What is Big Data?

Large datasets that are too complicated for conventional data processing technologies to handle are referred to as “big data.” Size isn’t the only factor; other factors include the data’s variety, speed of flow, value, and reliability. These traits are often referred to as the “5 V’s”:

Volume: Terabytes to petabytes of data, in enormous quantities.

Velocity: The rate at which information is generated, for example, in real time.

Variety: Consists of both structured and semi-structured forms.

Veracity: Reliability and quality of data

Value: The potential benefits and information

Big Data, to put it briefly, is the driving force behind current business intelligence, artificial intelligence, and digital transformation projects.
