The Modern Data Warehouse (MDW) is where the consolidated and governed version of corporate data is presented to the business users. This way, users can access, understand, and trust the data, knowing it has been groomed and validated by the BI team.
In the MDW, business users can access, understand, and trust all the data they need. This is different from a traditional approach, since the goal is to support self-service. The Modern Data Warehouse includes additional tables and fields, empowering self-service users with richer data, and reducing long term maintenance.
