  1. Volume: As the name suggests there is huge data that is collected and then processed further. As you, all will not be aware that the volume of data plays a very important role. And data is characterised as big data according to its volume/ size. So it is an important characteristic in defining big data.
  2. Variety: Variety of data means the different forms of data that are both structured and unstructured.
  3. Velocity: The velocity of data means the rate at which data is generated. It is also an important factor that at which speed data is  generated and then processed that decides the usage of data accordingly.
  4. Variability: This refers to inconsistency in the data which hurdles the data handling and management.

Big Data Processing Benefits

The data generated is then processed, processing of data has different types of benefits such as:
