System Architecture

Presentation Layer (Frontend/UI)

Description: This layer handles the user interface and user interaction. It communicates with the backend to display dynamic content and ensures a seamless user experience.

Technologies:

• React.js for building interactive and reusable UI components.

• HTML5/CSS3 for structuring and styling.

• TailwindCSS for design and layout.

• JavaScript for functionality and logic.

Key Responsibilities:

• Display data fetched from the backend.

• Send user inputs and interactions to the backend for processing.

• Provide responsive and interactive UI/UX.

Application Layer (Backend/API)

Description: The application layer processes the business logic, handles authentication, and serves as the intermediary between the frontend and the database.

Technologies:

• Node.js as the server runtime.

• Express.js for handling HTTP requests and routing.

• JWT for authentication.

• RESTful API for communication with the frontend.

Key Responsibilities:

• Process and validate requests from the frontend.

• Implement business logic and rules.

• Manage authentication and user sessions.

• Expose APIs for the frontend to fetch data or trigger actions.

Data Layer (Database)

Description: This layer manages data storage and retrieval. It ensures data is persisted securely and efficiently.

Technologies:

• MySQL for relational data storage.

• PhpMyAdmin for database interaction.

Key Responsibilities:

• Store application data such as user profiles, transactions, or content.

• Handle data queries, updates, and relationships.

• Ensure data consistency and integrity.

System Architecture Diagram

Here’s how the components are interconnected:

• User Interface (React): Sends requests to and receives responses from the backend.

• API Gateway (Express.js): Processes frontend requests, applies business logic, and communicates with the database.

• Database (MySQL): Stores and retrieves data as required by the backend.
