Solution Architecture and Usage

Journl Streamed is a unified health data platform based on the FHIR standard. It provides a consistent API layer for systems interacting with patient data, including EHRs, apps, and analytics tools.

Core Architectural Features

Journl Streamed uses a FHIR-aware relational storage layer based on PostgreSQL. Health data is stored using native FHIR structures. On top of this storage, Journl Streamed exposes a rich set of APIs while a comprehensive REST API provides full access to data via standard FHIR operations. Additional APIs include GraphQL and event-driven subscriptions for real-time integration. Journl Streamed also includes modules for user management, access control, and auditing.

Journl Streamed consolidates and standardizes data from various sources into a single FHIR-based repository. This enables Journl’s applications to be loosely coupled from backend systems while working with a unified data model. It is capable of serving a wide range of use cases, including clinical data consolidation, analytics, mobile health apps, and external system integrations.
