Description: Functional Data warehouse is a warehouse that draws data from nearby operational systems. Each functional warehouse serves a distinct and separate group (such as a division), functional area (such as manufacturing), geographic unit, or product marketing group. Today's business environment is very data driven and more companies are hoping to create competitive advantage over other business organization competitors by creating a system whereby they can assess the current status of their operations any at any given moment and at the same time, they can also analyze trends and patterns within the company operation and its relation to the trends and patterns of the industry in a truly up-to-date fashion.
