Car Rental System Activity Diagram

The Car Rental System Activity Diagram is a UML behavioral modeling. It shows the system’s behavior by presenting the flow of activities from one to another. The possible flow of activities can be in order, split, or continuous. The activity diagram for car rental system uses symbols to define the overall workflow of the activity diagram. It is composed of activities, decisions, and paths (flows).

The activity diagram visually depicts a set of actions or control flows in a car rental system. People, software components, and computers can all do these tasks. It describes the processes in a use case diagram and is commonly used in business process modeling. Modeled activities can either be sequential or concurrent. Its’ illustration can be used to illustrate the process of implementing 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 simple. 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 Car Rental System Activity Diagram

The importance of car rental system activity diagram is that it enables interaction between developers and clients. This is done by helping them visualize the system’s functionality in various degrees of detail.

The activity diagram involves major activities to define the workflow of the project. These activities come with user decisions that result in more effective interaction. Being a programmer, these are the important roles that the car rental system should have.

UML Activity Diagram for Car Rental System

The UML Activity Diagram for Car Rental System is one of the methods used for project development. It represents the system’s major activities and constraints that lead to paths that the project includes. They were labeled properly to guide programmers and users about the behavior of the Car Rental System.

Additionally, the activity diagram depicts software operations as a series of actions. These diagrams are used to document and define the system processes and use cases. It can clarify difficult use cases to simplify and improve any process. An activity diagram also models the system’s actions, functions, and processes.

Car rental system activity diagrams provide the same basic goals as the other UML diagrams. It illustrates the system’s dynamic behavior. The flow of messages from one object to another is shown in other UML diagrams. The activity diagram, on the other hand, shows the flow of messages from one activity to another.

Car Rental System Activity Diagram: Benefits

The Activity Diagram Benefits are as follows:

  • An Activity Diagram helps in understanding how an algorithm works.
  • It describes the steps that a UML use case takes.
  • Shows how users and the system interact in a process or workflow.
  • Clarify difficult use cases to simplify and improve any process.

Draw the Activity Diagram for Car Rental System

Time needed: 5 minutes.

Here are the steps in developing (designing) the activity diagram for car rental system.

  • Step 1: Familiarize Activity Diagram Symbols

    Activity Diagram Symbols – are used to create an Activity Diagram which was presented here. Their symbols and applications must be familiarized before you build the Activity Diagram.
    Activity Diagram Symbols
    • Start – is the beginning of the action is symbolized by a filled circle. A dark circle represents the initial node.
    • Action – is a stage of an activity in which users or software accomplish a certain task. Actions are represented by round-edged rectangles.
    • Decision – represented by a diamond and is used to symbolize a conditional branch in the flow. It has two or more outputs and a single input.
    • Swim Lanes – are the lanes drawn as boundaries, and the activities drawn in the same lane as the organization’s activities. Swim lanes must be arranged in a logical order.
    • Activity Flow – is another name for the connectors in the diagram that illustrate the flow between processes (activity).
    • End or Terminator – is the last phase of the activity. An indicated black circle represents the final node.

    Each of these activity diagram symbols shows the overall system behavior. Emphasizing the System’s behavior would be much easier by using these Activity Diagram symbols.

  • Step 2: Identify the flow of actions.

    After familiarizing the symbols used in designing an activity diagram, you then need to identify the flow of actions included based on your use case diagram. The flow of actions or steps in an activity diagram describes the sequence or series of activities that happen when a user invokes the car rental system.

    An action represents a discrete unit of functionality in an activity diagram. It is used to describe the steps in a use case diagram. The flow of control and data to and from other activity nodes is specified by the incoming and outgoing activity edges of actions. When all of the input requirements are met, the activity’s actions begin.

  • Step 3: Add the Actors (users) involved.

    Actors carry out their actions on things, transforming them into other objects or changing their state. This actor is someone or something that interacts with the system from outside the system.

    The Actors are usually placed as labels on the swimlanes to indicate that the action or step performed was from them or the system. This way will help readers and developers how will the system behave or interact with actors or vice versa. It will help you as the developer understand better the system.

  • Step 4: Trace the flow of activities.

    Action or control flows (paths or edges) are utilized to depict the change from one activity state to the next. There might be several entering and outgoing action flows in this notation. It can also be sequential, branching, or run at the same time.

    The control flow determines the activity’s flow, and the inbound arrow initiates a single activity step. The flow continues along the outgoing arrow after this phase is accomplished. The flow of objects and data within activities is described by the object flow.

Conclusion:

You need to know the diagrams used to design and develop the Car Rental System. That is because you cannot perfectly create a fully-functional system without it. But if you create this activity diagram, you will know the possible inputs and scenarios that the system should process and perform. Not only that, you will find out the needed processes and connect them to the other UML Diagrams.

The activity diagram can be used to model the system’s activity flow. These systems are also captured in an activity diagram, which describes the flow from one system to the next. By completing the Activity Diagrams per module or per process, you will easily achieve your desired system. Check out our Related and Recommended Articles for more Learnings and Information.
