Car Rental System Use Case Diagram

The car rental system use case diagram in UML is the behavioral diagram that summarizes the activities done in the software. It’s usually depicted as the graphical representation of the car rental system‘s behavioral structure.

The car rental system use case diagram is composed of processes (use cases) and users or “actors”. It uses defined symbols to describe the overall workflow of the car rental system.

What is a Car Rental System?

Online vehicle rental software allows you to keep precise records of your whole fleet in one location, making day-to-day operations straightforward. Your business would be illegal if you didn’t keep proper documents, and no one could audit you. You wouldn’t be able to get insurance or anything else.

Customers can hire a vehicle through a car rental web-based system. This technology allows the company to make its services available to the general public via the internet while also keeping track of its performance.

Car rental companies usually work with people who need a short-term car, like people who don’t own a car, people who are traveling outside of their city, or people who have damaged or destroyed cars that need to be repaired or replaced

Importance of UML Use Case Diagram

The importance of the UML use case diagram is that it helps developers and enterprises in designing the car rental system. This includes the procedures from the viewpoint of users. It’s known as the project analysis methodology used for identifying, clarifying, and organizing project needs.

From the user’s perspective, the UML use case diagram specifies how the car rental system responds to a request. Each use case is broken down into a series of fundamental steps. It starts with the user’s goal and ends with the achievement of that goal.

Use Case Diagram in Software Engineering

The Use Case Diagram in Software Engineering shows the sample adaptive behavior of the car rental software. It encapsulates the project’s functionality by incorporating use cases, actors, and their interactions. It depicts the high-level functionality of the car rental system, including how the user interacts with it.

The car rental system use case diagram in UML will assist your team in defining and organizing project requirements. This provides a clear picture of the software’s included processes, events, and functionalities.

The use case diagram for car rental system project is discussed to elaborate the Include and Extend indication (relations). The sample use case diagram for car rental system presents a set of objectives that are used to calculate the system’s cost and complexity.

Car Rental System General Use Case Diagram

Car Rental System General Use Case Diagram – This diagram shows the general processes or functions that the system could do that are based on the transactions done by the system admin in managing their customers’ rental transactions.

Car Rental System General Use Case Diagram

The general use case is the most common application of a use case diagram. The use case diagrams depict the system’s main components as well as the flow of information between them.

Use Case Diagram for Car Rental System using Include and Extend

Use Case Diagram for Car Rental System using Include and Extend is used to elaborate the proceeding diagrams. The terms include and extend in the use case diagram are known as indicators.

The label include is used to indicate that the sub-processes of the main processes must be included to complete the task. The Extend, on the other hand, declares that the sub-processes can only be performed when needed.

Manage Customers’ Information and Status Use Case Diagram

Manage Customers’ Information and Status Use Case Diagram – The system admin should manage the customers’ rental information to track their cars and services availed. This will serve as the basis for the management, to sum up, their income and expenses.

Additional Knowledge

The objective of a use case diagram is to show the interactions of numerous items called actors with the use case and to capture the fundamental functionalities of a system. Through the diagrams, there are the use cases involved to define the core functions of a system. These processes were connected to produce a certain output.

How to create a use case diagram?

Time needed: 5 minutes.

The step-by-step guideline for creating the UML use case diagram for Car Rental System is discussed here.

  • Step 1: Familiarize Use Case Diagram Symbols

    Use Case Diagram Symbols – are used to create a Use Case Diagram which was presented here. Their symbols and applications must be familiarized before you build the Use Case Diagram.

    Use Cases – Ovals with a horizontal shape symbolize the various uses that a user might have.
    Actors (Users) – Stick figures depict people that are using the use cases.
    Indicators (Association) – are used to know the connection of the system’s function or processes with another process. Its vital role is to figure out which actors are linked to and which use cases are in complex graphs.
    Container – is a box that limits the scope of a system to specific use situations. Situations, where the system is used outside of the box, would be deemed outside of the system’s scope.

    Each of these use case diagram symbols shows the overall system structure. Emphasizing the System’s structure would be much easier by using these Use Case Diagram symbols.

  • Step 2: Determine the targeted users

    After the symbol familiarization, you’ll need to determine your targeted users. Your targeted users will be the ones to use your project.

    Your project is Bank Management System and you may ask the system users about the common activities that they do when doing tasks in the bank management system. The system’s activities may vary depending on the users of the proposed system and it will help you in proceeding with the next step.

  • Step 3: Analyze the use cases included

    Analyzation is very important in creating a use case diagram. It will help you understand the work of the diagram and avoid unwanted errors.

    The gathered information from the targeted users is very useful in creating a use case diagram. You need to evaluate these data and pick the general use cases.

    From the general use cases, you will see the sub-cases that are included in them. But only include the useful processes and circumstances related to the car rental system. Then you’re ready for the next step.

  • Step 4: Plot the Use Case Diagram

    To plot the use case diagram you will need the users, use cases, container (scope), and their indicators (association). You will base the flow of use cases on the evaluated information to have the exact Use Case Diagram.

    To plot your diagram, you need to place first the users involved and the process they will perform.

    Then place the figured use cases included in doing the process.

    After that, you will trace the association of the use cases to know the series of interactions between the user/s and the system.

    Finally, you put the container in the plotted diagram to separate the scope of the objects (users and system). This is to identify what are the processes that are under them or should be performed.

Conclusion:

The use case diagram is one of the methods used to design and develop the Car Rental System. This diagram helps developers know the possible inputs and scenarios that the project should process and perform. Not only that, you will find out the needed processes and connect them to the other UML Diagrams.

The use case diagram cannot only model the software’s use cases but can also capture the flow of the system from one process to the next. Achieving the desired software would be easier by completing the Use Case Diagrams per module or process. Check out our Related and Recommended Articles for more Learnings and Information.
