This session will describe a large data warehouse that we built with the medical data for a large hospital. The warehouse has a Kimball architecture with 200+ dimensions and 100+ facts. The primary input source is from Epic Clarity. We'll describe the project and give a flavor of the data model. We'll discuss some of what went right and wrong about the project and take questions from the audience.
