The importance of this field has increased over the past few years because of a massive explosion in data generated from diverse sources such as social media, sensors and IoT devices. The research and business sectors are increasingly interested in big data analytics as a means for determining trends within large datasets. The deployment of sensor networks, cyber-physical systems and internet of things (IoT), have generated large amounts of data in many areas such as healthcare, social media. It allows creating the smart city, agriculture finance education. It collects data from different sources for example sensors, social media platforms and banking records.
