Use Case Diagram for Event Management System

The use case diagram for online event management system is the behavioral diagram that summarizes activities done in the event management system and its user details. It depicts the graphical representation of the system’s behavioral structure.

Additionally, the diagram consists of processes (use cases) and users or “actors”. It uses defined symbols to describe the overall workflow of the event management system.

Use Case Diagram for Event Management System: Overview

What is a Use Case Diagram?

The use case diagram in software engineering shows the sample adaptive behavior of the event management system. It encapsulates the project’s functionality by incorporating use cases, actors, and their interactions.

Moreover, the diagram assists you in defining and organizing project requirements. This also provides a clear picture of the user and system relationships. Therefore, this diagram depicts the high-level functionality of a system including how the user interacts with it.

Importance of UML Use Case Diagram

To help the developers and enterprises in developing the system is the importance of the UML use case diagram. It includes the procedures from the viewpoint of users.

Furthermore, the diagram is the analysis methodology aids to identify, clarify, and organize project needs. This diagram works best with other UML Diagrams for Event Management System. Other UML diagrams include activity, class, sequence, deployment, and component diagrams.

The sample system use case diagram includes actors, processes (use case), and their relationships.

Event Management System General Use Case Diagram

This diagram shows the general processes or functions that the system could do and is based on the transactions needed in an Event Management.

Event Management System General Use Case Diagram

The general use case is the most common application of a use case diagram. It shows the system’s main components as well as the flow of information between them. With the help of this general use case, the programmer will have the basis on what could be put into consideration in creating the event management system.

Use Case Diagram using Include and Extend

Include and extend are indications that elaborate the proceeding diagrams. The label “include” indicates that the sub-processes of the main processes are included to complete the task. The “extend”, on the other hand, declares that the sub-processes can only be performed when needed.

This diagram specifies the included activities in completing a process or task. It will also help users determine the right way of managing the Event Management System.

Event Management System Specified Use Case Diagram

The role of this Use case Diagram using the include and Extend label is to inform your readers and users that some tasks and processes may be completed without invoking all the subtasks. They were only used when they were called or needed.

You can add more to this and it is up to you how will you create your use case diagram. Only be precise with your information and consider the use cases that should be included.

How to draw a Use Case Diagram?

Time needed: 2 minutes.

Here’s the complete guide on how to draw a use case diagram for event management system.

  • Step 1: Familiarize Use Case Diagram Symbols

    For beginners in the field of designing the diagram, you need first to familiarize the symbols to be used.

  • Step 2: Determine the targeted users

    The next step is to determine your targeted users. They will be the ones to use your project.

    You may ask the users about the typical activities done in the event system.

  • Step 3: Analyze the use cases included

    The gathered information from the users needs to be evaluated to know the general use cases.

    From the general use cases, you will see the sub-cases that are included. But, only the useful processes and circumstances related to the event management system.

  • Step 4: Plot the Use Case Diagram

    To plot the 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 from the users.

    You need to place first the users involved.

    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 interactions between the user/s and the system.

    Finally, put the container in the plotted diagram to separate the objects’ (users and system) scope.


The use case diagram is one of the methods that contribute to the event management system design and development. It helps developers know the possible inputs and scenarios that the project should process and perform.

Furthermore, you will find out the needed processes and connect them to the other UML Diagrams. The diagram is also applicable in modeling the software’s use cases (processes). It also captures the system’s flow from one process to the next.
