EDW Architecture to Manage the Evolving Business

Enterprise Data Warehouse are a mirror of the business.  They are in constant state of flux.  We have a choice, manage the change or cease to be meaningful or useful. One does not gain the status of flexible in a warehouse by chance, it must be designed into the fabric of the system. This presentation discusses one approach that has proven to be both flexible and simple focus on techniques and methods that allow the EDW to evolve over time and not simply become last  years solution.
