Problem Description: Hotel Management System

Overview: The objective is to design and implement a Hotel Management System that

manages the core operations of a hotel, focusing on guest management, room allocation,

booking management, and staff assignment. The system will handle interactions between

guests, rooms, bookings, and various categories of hotel staff, including managers, chefs, and

housekeeping. This system ensures efficient operation and a seamless experience for both

hotel staff and guests.

System Requirements:

Guest Management:

The system must store and manage guest information, including their unique

guest ID$,$ name, contact number, and email address.

Guests should be able to make bookings for available rooms during specific

dates.

The system should allow guests to view their booking history and update their

contact information as needed.

Guests can make multiple bookings, if they desire.

Room Management:

Each room in the hotel must be represented with a unique room number, type

$($e$.$g$.,$ single, double, suite$),$ status $($available$,$ occupied, under maintenance$),$ and

price per night.

The system should track room availability based on the check$-$in and check$-$out

dates of bookings.

The room status should be updated automatically based on bookings and

manually when under maintenance.

You should be able to check the total cost of the room.

Booking Management:

The system should enable guests to book rooms by specifying check$-$in and

check$-$out dates.

Each booking should consist of an unique bookingID, check in date, check out

date and total bill.

Each booking should be linked to a guest and a room, and should record the total

bill, based on the room charges

The system should allow for the calculate the total bill, generate invoices, and

handle booking cancellations.

Staff Management:

The system must store information about the hotel staff, including their unique

staff ID$,$ name, role $($e$.$g$.,$ receptionist, housekeeping, manager$),$ and contact

number.

Managers oversee the hotel's operations, including ensuring guest satisfaction

and coordinating staff.

Chefs are responsible for preparing meals, managing kitchen inventory and

planning the menu.

Housekeeping staff are responsible for cleaning rooms, maintaining cleanliness

in public areas, and report room status.

The system should track the tasks assigned to each staff member according to
