System Architecture

The banking system follows a backend-focused architecture, built with Node.js and Express.js. The system utilizes a RESTful API to handle client-server communication and follows the MVC (Model-View-Controller) pattern.

The key components of the system include:

• Controllers: Responsible for handling incoming requests, processing data, and generating responses.
• Models: Represent the data entities and handle interactions with the database.
• Routes: Define the API endpoints and their corresponding controllers.
• Middlewares: Provide additional functionalities such as authentication, request validation, error handling, etc.
• Database: Stores user and account data. In this project, we use MySQL as the database system.
