ABSTRACT
Big data are extremely large data sets that are so complex and unorganized. These large data sets are analyzed computationally to reveal patterns, trends related to human behavior and interactions. The three types of data are structured, semi-structured, and unstructured. Every big data has played a vital role in fighting COVID-19. Many countries used big data that helped them to reduce cross-infections, allowing the countries to get back to work and stabilize their economy. Big data was used to collect information for different other types of health crises also earlier. Artificial intelligence and machine learning involve many other types of novel data like images, movies, audio, and so many other things that don’t fit into standard relational databases; that’s the variety of big data where AI has been so useful. There are a lot of data science tools to help in analysis. Windows Azure is a Spark and Hadoop service in the cloud. It offers good enterprise-grade security.
