Though other protocols have superseded it, the application level of Open Systems Interconnection (OSI) stays as the most critical place to begin when it comes to the study of network architecture. The seventh level of the International Organization for Standardization (ISO) seven-layer communications model for Open Systems Interconnection (OSI) is referred to as Level 7.
Electronic Health information can be retrieved, exchanged, integrated, and shared through a framework that has been provided by HL7 and its members. This will define data transfer between parties, structure and data types, language setting, and other logistics required for integration between systems. These HL7 Standards are commonly used globally as they provide sturdy practices and evaluate health services. The data standards thus shared will be shared in a consistent, confidential, and uniform manner. These have paved the way for the development of Fast Healthcare Interoperability Resources (FHIR) as well as the adoption of APIs for health IT.
Our two major components of the HL7 Tool Kits are HL7 message encoder/decoder and HL7 message communicator.
