Shipment and Package Management System

This project provides a simple system for managing shipments, packages, customers, and airline earnings. It includes models representing customers, packages, shipments, and airlines, and supports calculating earnings based on delivered packages.

Features

• Customer Management: Represents customers with a unique identifier, name, and address.
• Package Management: Allows tracking of packages with details like height, width, weight, and cost.
• Shipment Tracking: Shipments have origins, destinations, status (e.g., delivered or in transit), and packages.
• Airline Earnings Calculation: An airline can have multiple shipments, and it calculates its earnings based on delivered shipments.
