Data that is complex in terms of volume, variety, velocity and/or its relation to other data makes it hard to handle using traditional database management or tools. Big data analytics refers to analysis techniques operated on data sets classified as "Big data". Today, every organization across the globe is faced with an unprecedented growth in data.
