Banking Application with ZeroMQ

Overview

This is a Banking Application built using Java that incorporates ZeroMQ (ZMQ) for messaging and communication between different banking services. The project follows Object-Oriented Programming (OOP) principles, includes exception handling, and implements multithreading to efficiently manage banking operations.

Features

• User Account Management: Create, update, and delete bank accounts.
• Deposit & Withdraw: Secure transactions with proper validations.
• Balance Inquiry: Fetch the account balance efficiently.
• ZeroMQ Integration: Efficient message passing for distributed communication.
• Multithreading: Handles multiple user requests concurrently.
• Exception Handling: Ensures robustness against incorrect operations.

Tech Stack

• Java (Core logic & OOP implementation)
• ZeroMQ (For inter-service communication)
• Multithreading (For handling concurrent transactions)
• Exception Handling (To manage errors efficiently)

Installation

Prerequisites

Ensure you have the following installed on your system:

• Java (JDK 11 or later)
• ZeroMQ (JZMQ or jeromq library for Java)

Steps to Run

1. Clone the repository:

   git clone https://github.com/yourusername/banking-zmq.git
   cd banking-zmq

2. Install dependencies (if using Maven or Gradle):
   • For Maven:

     <dependency>
       <groupId>org.zeromq</groupId>
       <artifactId>jeromq</artifactId>
       <version>0.5.2</version>
     </dependency>

   • For Gradle:

     dependencies {
         implementation 'org.zeromq:jeromq:0.5.2'
     }

How It Works

• The server handles all banking transactions and communicates via ZeroMQ sockets.
• The clients send requests (e.g., deposit, withdraw, balance check) using ZMQ messaging.
• The server processes requests in a thread-safe manner and responds to clients asynchronously.

Future Enhancements

• Implement database integration for persistent account storage.
• Add security features like authentication & encryption.
• Extend support for multiple currencies.
• Create a web UI for better user experience.
