                   Big Data
             The term has been in use since the 1990s
          Big data is data sets that are so big and complex that 
          traditional data-processing application software are 
               inadequate to deal with them.
           Lately, the term "big data" tends to refer to the use 
           of predictive analytics, user behavior analytics, or 
          certain other advanced data analytics methods that 
          extract value from data, and seldom to a particular size 
                     of data set
