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
