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 “3V” of bigdata.
Fourth V is also added as “veracity”
Veracity : Veracity refers to the biases, noise and abnormality in data.
