Bank System Project

A simple and small scale simulation of a real-world banking system implemented in C++ using object oriented programming concepts and 3-tier architecture.

Overview

The Bank System project is designed to reflect a real-world banking operations in a small scale and simple functionallity. Leveraging the principles of object-oriented programming (OOP) and clean code practices, this project embodies some clarity in its structure.

Key Features

3-Tier Architecture

Separation of UI, Business, and Database layers for enhanced modularity and maintainability.

File Handling with C++ "fstream"

Utilizes the power of C++ and the fstream library for seamless data storage and retrieval.

Object-Oriented Programming

The project embraces key OOP concepts to ensure robustness and flexibility:

• Classes and Objects: Use of classes and objects for encapsulation and abstraction.
• Encapsulation: Protects the internal state of objects, restricting access to only necessary components for improved security.
• Inheritance and Polymorphism: Enhances code reusability and readability through inheritance and polymorphic behaviors.
• Abstraction: Focuses on essential properties and behaviors, hiding unnecessary details to simplify complexity.

Clean Code

The implementation adheres to some clean code principles:

• Fixed Naming Conventions: Consistent naming methods across the system for improved clarity.
• Readability: Ensures the codebase is easy to understand and navigate.
• Maintainability: Designed for ease of maintenance, reducing the cost of future updates.

Screens and Functionality

The system contains over 20 screens, mirroring some of real-world bank-system interactions.

Main Features

1. Login Screen

   • The system user can only access the system with an existing username and password.
   • Users have three attempts to log in successfully; otherwise, the system will close automatically.

   

2. Main Screen

   • After a successful login, the main screen with 10 options is displayed to the user.

   

3. Access to System Features

   • Only admins can access all system features.
   • Other users are granted access to specific features. Unauthorized attempts result in denial.

   

4. Manage Clients

   • Users can add, delete, update, and find clients.

5. Make Transactions

   • Perform various transactions: deposit, withdraw, transfer between accounts, veiw all clients balances, and view transfer logs.

6. Manage Users

   • Admins can add, delete, update, find, and view the list of users.

   

7. Show Login Registers

   • View login records for basic security.

8. Currency Exchange Integration

   • Merged currency exchange project for seamless currency operations.
