The Big data has also been defined by the three Vs:
Velocity refers to the data is streaming into the server in real time. So, it gives better and useful result, also if the delay is very short. It will also better for Internet of Things (IoT) applications. Because IoT applications have health and safety ramifications that require real-time evaluation and action.
