201809 FHIR Storage and Analytics
Previous tracks:
Track Name
FHIR Storage & Analytics ([1])
Track Overview
With this track we want to put together people, which are interested in implementation and usage of FHIR persistence layer, implementing FHIR servers on top and analysing FHIR data.
We hope this group can produce useful feedback for FHIR community and potentially propose new aspects for standard - like SQL on FHIR or FHIRPath for databases.
Another goal is to collect solutions and best practices to store and query FHIR data, using popular databases.
Please fill out: TODO [TODO Track Registration Spreadsheet]
Submitting WG/Project/Implementer Group
We want to create S&A working group or FHIR Foundation Project.
Justification
Initial set of questions to be answered or discussed
- How we can organise our FHIR Foundation Project?
- How to store FHIR data?
- What is database schema design?
- SQL (as common query language) on FHIR
- FHIR data representation for storage
- FHIRPath subset for databases
- How to approach FHIR search?
- Best practices for popular databases (postgresq, spark, mongo, bigquery etc)?

Discussions
SQL on FHIR
Initial notes for creating a standard representation of FHIR that is directly usable in scalable SQL-based systems.

FHIR data representation in database
JSON and other JSON like formats like yaml, edn, avro, protobuf are very popular in avantе-garde of programmers, some modern databases now could understad JSON as first-class data-structures, that’s why we think, good design for it is strictly required for FHIR adoption.

FHIRPath subset for databases
It worth to discuss subset of FHIRPath, which is implementable in databases
Issue to discuss - https://github.com/fhir-fuel/fhir-fuel.github.io/issues/10
Scenarios
Scenario: Bulk Loader
Implement and demonstrate bulk loader script for your specific database.
- Provide Bulk Loader for your specific database to easily and efficiently load data from FHIR server thro Bulk API into db.
- Loader for Mitre Synthea (https://github.com/synthetichealth/synthea) - where source is file system as synthea generate.
- Loader for FHIR examples - zipped dir of resources and bundles in json
