Big Data refers to extremely large datasets that can be analyzed computationally to reveal patterns, trends, and associations, especially relating to human behavior and interactions. The growth of digital data from various sources such as social media, sensors, transactions, and more has led to the term 'Big Data' becoming increasingly significant. In the context of Artificial Intelligence (AI) and Machine Learning (ML), Big Data provides the foundation for training complex models that require vast amounts of information.
Characteristics of Big Data
Big Data is often characterized by the three Vs:
- Volume: The sheer amount of data, ranging from terabytes to zettabytes.
- Variety: The diversity of data types, including structured, semi-structured, and unstructured formats.
- Velocity: The speed at which new data is generated and processed.
In addition to the three Vs, some experts also acknowledge other dimensions such as Veracity (data quality) and Value (extractable insights).
