What Do You Understand about Big Data? 

Big data can be defined as a collection of data elements that have a high volume, velocity, and variety. These characteristics of big data are also known as its three Vs. 

In laymans terms, big data can be defined as highly complex data sets that cant be managed by any traditional means of data processing. However, these complex data sets can be used advantageously to tackle significant business problems. 

Here are the three Vs of complex data sets or big data: 

  • Volume: This characteristic defines the amount of data that needs to be processed. You’ll have to process major chunks of unstructured data that can contain thousands of unknown values. 
  • Velocity: This is defined as the rate at which a computer receives the data and acts on it.
