  • Velocity: it is the measure of rate of data generation. i.e the data is how fast generated can be determined by its velocity.
  • Variablity : the processing or generation of data is consistent or inconsistent can fal under variability of big data.

However the data is generated at very fast rate so it have some challenges in processing like

  • If data generation is very high the processing and maintaining data gets very difficult.
  • storing the data of large volume can consume lots of space which further requires huge investments.
  • the velocity of data generation is variable so, we should be ready for worst case for example accelartion od data generation.
  • validating data is the one of the major issue of big data. due to is size.
  • Security of the data is essential part in 21 first century. because we are having a information or data revolution.

most of the challenges of big data can be overcome by advance computing and cheap technology for storage.
