Business intelligence has come a long way and has transformed into a broader and deeper space as a key ingredient for aiding and executing business strategies. Intelligence or understanding of the business is achieved through collecting key information about core business actives such as marketing, sales, services etc. and analyzing behavior of customers, staff, suppliers, so that right actions can be taken at the right time. BI system would involve continually collecting (data warehousing) information about the organizational activities and then further organizing it to facilitate analysis, reporting, data mining and catering to more diverse analysis needs.
