UML Diagram for Hotel Management System

UML diagrams for the Hotel Management System. Following are the different UML diagrams like Components, Activity, Use Case, and Sequence diagrams of the Hotel Management System.

The Hotel Management application will help to manage the hotel. It allows the admin or the hotel owner to manage the day-to-day process of Hotel management and bookings conveniently.

UML Diagram for Hotel Management System

We’ve compiled structural UML diagrams i.e. component diagrams, and three types of behavioural UML diagrams i.e. Activity, Sequence, and Use Case diagrams for the Hotel Management System. We have also explained the data flow diagram (DFD) for this project.

Here, we have two users, who will be interacting with the system. With the help of these diagrams, one can get a better understanding of the project. This web application is developed to provide users with an online medium where they can see different hotels and make bookings. Admin is who will manage the overall application; whereas the user can book hotels.

Component diagram for Hotel Management System

The diagram below shows the structural relations between components in a Hotel Management System. The connected components by lines represent relationships within the systems. In the diagram, it can be seen that there are components namely hotel, booking, customer, and account.

It shows how the component connects to the other components while using the system. Everything from the account details to hotel booking to payment flow can be seen in the component diagram.

Once the user logs in to the system, the user can view a list of hotels, select the desired hotel and place a booking following the payment process. While placing the booking, the user’s account details get accessed and the booking is confirmed after completing the payment.

Activity diagram for Hotel Management System

Activity diagrams in UML display the functionalities of various activities and flow in management processes and software systems. The flow in the activity diagram can be sequential, branched, or concurrent.

Admin can view the list of customers. Admin can manage the category of hotels and can update all hotel detail. Admin can view booking history and detail. Admin can manage payment and transactions.

Online users can browse or search hotels, view specific hotels, book them, view, and checkout. Users can view booking history at any time. Customers can make payments for the booking and view the payment history.

Sequence diagram for Hotel Management System

Sequence diagrams in UML are used to illustrate the sequence of messages between objects in an interaction. A sequence diagram consists of a group of objects that are represented by lifelines and the messages that they exchange overtime during the interaction.

The user can view the hotel lists, view the price of a selected hotel, book the hotel, and make payments for the booking. Users can book hotels or rooms after filling out some simple forms. Users can manage all the booked history as well.

As soon as the payment is confirmed, the user’s booking will be completed and the user can check it in the booking history section.

Use Case Diagram for Hotel Management System

A UML use case diagram can create a broad, high-level view of the relationship between use cases, actors involved, and systems being performed.

As you can see from the examples below, use cases are represented by oval shapes, and the lines then show at which point an actor/user participates and interacts with their corresponding use case. You can see where each actor is involved within the entire process (and where they’re excluded).

For example, Admin will be able to add different hotels and view a list of hotels in the system. Whereas, users can access the system for hotel bookings.

DFD Diagram for Hotel Management System

A data flow diagram represents the flow of information for any process or system. It shows the system with its relationship to external entities. Here, we can see how the users and the process flow work in a system.

After logging in, Admin and User will land on the home page where they can manage their profiles. Admin can add, view hotels, manage prices, view bookings, check the availability of the hotel, etc.

Users, on the other hand, can book the hotel online. Users can search for a particular hotel, select a hotel, and book for the same. Users can also view their bookings and payment confirmation on the system.
