The question arises of what and how to process such data from various sources which could be structured as well as unstructured and in a distributed manner? Hadoop is open source framework, based on distributed computing, which is capable of storing and processing Big Data, which may comprise of structured, unstructured as well as semi-structured data. In this paper, we summarize the basic operations performed on healthcare data in a Data Management Lifecycle.
