HDR Usage Model
The following chart illustrates the usage model for the HDR platform:

The HL7 version 3 Reference Information Model (RIM) provides the basis for how HDR represents healthcare data. HDR uses this model to develop a collection of application services that are exposed through a J2EE compliant application programming interface, including the following:
- Services that help to consolidate patient data into unified records.
- Services that align the terminologies and coding system into a single unified concept-based representation.
- Rigorous security and auditing services.
- Persistence services for key healthcare business processes.
Developers use this foundation to build the next generation of applications for healthcare organizations. HDR provides a unified representation for the key business objects underlying these applications. Resulting application suites thus enjoy a high degree of interoperability.
The underlying healthcare data model is embedded in a comprehensive Enterprise Data Model. This broad foundation unifies the management of all of the data used in a healthcare enterprise.
HDR also includes a powerful set of messaging services that provide interfaces to systems developed outside of the HDR architecture. These messaging services manage the exchange of data between an HDR application and other information management systems, including legacy systems. The HDR Repository can thus become a comprehensive patient record for the entire enterprise.
HDR supports a transactional view of healthcare data. This view captures the dynamics of healthcare data as it evolves during business processes and supports operational applications. It also can support basic business intelligence functionality. For example, OBIEE or other similar products can be used to build reports directly on the HDR Platform.
Alternatively, a data warehouse can be built on the HDR Repository. This data warehouse can support more complicated reports and analysis. Because of the data quality services provided by HDR, the resulting decision support functionality can be based on a comprehensive view of the enterprise.
