Class Diagram for Student Management System

The class diagram for student management system is a form of structural (UML) diagram that depicts the data structure of student system. This is designed by displaying the system’s classes, attributes, methods, and the relationships between classes.

Class diagrams reveal the class structure blueprint of Student Management System. It is used to model the items that make up the system and depict their relationships. This is to define the function of an object and the operation it provides.

The Importance of Student Management System Class Diagram is that it helps in visualizing the classes that make up the system. It displays the classes’ connections and reports their characteristics, operations, and methods used.

Class diagram helps you understand the project’s classes. It gives you a lot of information on the structure of your system. It also provides a rapid summary of the synergy that occurs among the various system classes, as well as their qualities and interactions.

The class diagram aims to show the system’s static view. This diagram can be mapped with object-oriented languages, making it appropriate during the construction process.

The UML Class Diagram for Student Management System in UML describes an entity or a group of objects with similar structure and characteristics. A box with three rows is used to represent them.

The class diagram is presented in a rectangle with three partitions. The upper part is for the name of the class, the middle is for its attributes and the bottom is for the methods. These partitions will clearly emphasize the details of the classes.

Class diagrams provide the same basic goals as the other UML diagrams. They are one of the most useful forms of UML diagrams because they clearly map out a system’s structure by representing its classes, characteristics, operations, and relationships. Creating these diagrams isn’t as difficult as it may appear with the UML diagramming tools.

Student Management System Class Diagram: Benefits

Their Benefits are as follows:

  • It aids in the better and more accurate illustration of data models.
  • Explains more straightforward and clear understanding of the overall system or process’ overview and schematics.
  • It provides a sense of direction.
  • Gives a lot of information on the structure of your systems.
  • Summarize the system’s static perspective.
  • Enumerates how the parts of a static view work together.
  • Defines the functions that the system does and Object-oriented programming languages are used to create software applications.

Simple Class Diagram for Student Management System

The Simple Class Diagram for Student Management System resembles a flowchart in which classes are represented as boxes with three rectangles inside. The top rectangle has the class’s name; the middle rectangle contains the class’s properties; and the bottom rectangle contains the class’s methods, commonly known as operations.

As you can see through the illustration, the classes were determined which is symbolized by boxes. They were designated with their corresponding attributes and shows the class’ methods. Their relationships are also plotted to show the connections between classes and their multiplicity.

Just bear in mind that when you create your own class diagram, you have to be specific. That is because, it will affect your project development. Do not worry because you can use the sample given as your project reference or you may also create your own.

Student Management System Class Diagram (Explanation)

The classes identified for Student Management System were the admin, students, instructors, enrollment, course, subjects and transactions. Their roles were explained in the middle part and called as their attributes. The function can be seen by reading through its’ methods.

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

Steps in Creating Class Diagram for Student Management System using UML Tool

Time needed: 5 minutes.

Steps in creating Class Diagram for Student Management System is elaborated here.

  • Step 1: Familiarize Class Diagram Components

    Class Diagram Components – are used to create Class Diagram which were presented here. they should be familiarized before you build the Class Diagram.

    Class Name : The name of the class appears in the upper portion. Whether you’re talking about the classifier or an object, this portion is always essential.
    Class Attributes : The class’s attributes are found in the middle portion. Use this section to describe the class’s characteristics. When specifying a specific instance of a class, this is only required.
    Class operations : are included in the bottom part (methods). Each action has its own line when displayed in a list format. The operations are the methods by which a class interacts with data.
    Class Connections : Depending on the access modifier, each class has a different level of access (visibility). The following are the access levels and the symbols that correlate to them:
    • Public (+)
    • Private (-)
    • Protected (#)
    • Package (~)
    • Derived (/)
    • Static (underlined)

    Each of these class diagram components shows the overall Class structure. Emphasizing the System’s structure would be much easier by using these Class 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 Student Management System for school, then your users would be the Staff, Admin and the students. You may ask them of the common activities that they do when doing task in student management. These information will help you in proceeding with the next step.

  • Step 3: Analyze the activities included

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

    The gathered information from the targeted users are very useful in creating an class diagram. You just need to evaluate these data and pick the useful classes. Then you’re ready for the next step.

  • Step 4: Plot the Class Diagram

    To plot the class diagram you will need the class name, its attributes, methods, and their access (visibility). You will base the diagram from the evaluated information to have the exact Class Diagram.

    To plot your Class diagram, you need to place first the classes and their characteristics.

    Then place the visibility of the class’ attributes. You will declare their visibility into the project to know their function.

    Finally, put the connections or relation of a class to the other classes to make sure they are working to produce the desired outcome.


It is essential for you to know the diagrams used to design and develop the student management system. That is because you cannot perfectly create a fully-functional system without it. But if you create this class diagram, you will know the possible classes 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 class diagram can be used to model the system’s structure. The system main concept is captured in a class diagram, which describes the flow from one system to the next. By completing the Class Diagrams per module or per processes, you will easily achieve your desired system. Check out our Related and Recommended Articles for more Learnings and Information.
