1 - About

In a 1958 article, IBM researcher Hans Peter Luhn used the term business intelligence. He defined intelligence as “the ability to apprehend the interrelationships of presented facts in such a way as to guide action towards a desired goal.”

In 1989 Howard Dresner (later a Gartner Group analyst) proposed BI as an umbrella term to describe “concepts and methods to improve business decision making by using fact-based support systems.” It was not until the late 1990s that this usage was widespread.

Over 15 years ago, BI was called decision support
