Business intelligence (BI) is a runaway locomotive that keeps picking up speed in terms of enterprise interest, adoption, and spending levels. The result: There are now more than 80 vendors in the segment. Their architectures and user interfaces vary, but they support similar use cases. This report tells application development and delivery (AD&D) pros working on BI initiatives how to decide which vendors belong on their shortlists of BI platforms. This is an update of a previously published report; Forrester reviews and updates it periodically for continued relevance and accuracy.
