Big Data is a phrase used to mean a massive volume of both structured and unstructured data that is so large it is difficult to process using traditional database and software techniques.The data is collected from a number of sources including emails, mobile devices, applications, databases, servers and other means.The importance of big data doesn’t revolve around how much data you have, but what you do with it. You can take data from any source and analyze it to find answers that enable cost reductions, time reductions, new product development,optimized offerings and smart decision making.
