What is an enterprise data warehouse?
“an enterprise data warehouse (EDW), is a system used for reporting and data analysis, and is considered a core component of business intelligence. (E)DWs are central repositories of integrated data from one or more disparate sources. They store current and historical data in one single place that are used for creating analytical reports for workers throughout the enterprise.” - wikipedia
One of the biggest problems with Enterprise Data Warehouses (EDWs) is that they are being used in ways that were not intended. This is increasing the cost of them for many organisations.
