Business Intelligence can be defined as "deriving Information from Data".
Current Best Practice includes tailored User Portals, Dashboards and Key Performance Indicators,('KPIs').
For a Business Intelligence System, an enterprise needs to manage the data from End-to-End.
This requires quality assurance from the Source to the Target.
It is becoming more important for a 'Data Steward' to assume ownership of data at each stage in its processing.
