Introduction Big data is characterized by its complexity and scale. To understand and manage big data effectively, experts refer to the “Three Vs”: Volume, Velocity, and Variety. These characteristics explain how big data differs from traditional datasets. Additionally, tools like MapReduce help process large-scale data in a fast and efficient way using parallel processing. In
