FHIRbase is an open source relational storage for FHIR targeting real production.
While crafting Health IT systems we understand an importance of a properly chosen domain model. FHIR is an open source new generation lightweight standard for health data interoperability, which (we hope) could be used as a foundation for Health IT systems. FHIR is based on a concept of resource.
FHIR® is a next generation standards framework created by HL7. FHIR combines the best features of HL7 Version 2, Version 3 and CDA® product lines while leveraging the latest web standards and applying a tight focus on implementability.
Also we learned that data is a heart of any information system, and should be reliably managed. PostgreSQL is a battle proved open source database which supports structured documents (jsonb) while preserving ACID guaranties and richness of SQL query language.
PostgreSQL is a powerful, open source object-relational database system. It has more than 15 years of active development and a proven architecture that has earned it a strong reputation for reliability, data integrity, and correctness.
Here is the list of PostgreSQL features that we use:
We actively collaborate with PostgreSQL lead developers to craft production ready storage for FHIR.
Why are we doing this inside a database?
We decided to implement most of FHIR specification inside a database for scalability reason (all data operations are done efficiently in a database).
This approach also gives you a possibility to use FHIRbase from your preferred lang/platform (.NET, java, ruby, nodejs etc). We have implemented FHIR compliant server in clojure with small amount of code - FHIRPlace.
And there is an option to break FHIR specification abstraction (if required) and go into the database by generic SQL interface and complete your business task.
FHIRbase implements 80% of FHIR specification inside the database as procedures:
- meta-data resource storage (StructureDefinition, ValueSet, SearchParameter, etc)
- CRUD on resources with history
- search operations with indexing
- transactions
- resource validation
- referential integrity
- terminology
- guides for java, .NET, python, ruby, js
- Star us on GitHub
- If you encountered a bug, please make an Issue
- Contribute to FHIRbase − see dev/README.md
