ABSTRACT- this paper attempts to offer a broader definition of big data that captures its other unique and defining characteristics. Big data is the term for data sets so large and complicated that it becomes difficult to process using traditional data management tools or processing applications. This paper reveals most recent progress on big data and analytic methods used for big data. The potential value of big data analytics is great and is clearly established by a growing number of studies. There are keys to success with big data analytics, including a clear business need, strong committed sponsorship, alignment between the business and IT strategies, a fact-based decision making culture, a strong data infrastructure, the right analytical tools, and people skilled in the use of analytics. Main feature of this paper is its focus on analytics related to text audio and video big data.
