Store — Clinical Data Repository (CDR) consists of the Clinical Data Repository and associated services that enable authorized users to manage data appropriate for their roles. This is a scalable implementation of the Fast Healthcare Interoperability Resources (FHIR) specification that provides a standard representational state transfer (REST) application programming interface (API) for interacting with clinical data (create, read, update, delete [CRUD]). Rather than an analytical repository, it provides an HL7 FHIR-based store that acts an operational data repository that supports a client defining their relevant access control rules for institutional data access.
