Both the HL7 standard and software development methodology exist at a sufficiently high level of abstraction to support multiple interoperability requirements, even when these requirements conflict with each other. Some newbies portray HL7v3 as a "silver-bullet" solution. Unfortunately, neither HL7v3 nor separate components of the standard such as HL7 Reference Information Model (aka RIM) are "solutions". They are just new layers that separate end-user applications from the communication media, not a fundamental change in how data is communicated in existing computing infrastructure.
The focus of this book is to introduce readers to HL7 version 3 to the point that they confident enough to start building their own healthcare data exchange interfaces.
This book strives to teach you HL7v3 standard conventions by referencing to HL7v3 Normative Edition and implementing request and response messages for a fictitious Eligibility Query Service. The implementation of the service is based on default (universal) and localized schemas. The conformance of the implemented messages with the HL7v3 standard is also reviewed.
