CASE ANALYSIS

Scenario

A dealership service department needs to schedule vehicle repair appointments, assign work orders to mechanics, track parts and services, and generate invoices for customers.

Key decisions

  • Model customer and vehicle ownership
  • Separate appointment status from work order status
  • Use inheritance for employee roles
  • Aggregate services and parts into work orders

When to reuse this

Use when designing or documenting the data model for a vehicle service/repair scheduling system or similar booking workflows.
