Entity Relationships

• A user may have roles like admin or staff.
• A product can have multiple product_images.
• Each product has a single inventory record.
• Customers purchase products via orders associated with suppliers.
• Each order contains multiple order_items linked to products.

---

Implementation Best Practices

• Security: Use JWT or OAuth2 for authentication; password handling with hashing and salting; enforce HTTPS.
• Data Validation: Validate and sanitize all API inputs rigorously.
• Pagination & Filtering: Implement on GET endpoints to optimize performance.
• Caching: Use Redis or Memcached for frequently accessed data (e.g., catalog).
• Error Handling: Utilize standardized HTTP status codes and descriptive messages.
• Backup and Recovery: Schedule periodic backups and disaster recovery plans.
• Extensibility: Modular API structure to integrate future features like discounts, customer reviews, or multi-warehouse support.
