ToM Focal – Introduction to Focal implementation
The Focal pattern was implemented the first time as a Data Warehouse in the year 1998. That Data Warehouse is still running on the same base code today. Over the years the Focal pattern has been used and improved on many different implementations.
Today at Top of Minds Focal company, we work with the continuation of the Focal Framework and teaches others how to use it.
This document gives an introduction to how a Focal Data Warehouse works, both from a modelling perspective, but as well from an implementation perspective. All examples are simplified for ease of understanding.
