Big data system for health care records

Abstract

So far, medical data have been used to serve the need of people's healthcare. In some countries, in recent years, a lot of hospitals have altered the conventional paper medical records into electronic health records. The data in these records grow continuously in real time, which generates a large number of medical data available for physicians, researchers, and patients in need. Systems of electronic health records share a common feature that they are all constituted from open sources for Big Data with distributed structure in order to collect, store, exploit, and use medical data to track down, prevent, treat human's diseases, and even forecast dangerous epidemics.

Integrated Document-based Electronic Health Records Persistence Framework

“…Healthcare data is complex, dynamic, intermittent, and diverse in nature. Furthermore, HIS applications` access patterns usually need their scale, performance, and flexibility requirements to surpass their transactional needs [16,17]. Thus, NoSQL data stores are more suitable to meet the specifications of distributed EHRs systems [18].…”
