SN: The class diagram contains the key principles, reservation into the hotel by the guests. Other principles will be checking the room availability for booking, assigning one or many rooms to the guests, checking into the hotel and departure or checking out from the hotel.

Slide 3: Backend Coding Implementation

 
Figure 2: Backend Coding
(Source: Google Colab)

SN: This figure shows two classes, Guest and Room. The Guest class comprises different attributes which are the name, name of the guest who wants to register in the hotel and book a room, room number, the specific room numbers that the guest wants to book if available. Check in date the attribute that stores the date of the guest’s check into the hotel and check out date the attribute that stores the date when the guest departs from the hotel.

The Room class comprises different attributes which are the room number, the specific room numbers that the guest wants to book if available. Room type the attribute that stores the date of the guest’s assigned room in the hotel and price per night the attribute that stores the price to pay for the night stay in the hotel.

Slide 4: Backend Coding Implementation

Figure 4: Backend Coding
(Source: Google Colab)

SN: The payment class has attributes, name of the guest, room_number and total amount. This payment class has two subclasses which are Cash Payment and Credit Card Payment. The class hotel has attributes, name and rooms. The name attribute is the name of the hotel and the room attribute is the rooms in the hotel. This class has different objects that are checked in that are defined with attribute guest.

This object is responsible for room booking to the guest by retrieving the personal information of their guest, room number if  not occupied by another guest and the check in and check out dates. The check out object of the class Hotel is responsible for departing the guest by retrieving the room number of the guest if  the room number entered wrong by any chance either of the two messages will be shown that are Room room number is not occupied or Room room number is not available. Either way the message will show check out successfully.

The next object will visualize the room details  that are allocated to guests. Another object is generate payment which is responsible for generating the payment options and look after for successful payment. The calculate total amount object calculates the payment amount as per night stay.

Slide 5: Backend Coding Implementation

 
Figure 5: Backend Coding
(Source: Google Colab)

SN: This figure visualizes 4 choices in the code. If the user chooses the first choice, the user will be able to book a room in the hotel by sharing the personal details, room number, check in date and check out date. The user will be booked in the hotel if the room is not already occupied. If the user chooses choice 2 and choice 4 the user will be able to check the room details that the user booked and the user will be able to check out. The choice 5 looks after the payment for the room stay as per nights. The choice 6 will allow the user to exit from the system.
