13 Big Data Analytics: An overview

Today, we are in an information era where large amount of data are available for decision making. Those datasets which are huge in volume, fast in velocity, and large in variety are known as big data. Existing tools and technologies are not sufficient enough to handle such a big data and, hence, would face difficulty. As data is increasing with rapid pace, several new methods of solutions are studied, analyzed, and implemented to obtain essential hidden values and knowledge from the dataset. Analysts and researchers work hard to get valuable information from such huge sources of data (social network data, customer interactions with business sites, etc.). Big data analytics is nothing but the application of advanced analytic techniques on big data. This paper is a step toward discovering different analytic tools and techniques that would be beneficial while dealing with big data in various fields.
