Component Diagram of Library Management System

Component Diagram of Library Management System

The component diagram of library management system in UML is used to show how the library system parts cooperate in delivering a well-done function. This component diagram shows how the software’s components are organized and how they depend on each other. It gives a high-level look at the parts of the library management system.

Components of a library management system component diagram can compose of software or hardware. They could be a database, a user interface, or something else that helps the library management system work.

Component Diagram of Library Management System Description

A library management system is software that can be used to manage all the tasks of a library, like how many members can come in and out. This tool keeps track of new books and the books that members have checked out. They can also be monitored when the borrowing session is due. This system does all of your library’s work for you.

Library management systems keep track of the movement of books and the individuals who utilize the library. The software solution is made to meet the needs of the system, the users, the content of the operation, and the activity that will be done.

What is Library Management System Component Diagram in UML?

A component diagram in the (UML) Unified Modeling Language shows how parts are wired together to create bigger parts of the library system. They are used to show the structure of the library management system.

The UML component diagram shows how a software system will be made up of a 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 of Library Management System

This component diagram of library management system is the illustration of the components of every hardware and software node. The component diagram below is a detailed illustration of the library management system deployment diagram.

This component diagram shows the structure of the library 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 specific area of a function or part of the system.

Library Management System Component Diagram (Explanation)

The Library Management 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 library management operation.

The component diagram of library management system has 5 components which are book database, transaction database, output, online search, and the user. The component “output” is the required interface which is dependent on the provided book database component. The included components were just based on the main function of the system.

The dependencies on each component are explained through the lines and arrows drawn in the diagram. This design can be modified or can be innovated to achieve the required functions of the said system.

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 library management component diagram:

  • Describes 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 for Library Management System

Time needed: 10 minutes

Here are the steps in developing the library management 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 library management 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. In order 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.


You need to know the diagrams used to design and develop the Library Management 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.
