Big Data Definition
Big Data refers to the massive and complex sets of data that exceed the capacity of traditional data processing methods. It encompasses both structured and unstructured data, including text, images, videos, and more. Big Data is characterized by its volume, velocity, variety, and veracity – often referred to as the “4 Vs.”
Characteristics of Big Data
- Volume: Big Data involves a vast amount of data, often ranging from terabytes to petabytes.
- Velocity: Data is generated and updated rapidly, requiring real-time processing and analysis.
- Variety: It encompasses diverse data types, including structured, semi-structured, and unstructured data.
- Veracity: Big Data may contain inconsistent, incomplete, or inaccurate information, making data quality a challenge.
Big Data Analytics Tools
