What is Hotel Reservation System?
A hotel reservation system is a piece of software that allows clients to book directly with the hotel online, bypassing the need for middlemen. It enables guests to design their vacation at their leisure.
It’s a software application that shows your live pricing and inventory across all of your channels in real-time, allowing guests to choose their travel dates and complete their reservations.
What is UML Sequence Diagram?
In software engineering, the UML sequence diagram depicts object interactions in a sequence of events. Therefore, the hotel reservation system sequence diagram shows the scenarios and how they communicate with each other to function correctly.
According to lucidchart.com, a UML sequence diagram helps software engineers and business experts figure out what the project should perform and how to describe a process that is already in place. It’s a form of interaction diagram since it shows how a group of things interacts and in what sequence.
A sequence diagram is a useful tool for documenting a system’s needs and fleshing out its architecture. Because it depicts the interaction logic between the items in the system in the time order in which they occur, the sequence diagram is quite valuable.
UML Sequence Diagram Description
The sequence diagram of hotel reservation system is used to look at the behavior of multiple objects within. This is good for showing how objects work together and in what order the events occur. It shows objects that communicate within the hotel reservation system, with messages going from them to each other down the process in a certain order.
The hotel reservation system sequence diagram shows how objects interact and how they happen sequentially. This specifies how messages move from one object to another in a way that makes sense.
UML Sequence Diagram for Hotel Reservation System (Illustration)
The designed sequence diagram for hotel reservation system gives you the exact scenario when the project is in use. This design presents the actual sequence of events and interactions when using the system. It uses symbols to represent the included objects and their roles in the hotel reservation system sequence diagram.
The illustration is based on the main process of the hotel reservation system. It can still be modified and added with your desired functions and scenario. It is more effective and efficient to manage and monitor the users’ activities using the log records in hotel reservations.
Hotel Reservation System Sequence Diagram (Explanation)
The explanation for the hotel reservation system sequence diagram elaborates how the illustration works. It has the figures which will clarify the sequence of activities and their alternatives. The box figures represent the object, the stick man is for the user, and the broken lines are for the lifelines. Vertical arrows then present messages.
The sequence diagram is designed to portray a timeline that starts at the top and gradually lowers to show the sequence of interactions. Each item has a column, and arrows indicate the messages that are sent between them.
The hotel reservation system sequence diagram has several boxes (objects): hotel reservation system, system accounts, reservation services, and reservation details. Its users are the personnel in a hotel and the messages have a flow showing the alternative in every decision.

Advantages of Sequence Diagram
The UML sequence diagrams are commonly used by developers to model the interactions between components in a single-use case. They show how the various components of a system interact to perform a function, as well as the order in which the interactions occur when a certain use case is executed. here are the advantages of designing a sequence diagram:
- A sequence diagram depicts the timeline and order in which messages are sent between devices to carry out process functions.
- Sequence diagrams are based on objects rather than classes.
- Used to step-by-step model a system’s process.
- Sequence diagrams are a great way to model the dynamic properties of your system.
- It aids programmers in determining the overall message flow between objects that perform use-case logic.
Steps in Developing Sequence Diagram
Time needed: 10 minutes.
Here’s the complete guide and steps in developing and designing your sequence diagram for the Hotel Reservation System.
- Finalize the purpose of the project
The first step in doing your sequence diagram is to finalize what your project is all about. The long and registration sequence diagram portray the scenario when a user registers and tries to access a certain system. Then this idea will give you other initiations on what to include in the project.
Take note that you as the developer and your client (if there is one) can decide on what functions and features should be included in your project. It’ll include anything as long as the function or feature is related to the idea of your project.
- Place your users or objects
The project users in the sequence diagram will always be based on your targeted users. You can create a design for each of your users or put them all in one design. Just be mindful of having a clear and precise illustration.
On the other hand, the object is represented by a rectangle with the object’s name underlined. The object name, the object name, and its class, or only the class name can all be used to name an object (anonymous object).
The sequence diagram depicts a group of objects connected by lifelines as well as the messages they exchange over time during the interaction.
- Add the lifelines in each user and object
A lifeline represents each instance of interaction. As it moves downhill, it represents the passage of time. Broken vertical lines show the next events that happen to an object during the charted process. A named rectangular shape (object) or an actor symbol is used to start Lifelines.
The lifeline sequence diagram is symbolized by a broken line connected to its head (object) that represents the lifetime of the object.
- Structure the sequence of messages (interaction)
A message is a representation of communication between objects or between an object and its surroundings. An event, a triggered operation, or a primitive operation are all examples of messages. A message in the metamodel denotes a certain sort of communication.
In UML diagrams, messages are represented as labeled arrows, with the arrowhead indicating the call’s direction. When a message is sent to an object, the name of the method being called on the receiving object is shown in the text associated with the message.
In a sequence diagram, a message is a named element that describes one sort of communication between interaction lifelines. The message describes not only the form of communication but also the sender and receiver. Usually, two things happen the transmitter and the recipient (the points at the ends of messages).
- Add alternatives (if needed)
When a scenario needs to choose between two or more message sequences, the alternative combination fragment is employed. It represents the logic of “Otherwise, if. One way for distinguishing which fragment is which “operator for fragments” is to put “alt” in the name box of the frame, also known as the “frame name box.
Different process conditions are denoted by the term “alt. Only one of the options will be implemented. The term “opt” means a workflow phase that can be skipped.
- Add the X symbol as the lifeline end
When the object’s lifeline is completed, you can add an X to the end of it to indicate that it has been destroyed. A rectangle represents a recurrence or loop in a sequence diagram.
A sequence diagram is a useful tool for documenting a system’s needs and fleshing out its architecture. Because it depicts the interaction logic between the items in the system in the time order in which the interactions occur, the sequence diagram is quite valuable.
It is a type of interaction diagram that depicts objects as lifelines running down the page, with messages rendered as arrows from the source lifeline to the target lifeline to describe their interactions through time. Complex procedural logic is not intended for sequence diagrams.
You need to know the diagrams used to design and develop the Hotel Reservation System. That is because you cannot perfectly create a fully-functional system without it. But if you create this sequence diagram, you will know the series of processes and interactions that implies the system’s function. A sequence diagram guides the programmers with the system’s behavior through its’ interaction diagram.
The sequence diagram is used to model the system’s sequence of events. It describes the interaction between the users and the system. By completing the Diagrams per module or process, you will quickly achieve your desired system. Check out our Related and Recommended Articles for more Learning and Information.
