Abstract: Big Data can be combined with new technology to bring about positive conversion in the health care segment. A technology aimed at making Big Data analytics a certainty will act as a key element in transforming the way the health care industry operates today. The study and analysis of Big Data can be used for tracking and managing population health care effectively and efficiently. This also plays a vital role in delivering preventive care. Health care will change a great deal as it becomes a data-driven industry. But the size of the data, the speed at which itís growing and the threat it could cause to individual privacy mean mastering it is one of biomedicine's most critical challenges. Hiding within this huge amount of data is knowledge that could change the life of a patient. Health information that can be extracted from patient records is another rich resource of data. In my research I would explore how big data can enhance healthcare segment in country like India which has a huge population and huge medical complexities. I addition to this I would also explore problems faced by big data, obstacles in using big data in the health industry, how big data analytics can take health care to a new level by enhancing the overall quality of patient care. Today, a significant proportion of the cost and time spent in the drug development process is attributable to unsuccessful formulations. By enabling researchers to identify compounds with a higher likelihood of success, Big Data can help reduce the cost and the time to market for new drugs. Also, by integrating learning from medical data in the early stages of development, researchers will now be able to customize drugs to suit aggregated patient profiles.
