Abstract: Analyzing and predicting the knowledge from the big data plays a critical role in the real world environment which needs to be concerned more to provide an efficient treatment for the health care patients. Handling and treating the patients online may generate large volume of data dynamically. These large volume of data need to be handled more carefully to predict accurate result. And also establishing connection among multiple patients in the real world environment leads to more troubling process. In this article, more methodologies that were introduced previously to handle large volume of data in terms of scalability and the security are discussed deeply. And also, the methodologies that concentrate on gathering data from multiple locations without anomalies are discussed in detail.
