Integration App Overview

Integration App allows System Administrators to configure data integration pipelines for healthcare data via a user interface. Healthcare systems (e.g. EHR) can route, filter, and transform data over different protocols (e.g. MLLP, SFTP, HTTP, FILE.). It can provide integration for heterogeneous, high volume and/or time sensitive data following established integration patterns.

Architecture

Integration App consists of following components:

Integration App

Integration Application contain Integration UI along with Zuul filters(e.g. audit). It allows System Administrators to configure data pipelines for healthcare data via a user interface.

Integration Configuration

This service allows admin users to perform create, update, delete, deploy and undeploy data pipeline via RESTful api. Data pipeline configurations are stored in micro-service local database. This service supports following features:

• Encryption / Decryption of Data pipeline properties like credentials to access secure endpoint.
• Versioning of Data pipeline configurations
• Import / Export of Data pipeline configurations. Export will only export the last version.

Integration Worker

Data pipelines are deployed / undeployed using this micro-service. This micro-service is with apache camel integration. It binds Data Pipeline configurations and Camel context together. It is configured to listen to a JMS topic. It returns success / failure responses on a JMS queue. It will support following capabilities:

• Deploy action: Read Data Pipeline configurations (on JMS topic) and create a dynamic route consisting of Source and Destination endpoints, Processors (Filters, Transformers), Intermediate endpoints and associate the route with Camel context.
• Undeploy action: Gracefully unbind the Camel route from Camel context.
• Micro-service restart: Auto deploy data pipelines which are already in STRATED state.
