Due to technological advances, vast data sets (e.g. big data) are increasing now days. Big Data a new term; is used to identify the collected datasets. But due to their large size and complexity, users cannot manage with their current methodologies or data mining software tools to extract those datasets. Such datasets provide them with unparalleled opportunities for modelling and predicting of future with new challenges. So as an awareness of this and weaknesses as well as the possibilities of these large data sets, are necessary to forecast the future.
