What is Big Data?

It’s more than just “lots of data.” Big Data refers to enormous and complex datasets that require advanced tools and technologies to collect, store, process, and analyze. (Often in real time)

The 5 Vs of Big Data

Volume: Massive amounts of data (terabytes to petabytes)
Velocity: Data generated at lightning speed
Variety: Structured, unstructured, and semi-structured data types
Veracity: Ensuring data accuracy and trustworthiness
Value: Extracting business insights from raw data

Where Big Data is Making an Impact - Industry Insights

Across industries, Big Data is enabling organizations to optimize operations, personalize experiences, and uncover hidden opportunities.
