In today’s digital world, the amount of data being created globally is growing exponentially, with ninety percent generated in the last two years alone.

In business and industry data analytics is used to answer questions, predict trends or back up arguments. Real world examples include, in healthcare, finding out what drugs patients respond to in clinical trials. In retail, launching a targeted marketing campaign for a new product and in meteorology, forecasting weather events.
