What is Data VOLUME?
Volume nothing but quantity is the amount of data that we are going to store analyse and use. The size of the data is the volume of the Data.
Example: Every time we watch a video, upload a video on YouTube, the data is generated that's huge volume.

What is Data VELOCITY?
Velocity is nothing but speed is the time taken to store or retrieve the data. It's basically the speed of data accessed. Data velocity is the speed at which data is generated.

What is Data VARIETY?
Variety is nothing but various forms of data. The data is usually in different formats, like Structured data and unstructured data.

Structured data is data that has a proper structure.
Example : 
  • Phone numbers

  • Product inventories
Unstructured data is data that does not have a proper structure.
Example :
  • Media files like images, videos
  • Text files like docs and PPT
