Big Data is a term that refers to data sets that are too large, complex, or diverse to be processed by traditional methods1. Big Data is characterized by four V's: volume, variety, velocity, and veracity2. Volume refers to the amount of data being generated and collected. Variety refers to the different types of data, such as structured, unstructured, or semi-structured. Velocity refers to the speed at which the data is created, processed, and analyzed. Veracity refers to the quality and reliability of the data.
