Correct Answer :
D. All of the mentioned above
Large datasets can accumulate in a short amount of time in Big Data environments, since data arrives at lightning speed and accumulates in massive quantities. From the perspective of an enterprise, the velocity of data can be defined as the amount of time it takes for data to be processed once it enters the business's perimeter. In order to keep up with the rapid input of data, businesses must develop highly elastic and available data processing solutions, as well as the associated data storage capacities.
