Big Data Career- a 360 Degree View
In the last decade people have been calling Data sexy and Big Data, well they are calling it a mind-blowing phenomenon that is fast changing the way we live and work. It is one of the fascinating evolution of the 21st century, and it has revolutionized the tech industry in ways we could not have imagined. It is said that the digital universe is doubling every two years, and will reach 40,000 Exabyte (40 trillion gigabytes) by 2020. It is also said that if we take all the data we have and place it on CD’s and they were stacked up, it would form five separate piles that would all reach to the moon. Impressive, isn’t it?
Big Data has four dimensions: volume, variety, velocity, and veracity. It can be explained as a collection of structured and unstructured data, from traditional and nontraditional sources, too large and complex to process using on-hand, more traditional database management tools and applications.
As Big Data evolved, it became more about what organizations were doing with this data. It encompassed the insights derived from this humongous (Volume) data, that could often be untrustworthy (Veracity), come from varied sources in varied formats (Variety) and could evolve, transform, and exceed current processing capacity (Velocity).
