Abstract:
Electronic Health Records (EHR) are a collection of all individuals health data, in an electronic form, generated during relevant interactions with the healthcare system. The federated database systems provides intercommunication between different and autonomous data units, which enables sharing data. This paper aims to be a state-of-art on the requirements to take into account when developing a federated system. For that, we did a literature review on PubMed, ISI Web of Knowledge, Scopus and Google Scholar. Federated systems must ensure interoperability using open standards; guarantee the system value through high quality services; have modular architecture to allow developments, maintenance and evolutions, and finally, enable the “monotonic” systems with an incremental evolution. When developing these systems we have to avoid semantic, functional and instance conflicts to ensure the correct functionality. We concluded that federated systems are a good option in health's domain. The
y allow a high volume of data storage in healthcare that can be accessed in any place, at any time, by health professionals. Thus, we believe that federated systems are a tool to improve the quality and efficiency of health care.
