{{Note[[Image:KPI.png|left|Write an introduction about 75px]] Business intelligence (BI here) is a set of theories, methodologies, architectures, and about BI in mine actiontechnologies that transform raw data into meaningful and useful information [http://en.wikipedia.org/wiki/Business_intelligence]. While operational systems - such as {{IMSMANG}}and many others - are designed and optimised for data entry and updates, a BI system is read-only and designed for '''analysing''' and '''visualising''' data. The overall objective is to inform the decision making process, thus allow for evidence-based decision making. An important criterion of the underlying data is its '''quality''' - meaningful analysis can only be achieved if the input data is accurate, complete, and of known quality.
