UML diagrams for the Library Management project, following are different UML diagrams explaining Components, Activity, Use Case, and Sequence diagrams of the Library Management.
The Library Management application will help to manage the issuing of books, students, etc. It allows the library owner to manage the day-to-day process of a book issuing conveniently.
UML Diagram for Library Management System
We’ve compiled structural UML diagrams i.e. component diagrams, and three types of behavioural UML diagrams i.e. Activity, Sequence, Component, and Use Case diagrams for the Library Management Project.
The objective of the library management system is to design a web application in java that can manage a library. An easy and user-friendly interface that is easy to operate and understand for the students as well as for librarians. An Easy platform to manage books and the records of books like the issued book and the student records.
Component diagram for Library Management Project
The diagram below shows the structural relations between components in a Library Management system. The connected components by lines represent relationships within the systems. In the diagram, it can be seen that there are components namely product, order, student, and account.
It shows how the student component connects to the other components while using the system. Everything from the account details to product booking to payment flow can be seen in the component diagram.
Admin can ADD/EDIT/DELETE the books in the library. Admin can ADD/EDIT/DELETE users or students. Admin can check the available books and issue books records. Admin can issue a book to the new user after the successful authentication. Whereas, User can check the issued books.
Activity diagram for Library Management Project
Activity diagrams in UML display the functionalities of various activities and flow in management processes and software systems. The flow in the activity diagram can be sequential, branched, or concurrent.
Admin can view the list of students. Admin can manage the category of books and can update all book detail. Admin can view issue history and detail. Admin can manage students and library from one place.
Students can view specific books issued to them. Students can log in and view the issued books record.
Sequence diagram for Library Management Project
Sequence diagrams in UML are used to better understand how tasks within a project will function, overlap, and move between objects or components. Sequence diagrams display step-by-step interactions between objects and the order in which those interactions occur.
Admin can ADD/EDIT/DELETE the books in the library. Admin can ADD/EDIT/DELETE users or students. Admin can check the available books and issue books records. Admin can issue a book to the new user after the successful authentication. Whereas, User can check the issued books.
On the other hand, users (students) can register, log in to the system, view issued books, and manage their profiles.
Use Case Diagram for Library Management Project
A UML use case diagram can create a broad, high-level view of the relationship between use cases, actors involved, and systems being performed.
As you can see from the examples below, use cases are represented by oval shapes, and the lines then show at which point an actor/user participates and interacts with their corresponding use case. We can see where each actor is involved in the entire process.
For example, in this project, Admin can add books. issue books to users whereas users(students) can view issued books record after logging in to the system.
DFD Diagram for Library Management Project
A DFD maps out the flow of information for any process or system. It gives a basic overview of the whole system or process being analyzed. It shows the system with its relationship to external entities. Here, we can see how the users and the process flow work in a system.
Initially, Admin and Student must be logged in to the system. Upon logging in, both Admin and Student will land on the home page where they can manage their profiles, view books, issue books, view issued books, etc.
Admin manages the issuing history. Students can also view their issued book records and manage their profiles on the system.
