Big data refers to extremely large and complex datasets that are too large for traditional data-processing application software to handle. It is generally characterized by:

- Volume: Massive amounts of data generated from various sources.
- Velocity: Data is generated at a rapid speed, requiring real-time processing.
- Variety: Data comes in different formats, structured, unstructured, and semi-structured.
- Veracity: Emphasizes on the quality and accuracy of the data.
Real-World Implications of Big Data
Big data has transformed various industries by enabling more informed decision-making through the analysis of vast amounts of information. In healthcare, it enhances patient care by predicting disease outbreaks and personalizing treatments. Retailers use big data to optimize supply chains, tailor marketing strategies, and improve customer experiences. Financial institutions leverage it for fraud detection and risk management, while in transportation, it improves route planning and traffic management. Additionally, big data is pivotal in environmental monitoring, helping track climate change and natural resource management. Its applications are vast, driving innovation and efficiency across multiple sectors.
