Architecture Diagram
Noun · Development
Definitions
A visual representation of a system's major components, data flows, boundaries, and dependencies. Good architecture diagrams make relationships and trust boundaries obvious rather than merely listing every service box in the estate.
In plain English: A picture that shows how the major parts of a system fit and work together.
Example: "The onboarding improved once the team updated the architecture diagram to show how the API gateway, queue workers, and billing service actually interacted."
