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 dm:view a current image of the data model. This model is divided into seven basic domains.
Domains
- Concept: Concepts are defined and used to support strongly coded data throughout the system
- Encounter: Contains the meta-data regarding health care providers interventions with a patient.
- Form: Essentially, the user interface description for the various components.
- Observation: This is where the actual health care information is stored. There are many observations per Encounter.
- Order: Things/actions that have been requested to occur.
- Patient: Basic information about patients in this system.
- User: Basic information about the people that use this system.
