Managing heterogeneous medical data: Learning from experiences in telemedicine

Abstract

The Internet of Things is one of the most promising technical revolutions of our age. The idea of integrating sensors to common objects and linking to the Internet offers a wide range of new possibilities. However, establishing standard communication protocols, storing heterogeneous data and guaranteeing security to the transmitted information need to be studied. As a support, web services have been released to establish the way how web applications interchange information by using XML, JSON or other plain formats. In this paper, we describe a general Back-End solution to store heterogeneous data collected from different sources. We used the stack named “MEAN” to program web services, and JSON as the data model to interchange information. On this study, we show the advantage of using JSON and a NoSQL database to integrate different solutions developed in projects that involve the Internet of Things philosophy.
