What are the Big Data Characteristics ?

Now, the question comes, How we will define that data is big data.

There are three main characteristics, by which be can differentiate the big data.

  • Volume :  Amount of Data from GB to PB
  • Velocity : Speed of Data, data rate of growing, like growing 2 TB per day
  • Variety : Range of data type and source (text, image, video, audio etc.)

These are called ā€œ3Vā€ of bigdata.

Fourth V is also added as ā€œveracityā€

Veracity : Veracity refers to the biases, noise and abnormality in data.
