  Steve Jobs, one of the greatest visionaries of our time was quoted in 1996
saying "a lot of times, people do not know what they want until you show it to
them" [38] indicating he advocated products to be developed based on human
intuition rather than research. With the advancements of mobile devices, social
networks and the Internet of Things, enormous amounts of complex data, both
structured and unstructured are being captured in hope to allow organizations
to make better business decisions as data is now vital for an organizations
success. These enormous amounts of data are referred to as Big Data, which
enables a competitive advantage over rivals when processed and analyzed
appropriately. However Big Data Analytics has a few concerns including
Management of Data-lifecycle, Privacy & Security, and Data Representation. This
paper reviews the fundamental concept of Big Data, the Data Storage domain, the
MapReduce programming paradigm used in processing these large datasets, and
focuses on two case studies showing the effectiveness of Big Data Analytics and
presents how it could be of greater good in the future if handled
appropriately.
