What is Big Data?
Big Data refers to extremely large volumes of data that are generated and collected every day. This data grows rapidly and are too large and complex for traditional data management tools to store, process, and analyse efficiently.
Think about everything we do online, such as posting on social media, shopping online, streaming videos, or using mobile apps. All these activities create huge amounts of data. Today, organizations generate data on a massive scale, often measured in petabytes and zettabytes. By analysing this data, businesses can gain valuable insights and make better decisions.

- Variety: Refers to the different types of data generated, including structured, unstructured, and semi-structured data.
- Velocity: Refers to the speed at which data is generated, collected, and processed, often requiring real-time or near real-time analysis.
- Variability: Refers to the inconsistency and changing nature of data, including fluctuations in data volume, format, and meaning over time.
