CASE ANALYSIS

Scenario

A pet clinic and pharmacy need a database to manage customers, their pets, clinic visits, medication prescriptions, and online orders. This ER diagram captures the required entities and relationships.

Key decisions

  • Added optional prescription-orders relationship to allow over-the-counter purchases.
  • Used OrderItem as a separate table to handle multiple medications per order.
  • Connected Prescription to Pet, Clinic, and Medication for complete medical tracking.

When to reuse this

When designing a system for a veterinary pharmacy that manages pets, owners, clinics, and prescription-based or direct medication orders.
