One of today's biggest trends in information systems is Business Intelligence (BI). But while everybody talks about the term few people really grasp its contents. An illustrating example is a quote from an IBM Account Manager: "By data warehousing we at IBM mean whatever the customer thinks it means." (S. Few, 2006) In fact Business Intelligence covers a wide range of architectures, tools, databases, applications and methodologies supporting decision-making within an organization. These parts can be roughly grouped into two layers. The provisioning layer, providing useful data and the consumption layer which covers how to extract information and knowledge from this data.
