Big Data refers to the vast and complex sets of information that are generated at an unprecedented scale and speed, often exceeding the processing capabilities of traditional data management systems. Originating from various sources such as social media, sensors, mobile devices, and business transactions, these data sets are not just large in volume but are also diverse in variety and velocity, often referred to as the "Three Vs." The fourth and fifth Vs, veracity and value, are also commonly included to emphasize the importance of data quality and the actionable insights that can be derived from it. The handling and analysis of big data require specialized tools, algorithms, and expertise, allowing organizations to uncover patterns, trends, and correlations that can transform decision-making, drive innovation, and provide a competitive advantage.
