The term "big data" refers to extremely large datasets that exceed the processing capacity of traditional data handling tools. Characterized by the three V's—Volume, Velocity, and Variety—big data involves managing and analyzing vast amounts of structured and unstructured information. Organizations use big data analytics to derive insights, identify trends, and make data-driven decisions. This technology plays a vital role across industries, ranging from healthcare to finance, enabling improved customer service, optimized operations, and enhanced forecasting.
