Data Warehouse and Business Intelligence in Order
The key contrast is that both data warehouses and BI are two totally different constructs. The first refers to systems that are used for storing data for archival, analysis, and security purposes. The second refers to variety of software applications that are used to analyze the data that the organization has accumulated. Forrester Research, for instance, distinguishes BI by defining them as " a set of methodologies, processes, architectures, and technologies that transform raw data into meaningful and useful information used to enable more effective strategic, tactical, and operational insights and decision-making." (Evelson, 2008).
