These techniques did not however require the computing power which is required today (Andronie & Crisan, 2010). The changing applications in business have therefore demanded the use of Business Intelligence (BI). Business Intelligence is a field that provides software tools that are tailor made for end-business users to deliver business insights at the right time during decision making processes (Folorunso et al, 2010).

As one of the BI techniques, the first data mining model was derived from statistical methods (classical techniques) including cluster and statistical analysis which are used even today.
