So, what exactly is big data? According to Wikipedia, “Big data is a field that deals with methods for analysing, systematically extracting information from, or otherwise dealing with data sets that are too large or complex for traditional data-processing application software to handle.”

According to Gartner’s definition, Big data refers to high-volume, high-velocity, and high-variety information assets that necessitate cost-effective, innovative data processing in order to improve insight and decision-making.”

Big data is a broad technology. Therefore, a lot of people find it difficult to grasp its concept. Therefore, the IT industry has made it easier to quantify what big data is, and isn't, with the help of three V’s, which are:

  • Volume: Volume refers to the amount of data generated through online applications, websites, and portals. It has been reported that every day more than 2.3 trillion gigabytes of new data are being created.
  • Velocity: The speed of data being exchanged and processed. Every day, Facebook users upload 900 million photos, Twitter users send 500 million tweets, YouTube users upload 0.4 million hours of video, and Google users conduct 3.5 billion searches. Big data allows us to accept the incoming flow of data and process it quickly.
  • Variety: All structured and unstructured data generated by humans and machines is classified as variety in big data.
