Big data refers to the data sets that possess one or more of the following characteristics, which include large volume, high speed, or velocity of data generation, and a variety of data. From the context of big data, volume refers to the amount of data or the size of data sets, while velocity refers to the speed at which data is generated, retrieved, and streamed. Variety refers to different types of structured data, such as numeric data in traditional databases as well as unstructured data, including video and audio files and others. These inherent characteristics make it difficult for such data sets to be processed and analyzed using traditional data analytics tools. This leads to the development of advanced big data technologies
