Typical BI architecture for structured data centers on a data warehouse. The data are
extracted from operational systems and distributed using Internet browser technologies (Figure
5). The specific data needed for BI are downloaded to a data mart used by planners and
executives. Outputs are acquired from routine push of data from the data mart and from response
to inquiries from Web users and OLAP analysts. The outputs can take several forms including
exception reports, routine reports, and responses to specific request. The outputs are sent
whenever parameters are outside pre-specified bounds.
