, Andy Leonard will be starting the first part of his webinar series, which focuses on a discussion on data warehouse basics.  Andy will discuss what a data warehouse is and why you’ll get somewhat different answers depending on who you ask.  He will be looking at the beginning of this, and talk about the two schools of thoughts.

As you might know Ralph Kimball championed one school which says that all data marts in an enterprise feed into the data warehouse.  Bill Immon on the other hand believes that there is the notion of a central data warehouse that generates these data marts.  As a result, there are differences in the database schemas as well.  Kimball champions star schemas, and Immon likes the 3rd normal form.  More on this in Andy’s short video below.
