Different analytical techniques for big data analysis: A review

Big data refers to any collection of data so large and complex that it exceeds the processing capability of conventional data management system and techniques. Big data is the hot topic of research now a day. The paper gives some ideas about the research area to look into. It has been done as a part of literature survey for the P.hd work. The paper can be taken as the literature review of the existing paper in the area of Security, Machine learning, Health care, Neural Network, Rough Set Theory and Fuzzy Logic. The Security and privacy are the hot topic of research in Big data. Major contribution to this paper comes from Healthcare sector. The Machine learning too has its own role to in the big data analytics. This paper also covers the rough set theory and the neural network contributions to the big data. It also includes the challenges and the scope for research for the each paper. It also gives some insights to all the research paper in the area of big data, helpful for those who are doing research in big data.
