Key Characteristics of Big Data (the "3 Vs"):
Volume :
Big data involves extremely large amounts of data, often measured in terabytes, petabytes, or even larger units.
Velocity :
Data is generated and processed at high speeds, requiring real-time or near real-time analysis capabilities.
Variety :
Big data encompasses a wide range of data types, including structured (databases), unstructured (text, images, video), and semi-structured (logs, sensor data).
Veracity :
The quality and accuracy of the data are crucial, as inaccurate data can lead to flawed insights.
Value :
