Logical Data Warehouse
A logical data warehouse (LDW) is usually defined as an architecture layer that rests on top of data warehouse persisted data and allows viewing data without transformation or movement. A logical data warehouse set-up allows analysts and other business users to access fresh data without formatting and eliminates the need to transform and consolidate data from disparate sources in order to view it.
Although a "logical data warehouse" may seem like a redundant term, it essentially provides a more holistic view of an organization's data at any point of time regardless of where that data may reside.
