Information models for data sharing

Abstract

How to share/exchange data among different databases is still a critical issue. In the medical domain, there is an absolute need for national/international agreement on standard ontologies, terminologies and data models. A global solution is far from being achieved, but in the meantime there are a number of sub-optimal solutions that can be adopted. In this paper two of them, which have already provided, or are close to providing, practical implementations will be described.
