Introduction
At the heart of any enterprise electronic medical record system lies a robust, explicit representation of how care information is stored. The structure of this data model dictates the scalability and flexibility of a system. The OpenMRS collaborative therefore invests continuous effort into shaping the OpenMRS data model using knowledge and experience gleaned from practical experiences from the Regenstrief Institute, Partners in Health, and all of our developmental partners around the world. The core of this data model addresses the who, what, when, where, and how of medical encounters. You may view a current image of the data model used in OpenMRS 1.9.0. Data models of previous releases are given below. This model is divided into ten basic domains.
