Big Data Knowledge
Big Data refers to the vast volumes of structured and unstructured data that inundate businesses on a day-to-day basis. However, it is not the amount of data that is important, but what organizations do with the data that matters. The term encompasses a range of technologies and techniques that enable businesses to capture, store, analyze, and leverage data to gain insights, improve decision-making, and drive innovation.
Definition of Big Data
Big Data is defined by the three Vs:
- Volume: The sheer amount of data generated from various sources, including social media, sensors, transactions, and more.
- Velocity: The speed at which data is generated and processed, requiring real-time or near-real-time analytics.
- Variety: The different types of data, including structured, semi-structured, and unstructured formats.
Sources of Big Data
Big Data can originate from various sources, including:
| Source | Description |
|---|---|
