Banking System Simulation with Multithreading

Overview

This project is a simulation of a banking system, designed to demonstrate the use of multithreading for improved performance. The system handles various banking operations such as account creation, deposits, withdrawals, and balance inquiries. By leveraging multithreading, we aim to enhance the responsiveness and efficiency of these operations, especially under high load.

Features

• Account Management: Create and manage multiple bank accounts.
• Transactions: Perform deposits, withdrawals, and balance inquiries.
• Concurrency: Utilize multithreading to handle multiple transactions simultaneously.
• Synchronization: Ensure data consistency and thread safety with appropriate synchronization mechanisms.

Getting Started

Prerequisites

• Python 3.8+: Ensure you have Python installed. You can download it from python.org.
• Git: For cloning the repository. You can download it from git-scm.com.

Installation

1. Clone the repository:

   git clone https://github.com/your-username/banking-system-simulation.git
   cd banking-system-simulation

2. Install dependencies:

   pip install -r requirements.txt

Running the Simulation

To run the banking system simulation, execute the following command in your terminal:

python main.py

Multithreading Implementation

The main objective of this update is to improve performance using multithreading. Here are the key points:

• Thread Pooling: We use a thread pool to manage a pool of worker threads efficiently. This reduces the overhead of creating and destroying threads.
• Locking Mechanisms: We implement locks to ensure that account transactions are thread-safe. This prevents race conditions and ensures data consistency.
• Performance Metrics: We include timing functions to measure the performance improvement due to multithreading.

Code Structure

• main.py: The entry point of the simulation.
• account.py: Contains the Account class, which encapsulates account-related operations.
• bank.py: Manages multiple accounts and coordinates transactions.
• thread_manager.py: Manages threading operations and synchronization.
• tests/: Contains unit tests for different components of the system.

Usage

Creating an Account

from bank import Bank

bank = Bank()
account_id = bank.create_account("John Doe")
print(f"Account created with ID: {account_id}")

Making a Deposit

bank.deposit(account_id, 500)
print(f"Deposited 500 into account {account_id}")

Withdrawing Money

bank.withdraw(account_id, 200)
print(f"Withdrew 200 from account {account_id}")

Checking Balance

balance = bank.get_balance(account_id)
print(f"Current balance for account {account_id} is {balance}")

Running Concurrent Transactions

from thread_manager import run_concurrent_transactions

transactions = [
    {"type": "deposit", "account_id": account_id, "amount": 100},
    {"type": "withdraw", "account_id": account_id, "amount": 50},
    # Add more transactions as needed
]

run_concurrent_transactions(bank, transactions)
