Data Warehouse
Guide to Data Warehousing and Business Intelligence
A Data Warehouse (DW) is simply an integrated consolidation of data from a variety of sources that is specially designed to support strategic and tactical decision making.
The main objective of a Data Warehouse is to provide an integrated environment and coherent picture of the business at a point in time.
The Data Warehouse can be the source of data for one or more Data Marts.
Data from the Data Warehouse can be made available to decision makers via a variety of "front-end" application systems and Data Warehousing tools such as OLAP tools for online analytics and Data Mining tools.
