Characteristics of Big Data

Characteristics of Big Data, called 3Vs (and 4Vs also used) are:​

Volume:

• - is related to size of the data and hence the characteristic.
• - Size defines the amount or quantity of data, which is generated from an application(s).
• - The size determines the processing considerations needed for handling that data.

Velocity:

• - The term velocity refers to the speed of generation of data.
• - Velocity is a measure of how fast the data generates and processes.
• - To meet the demands and the challenges of processing Big Data, the velocity of generation of data plays a crucial ro​​​le.

Variety:

• -comprises of a variety of data.
• -Data is generated from multiple sources in a system.
• -This introduces variety in data and therefore introduces ‘complexity’.
• -Data is in various forms and formats.
• -The variety is due to the availability of a large number of heterogeneous platforms in the industry.
