The rapid proliferation of data has lead to the necessity of big data. However the volume of big data is constantly growing. Big data comprises of extremely large data sets which are beyond the scope of management offered by commonly used software. Big Data mining can be described as a set of techniques and technologies used for extracting useful information from these large datasets or streams of data, which due to its volume, variability, and velocity, was not possible earlier. This paper presents an overview of big data, its current status, controversy, future scope and how it can play an essential role in fostering the growth and productivity of a company in today's cut throat competitive world.
