• Efficient Queries: Guidance on select_related, prefetch_related, values/values_list, and annotations to optimize performance.
• Transactions & Migrations: Best practices for atomic operations and multi-tenant migrations with django-tenants.
• Use Case: A multi-tenant app that requires efficient data access across tenants while keeping models clean and testable.
