Business Intelligence refers to a set of methods and
techniques that are used by organizations for tactical and strategic decision
making. It leverages technologies that focus on counts, statistics and business
objectives to improve business performance.
A Data Warehouse (DW) is simply a consolidation of data from
a variety of sources that is designed to support strategic and tactical
decision making. Its main purpose is to
provide a coherent picture of the business at a point in time. Using various Data Warehousing toolsets,
users are able to run online queries and 'mine" their data.
