UML diagrams for the Student Management System. Following are the different UML diagrams like Components, Activity, Use Case, and Sequence diagrams of the Student Management System.
With the help of these diagrams, one can get a better understanding of the project.
UML Diagram for Student Management System
In this article, we have put together the structural UML diagrams i.e. component diagrams, and three types of behavioural UML diagrams i.e. Activity, Sequence, and Use Case diagrams for the Student Management System. We have also covered this project’s data flow diagram (DFD).
This web application is developed to provide an online medium where the Admin can manage the record of students in the university, college, School, or any institute.
Component diagram for Student Management System
Component diagrams are essentially class diagrams that focus on a system’s components that are often used to model the static implementation view of a system. The components are connected by lines representing relationships within the systems.
In the diagram, it can be seen that there are components namely students, courses, add fees, faculty, and subject. There are two users that can access the system. One is the admin and the other is the User.
Admin can manage any details related to the students, faculty, courses, and subject in the system. Admin will be allowed to add/remove any student and faculty member. Admin will be responsible for maintaining the databases.
Admin can add students, faculty, and new admin using the administration module.
Users can get the Attendance, subjects, mark sheet, etc.
Activity diagram for Student Management System
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 will be responsible for maintaining the system and also, keeping a check on faculty members, courses created for classes, information about courses, subjects, attendance, results, fee details, etc.
Admin can View and Add/EDIT/Delete new faculty, new admin, and students into the system. Admin can View and Add/EDIT/Delete new subjects and courses into the system. Admin can manage subjects, students and faculty members.
Whereas, User members can manage and maintain their profile. Users can access mark sheets, results, attendance, subject, and fee details.
Sequence diagram for Student Management System
Sequence diagrams in UML are used to illustrate the sequence of messages between objects in an interaction. A sequence diagram consists of a group of objects that are represented by lifelines and the messages that they exchange overtime during the interaction.
Admin can course with all the information like subjects, faculty, days, etc. Admin can View and Add new faculty and student into the system. Admin can View and Add new subjects into the system. Admin can manage subjects, students and faculty members. Admin can assign faculties to a particular subject accordingly.
Users can access the Attendance and other information anytime. Students can view subject details, fee details, attendance details, etc. Students can view results, subject details, and fee details.
Use Case Diagram for Student Management System
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. You can see where each actor is involved in the entire process.
Admin, every use case is accessible to the admin except where admin can add/delete/update any detail, whereas, a user can access to view fee, subject and attendance details. User can access their profile, and login/logout use cases.
DFD Diagram for Student Management System
A data flow diagram represents the flow of information for any process or system. 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.
Admin will manage the overall application. The critical objective is to have an application where students’ information can be maintained and updated accordingly. This project has all the necessary functionality from adding and deleting courses, faculty, students, and subjects from the system.
Admin and User can manage their “MY Profile” and can change the password. There is Login/Logout functionality. On the other hand, users can access attendance and other details.
