# Real-Time Chat Application for Drive School

This document outlines the design and implementation of a real-time chat application built with React Native, Expo, Node.js, Socket.IO, Sequelize, and MySQL. The application is designed for a driving school to facilitate communication between driving instructors and students. The application allows students to send messages to their assigned instructor and receive real-time responses. Instructors can also communicate with their students using the application. Additionally, the application sends push notifications to the students when they receive a new message.

## Architecture

The application is built using the following technologies:



- React Native and Expo for the mobile application frontend

- Node.js and Express for the server-side backend

- Socket.IO for real-time communication between the client and server

- Sequelize as the ORM for MySQL database



The client-side application is built using React Native and Expo, which allows for easy deployment to both iOS and Android devices.



## Database Design

The application uses MySQL as the database management system and Sequelize as the ORM.The database schema consists of four tables: ChatRoom, Candidat, Message, and Moniteur.



The ChatRoom table has the following columns:



- roomId: a string of up to 250 characters that serves as the primary key

- lastMessages: a string of up to 1000 characters that contains the last messages sent in the chat room

- candidatId: a string of up to 250 characters that references the primary key of the Candidat table

- moniteurId: a string of up to 250 characters that references the primary key of the Moniteur table



The Candidat table has the following columns:



- candidatId: a string of up to 250 characters that serves as the primary key

- cin: a string of 8 characters that represents the candidate's identification number

- solde: a double that represents the candidate's account balance

- nbSession: an integer that represents the number of sessions the candidate has signed up for

- nbsessionEffected: an integer that represents the number of sessions the candidate has attended

- amountPaid: a double that represents the amount of money the candidate has paid

- amountRequired: a double that represents the amount of money the candidate is required to pay

- phone: a string of 8 characters that represents the candidate's phone number

- accountStatus: a boolean that indicates whether the candidate's account is active or not

- accountType: a string of up to 150 characters that represents the type of account the candidate has

- pic: a string of up to 300 characters that represents the candidate's profile picture

- moniteurId: a string of up to 250 characters that references the primary key of the Moniteur table



The Message table has the following columns:



- messageId: a string of up to 250 characters that serves as the primary key

- messages: a string of up to 1000 characters that contains the message text

- sender: a string of up to 250 characters that represents the sender of the message

- receiver: a string of up to 250 characters that represents the receiver of the message

- isView: a boolean that indicates whether the message has been viewed or not

- chatRoomId: a string of up to 250 characters that references the primary key of the ChatRoom table
