OOP Parfumery - Final Version

Overview

This project is a Parfumery Management System created as part of the Object-Oriented Programming (OOP) class. The system allows users to manage Parfums, Employees, Sales, and Inventory within a parfumery store, incorporating several OOP concepts such as inheritance, polymorphism, encapsulation, templates, and the Singleton design pattern.

Features

1. Parfums Management

• The system can store and manage multiple perfume products.
• Each perfume (Parfum) can have multiple attributes like name, brand, price, rating, and a list of ingredients.
• It supports functionality to update ingredients, check the similarity between perfumes, and display detailed information about each perfume.

2. Employee Management

• Employees are represented by the Angajat class.
• Each employee can have details like name, position, activity status, monthly salary, and a list of recommended perfumes.
• It includes functionality to estimate future salary growth and manage free days for employees.

3. Sales Management

• Sales can be processed either as:
  • VanzareOnline: Online sales with home delivery.
  • VanzareInMagazin: In-store sales.
  • VanzareOnlineCuRidicare: Online sales with in-store pickup.
• Sales inherit common properties from a base class (Vanzare) and are specialized with additional features (such as loyalty programs for in-store sales).
• The system allows users to check which products are included in a sale and handles discount calculations.

4. Inventory Management

• The InventarMagazin class manages the stock of perfumes in the store.
• It provides functionality to check stock levels for different products, handle promotions, and calculate the total profit for the store.

5. Singleton Design Pattern

• The entire system is controlled by a Singleton class to ensure that only one instance of the parfumery management system exists.
• The Singleton class provides CRUD operations for Parfum, Angajat, Vanzare, and InventarMagazin.

Class Breakdown

1. Class: Produs

• Abstract base class for representing a product with functions to get and set product details.

2. Class: Parfum

• Inherits from Produs.
• Represents a perfume product with attributes such as name, brand, rating, price, and a list of ingredients.
• Supports similarity checking and ingredient combination between perfumes.

3. Template Class: ParfumerieIngredient

• A template class for handling ingredients in a perfume.
• It allows for storing the amount and chemical compounds of the ingredient.
• Supports combining ingredients and checking similarity between them.

4. Class: Angajat

• Represents an employee with attributes like name, position, activity status, and monthly salary.
• Includes a list of recommended perfumes for customers and free days for the employee.

5. Class: Vanzare (Base Class)

• Represents a sale with details such as customer name, employee ID, total amount, and purchased products.

6. Derived Classes: VanzareOnline, VanzareInMagazin, VanzareOnlineCuRidicare

• Specialized classes inheriting from Vanzare and adding additional functionality specific to online or in-store sales.
• Handle different payment methods, delivery times, loyalty programs, and discounts.

7. Class: InventarMagazin

• Manages the inventory of perfumes in the store.
• Tracks the number of perfumes in stock and calculates profits during promotional periods.

8. Class: Singleton

• Manages the whole system, ensuring only one instance of the management system exists.
• Provides CRUD operations and allows for interaction between perfumes, employees, sales, and inventory.

Key OOP Concepts Used

1. Encapsulation: All attributes are private or protected, and access is provided through getters and setters.

2. Inheritance:

   • Parfum inherits from Produs.
   • VanzareOnline, VanzareInMagazin, and VanzareOnlineCuRidicare inherit from Vanzare.

3. Polymorphism:

   • Virtual functions are used to provide different implementations for online and in-store sales.

4. Templates:

   • ParfumerieIngredient is a template class that works with different data types for ingredients.

5. Singleton Pattern: Ensures that there is only one instance of the parfumery management system throughout the program.

How to Run

1. Compile the project using a C++ compiler:

   g++ -o parfumery parfumery.cpp

2. Run the executable:

   ./parfumery

3. Follow the on-screen menu to interact with the parfumery management system.

Conclusion

This project demonstrates the practical application of OOP principles in managing a perfume store. By leveraging inheritance, templates, polymorphism, and design patterns, the system efficiently handles complex operations and interactions between different components.
