Database

Journl Streamed employs a robust and flexible storage architecture using open-source PostgreSQL to manage both raw data and FHIR-structured data efficiently. This ensures high performance, scalability, and reliability, which are crucial for handling healthcare information.

Key Components

Primary Database

• The primary database is responsible for storing FHIR resources. It is optimized for fast read and write operations, ensuring quick access to healthcare data.

• Journl Streamed uses a combination of relational and NoSQL databases to balance complex querying capabilities with scalability needs.

Raw Data Repository

• Raw data, such as HL7 messages, CSV files, or other formats, is stored in a dedicated repository before being mapped to FHIR resources.

• This repository supports various data formats and acts as a staging area for data transformation processes.

Transformation Layer

• The transformation layer is responsible for mapping raw data to FHIR resources. It ensures that data is converted accurately and consistently, adhering to FHIR standards.

• This layer includes validation mechanisms to ensure the integrity and quality of the transformed data.
