Design an Anti-Corruption Layer for a Legacy Hospital EHR

FreeVerified credential4 weeksAdvanced

Overview

What this challenge is about.

Map the legacy EHR's HL7 v2 message schema (ADT, ORM, ORU segments) to the new platform's domain (Patient, Encounter, Order, Result). Identify the 6-10 anti-patterns in the legacy model (e.g. boolean status fields, null-as-meaning, magic codes) and the translations needed. Build the ACL in Python (or Go) consuming the sandbox EHR's MLLP feed and emitting clean domain events. Cover translation correctness with property-based tests (Hypothesis or fast-check). Deliver source code, a 10-page architecture writeup, and a translation-rules catalog for ongoing maintenance.

The Brief

What you'll do, and what you'll demonstrate.

Design and prototype an Anti-Corruption Layer translating a legacy HL7 v2 EHR feed into a clean domain model the modern care-coordination platform can build on safely.

Earning criteria — what you'll demonstrate

  • Design an Anti-Corruption Layer protecting a clean domain from legacy contamination
  • Translate legacy data models without leaking their concepts into the new design
  • Apply property-based testing to translation correctness
  • Document translation rules in a form ops + clinical staff can audit
