Why Most Business Intelligence Tools Fail the 'Hadoop Test' by Sarah Gerweck on +Information Management - BI is still largely using 17th-century statistical techniques: counts, sums, averages and extrema. At most, we might use techniques that were used by Gauss and Galton in the 19th century.
Very interesting blog. I have to agree with her that BI is ok for lightweight reports but to do proper statistics in the past has needed something specialist. If BI can adapt to enable use of Hadoop like structures and more statistics type reports/functions it will continue to be successful.
