Abstract: The volume of data that enterprise acquires every day is increasing rapidly. The enterprises do not know what to do with the data and how to extract information from this data. Analytics is the process of collecting, organizing and analysing large set of data that is important for the business. The process of analysing and processing this huge amount of data is called bigdata analytics. The volume, variety and velocity of big data cause performance problems when processed using traditional data processing techniques. It is now possible to store and process these vast amounts of data on low cost platforms such as Hadoop. The major aspire of this paper is to make a study on data analytics, big data and its applications.

Keywords: BigData, Hadoop, MapReduce, Sqoop and Hive.
