Distributed System for Vehicle Speed Violation Management

This application is a distributed system based on microservices architecture, employing an event-driven approach following the Event Sourcing and Command Query Responsibility Segregation (CQRS) patterns. Its primary purpose is to manage traffic violations resulting from speeding incidents detected by automatic radar systems.

Microservices Overview

1. radar-service

   • Responsible for radar management (command & query operations).

2. registration-service

   • Manages vehicle information, including registration (command & query operations).

3. infraction-service

   • Handles the management of traffic violations (command & query operations).

Additional Services

• discovery-service (Spring Cloud Eureka Server)

  • Enables service discovery within the application.

• gateway-service (Spring Cloud Gateway)

  • Acts as a gateway for routing and load balancing.

Technology Stack

• Axon Framework and Axon Server

  • Utilized for implementing Event Sourcing and CQRS.

• MySQL

  • Database management system for persistent data storage.

• Maven

  • Build and project management tool.

• Java 17

  • Programming language for application development.

Getting Started

1. Clone the repository.

   git clone https://github.com/BrodyGaudel/cqrs-and-event-sourcing---radar-management-system.git
