As their name implies, "big data" stand for enormoue amounts of data, produced in various sectors, that cannot be managed through using traditional software or web platforms, as they by far outstrip existing capabilities in terms of storage, processing and analytics. Particularly in the health sector, which traditionally generates huge volumes of data, the utilization of Big Data through specialized applications promises significant developments in terms of management, decision making, disease and epidemic forecasting, and significant reductions in healthcare costs. The purpose of this thesis is to explore the role of Big Data in the healthcafre sector, along with the challenges and opportunities they face, as well as their main applications. From a methodological point of view, a bibliographic review was conducted, based on research for related articles in a number of online databases such as Google Scholar, Scopus, Pub Med, and Research Gate.
