PROJECT 12
INVENTORY SYSTEM

Introduction

For Project 12, we will explore the complexities of inventory management using Object-Oriented Programming (OOP). This project will harness the power of OOP to design and implement a robust and scalable inventory management system. Through this project, students will learn how to structure and organise code to manage complex data and functional requirements efficiently.

What You Will Learn

• Encapsulation:
  Master the technique of encapsulating data within classes using private attributes and public methods, ensuring that all interactions are safe and managed through controlled interfaces.

• Facade Pattern:
  Learn to simplify complex system interactions using the facade pattern, which provides a simplified interface to more complex underlying code structures, enhancing ease of use and system maintenance.

• User Interface Development:
  Develop skills in building intuitive and functional user interfaces that interact seamlessly with backend logic, improving the overall user experience and system usability.

Labs:

The three labs below will guide you through the completion of this project, each building on the knowledge gained in the previous one:

Lab 1 - Encapsulation Revisited

1. • Begin by creating an Item class that encapsulates item details such as name, price, and quantity with private attributes and public getters and setters.

   • This lab sets the groundwork for understanding how data can be securely managed within an object, providing a solid foundation for more complex interactions.

Lab 2 - The Facade Pattern

1. • Extend the system with an InventoryManager class that acts as a facade to handle complex inventory management operations, such as adding, updating, and removing items.

   • Explore the practical application of the facade design pattern to reduce complexities in system interaction, which is particularly useful in scenarios where the underlying system may change frequently.

Lab 3 - The User Interface

1. • Develop a command-line interface (CLI) that allows users to interact dynamically with the InventoryManager. This lab focuses on implementing a user interface that uses the facade to manage user requests and system responses effectively.

   • Apply your knowledge of encapsulation and the facade pattern to ensure that the UI provides a clean, error-free interaction experience, demonstrating how front-end and back-end systems integrate.
