Component Diagram for Online Examination System

The component diagram of online examination system is used to show how the system’s parts work together to make it operate correctly. This component diagram shows how the software’s parts are organized and how they depend on each other. It gives a high-level look at the parts of the online examination system.

Components of an online examination system component diagram can be part of software or hardware. They could be a database, a user interface, or something else that helps the online examination system work.

What is an Online Examination System?

An online examination system is a computer-based test system that may be used to conduct computer-based tests online. This test system doesn’t use as many resources and doesn’t need question papers or answer scripts. It also doesn’t need to schedule exam rooms, coordinate invigilators, or do other things.

This online examination system gives the examination procedure more flexibility and security. Once all of the questions have been submitted, the system can shuffle and assign questions to students in different orders. This reduces the possibility of cheating.

The purpose of the online examination approach is to evaluate students’ knowledge of the subject. In comparison to traditional pen-and-paper testing, this method minimizes logistical problems and disadvantages. Students are not required to gather in the classroom for the exam.

These statements were collected as the information concepts in developing the system UML diagrams. The concept formulated will be applied to the component diagram illustration.

What is Online Examination System Component Diagram in UML?

A component diagram in the (UML) Unified Modeling Language shows how parts are wired together to explain the parts of examination systems. They are used to show the structure of any kind of system.

The UML component diagram shows how an examination system will be made up of and the set of deployable components, such as dynamic-link library (DLL) files, executable files, or web services. Using well-defined interfaces, these parts communicate with each other and keep their internal details hidden from each other and the outside world.

The Component Diagram for Online Examination System

This component diagram of online examination system is the illustration of the components of every hardware and software node. The component diagram below is a detailed illustration of the Deployment Diagram for Online Examination System.

This component diagram shows the structure of the examination system, which consists of the software components and their interfaces, and how they work together. You can use component diagrams to show how software systems work at a high level, or you can use them to show how each component works at a lower level, like in a package.

Online Examination System Component Diagram (Explanation)

The Online Examination System UML component diagram explains the sketch of the required software and hardware components and the dependencies between them. These components are labeled to clarify their part in the system’s operation. They were represented by symbols that explain their function and role in the overall online examination system operation. The dependencies on each component are explained through the lines and arrows drawn in the diagram.

The component diagram of online examination system has 6 components which are the examinee’s access, exam information, subject information, exam contents, information database, and the result database. This diagram shows several interfaces that are provided and required. The required interfaces (components) are the exam information and the result database. They were then provided by the interface they were connected to.

Characteristics of Component Diagram:

  • In component-based development, they are used to describe systems that have a service-oriented architecture.
  • Shows how the code itself looks.
  • It can be used to focus on the relationship between the parts while hiding the specifics.
  • Help stakeholders understand how the system being built works and how it will be used.

Benefits of using Component Diagram

As complicated as it looks, the component diagram is very important when you’re building your system because it shows how everything works together. Here are the benefits of designing the online examination system component diagram:

  • Imagine how the system looks in real life.
  • Pay attention to the system’s parts and how they work together.
  • Pay attention to how the service behaves when it comes to the interface.

Steps in Developing Component Diagram:

Time needed: 10 minutes

Here are the steps in developing the online examination system component diagram.

  • Finalize the Function and Processes of the Software

    The first step in developing the component diagram is finalizing the processes and functions of the software. This activity will help programmers analyze what are the things needed to complete the online examination system process. Then the finalized processes or functions will be the base concept in designing the system’s component diagram.

  • Put the Components included

    A component is a piece of the system that makes sense in terms of logic. It’s a little more abstract than classes. There are tabs or the word “Component” written on top of the name of the component to help you tell it apart from a class.

    The component symbol is used for a person or thing that needs to do a stereotype function. It gives and takes behavior through interfaces, as well as through other parts. Components can be grouped into a node or another component and can be only one component.

  • Add the Dependencies (Ports and interfaces)

    A dependency is a relationship in which one component needs the information and services of another component, but not always the other way around. To show that one component is relying on another, you should make a connection.

    The component’s port is a feature that indicates where the component and its environment meet. In this picture, ports are shown in the form of small squares on the sides of classifiers. It is created when one thing is needed for another thing to work. There is an “include” statement in the makefile for the component that is dependent on the other component.

    Interfaces show how components are wired together and how they work together. When a component needs a certain interface, the assembly connector lets you connect it to another component that already has that interface. It looks like a semi-circle and a line.

    A component list contains the set of interfaces that a component can use or realize. Components also need interfaces to do their job. It is part of a system that protects the things inside. They are the parts of a system that make sense and play a big part in how a system works.

Conclusion

You need to know the diagrams used to design and develop the Online Examination System. This method is to perfectly create a fully-functional system without unwanted errors and avoid mistakes in development. A component diagram will help you know the components of software and hardware that the project should possess. Not only that, you will find out the needed consideration for the software to work perfectly.

Component diagrams show how a system is put together. During the design phase, software artifacts (classes, interfaces, etc.) of a system are put together into different groups based on how they work together. Now, these groups of things are called parts. Check out our Related and Recommended Articles for more Learning and Information.
