Flight Ticket Reservation

Description

Design and implement an application to reserve flights based on source, destination and date. The application should take care of the following aspects:

• Repository of flight information containing airline name, flight number, source, destination, start time, end time, frequency (days on which the flight is active), total number of seats in the aircraft(capacity)
• Ability to search for flights based on source, destination anddate
• Reserve 'n'numberof seats on a particular fight based on availability of seats.

APIs:

1. Search for flights based on source, destination anddate
2. Userbeingabletoreserve'n'numberofseatsonaparticularfight(thisAPI should keep availability of seats on that flight inmind)
3. View reservations for a users (both past andupcoming)

Expectation:

• Clean professional levelCode
• Modelling of core entities and relationships betweenthem.
• Your code needs to be demonstrable. To do this, you can need to have an API based solution either as a WebApp, MobileApp or even providebasic API calls to run through the above mentionedworkflows.
• Workflows for creation of flight repository are not required. This could be pre- loaded as a part of applicationstartup.
• User Identification but notauthentication
• Backend Database is optional. However modelling should becomplete
Project info
Server url- http://localhost:8080
Database- Mysql
Java version- 1.8.0_242
Project Type- Maven
Framework- spring boot
Dependencies- spring web,spring data Jpa
run these commands to setup mysql database for application before running the application jar
-- drop database if exits
DROP DATABASE IF EXISTS flight_db;

-- create database name
CREATE DATABASE flight_db;

-- create user with password
CREATE USER 'flight_user'@'localhost' IDENTIFIED BY 'flight_password';

-- provide all the permission
GRANT ALL PRIVILEGES ON flight_db. * TO 'flight_user'@'localhost';
