What is big data analytics? It is the process of unearthing trends, patterns and correlations to make informed decisions. Large amounts of data that are complex cannot be interpreted by human strength and determination alone or by traditional management systems. A sophisticated intelligence is needed to do the work. This is where big data applications are helpful across the business arena and the healthcare industry is no exception. For an example, medical professionals are now using big data to find drug effects and pinpoint early indications of illnesses (Thelin, 2020). Big data in healthcare is amassing large volumes of information created by digital technologies through the collection of patient records, which helps to manage performance that is too large and complex for traditional technologies.
