Data Lifecycle
End-to-End Data Flow Sequence
Hospital EHR sends real-time HL7 v2 ADT/ORU messages over encrypted VPN to Ingestion Gateway.
Gateway transforms messages into standardized FHIR R4 JSON resources, writing to Bronze Delta Lake tables.
Spark ETL pipeline validates schemas, resolves patient duplicate IDs, and writes to Silver normalized tables.
De-identification pipeline strips patient PII to create HIPAA-compliant Gold datasets for research teams.
Clinical researchers query population health datasets using standard SQL and Tableau dashboards.

Unauthorized Research Access to Identified ePHI
Enforce Databricks Unity Catalog role-based access control with dynamic column-level data masking.
Architecture FAQs
Frequently asked blueprint questions
FHIR (Fast Healthcare Interoperability Resources) is the global standard for exchanging healthcare data electronically, mandated by CMS and ONC regulations.
It organizes data into Bronze (raw ingested data), Silver (cleaned and normalized data), and Gold (aggregated business-level clinical data).
