Increase in storing the Electronic Health Records (EHR) of patients has developed a large scale. Healthcare data analytics is rapidly emerging with huge potential for organizations to provide healthcare by reducing the costs and improving healthcare decisions. Analytics help in gaining the information to improve decision making by using advanced data mining tools. A healthcare information and management system uses big data analytics for operational excellence. As Electronic Healthcare records are unstructured in nature, big data adoption is gaining importance in processing and visualizing the data. Big data utilizes Hadoop framework to process the large data sets in distributing computing environment. This paper discusses the survey on the analyzation of EHR by using Big Data Analytics.
