The term “Big Data” has many definitions, most recently the term is used to describe business intelligence use cases which allow organizations to better understand their customers. In the past the high cost of data warehousing limited the scope of business analytics — sifting through very large data sets was cost prohibitive. Users, unable to afford these costs, were unable to make business advantage of the information — the data often was not even collected. Recently the use of tools such as Hadoop (MapReduce) changes the cost equation enabling organizations to learn more from the information that’s available to them. The emergence of Big Data tools has created a new category of business intelligence applications and holds exciting promise for the future.
