Introduction

The development of robust and comprehensive system models such as sequence diagrams is essential for understanding interactions within software applications. These diagrams visually represent how objects or components communicate over time to accomplish specific functionalities. In this paper, we explore detailed sequence diagrams for various use cases in an educational management system, including user login, admin operations like adding students, managing comments, managing classes, rubrics, faculty, and teams. Each diagram offers insights into the step-by-step processes involved, ensuring clarity in design and implementation.

Use Case 1: User Login

In the user login sequence, the actor—either an Admin, Faculty, or Student—initiates the process by clicking the login link or entering the login URL into a web browser. The system responds by displaying the login page. Once credentials are entered and the login button is clicked, the system retrieves a user list based on the role provided. The system then checks if the username exists within this list. If the username is found, it compares the entered password against stored passwords. Successful validation leads to starting an authenticated session, retrieving the faculty list, and displaying the faculty view page as the user's landing page. Else, appropriate error messages are displayed for invalid username or password, or options for recovering usernames are provided.

The sequence diagram for this use case depicts actors interacting with the system, with messages flowing sequentially as per the described steps, including validation, session initiation, and redirection.

Use Case 2: Admin Adds Student

This use case involves an admin managing student details. The admin begins by selecting the "Students" tab on the admin homepage, which triggers retrieval of the student list and displaying the student view page. Clicking on "New Student" brings up an "Add Student" form where the admin enters student data, including selecting the institute from a dropdown. Upon clicking "Save," the system validates the input, and if valid, saves the data to the database, displaying a success message. These interactions are represented in the sequence diagram, showing the admin's actions, system validations, database operations, and feedback messages.

Use Case 3: Making Comments on Assessment

Students can make comments on peer assessments. After clicking "Make a Comment," the system verifies the session and displays a comment input form. The student inputs a comment, which upon clicking "Save," undergoes validation for length and content. If valid, the comment is sent to the instructor for approval, with status updates reflected via a state machine diagram illustrating different approval states, disapproval, revision, and display.

Use Case 4: View and Manage Classes

Admin users select a school and faculty, prompting the system to display relevant classes. The admin can then choose to edit class details, which involves displaying a form, receiving input, and updating stored information. Similarly, updating courses for a class involves selecting the class, modifying course list, and saving changes. The sequence diagrams for these interactions emphasize CRUD operations, validation, and real-time updates.

Use Case 5: Manage Rubrics

Rubrics management includes selecting a school and faculty, editing existing rubrics, and adding new ones. The sequence diagram depicts the process of retrieving rubric lists, presenting editing forms, validating input, saving changes, and displaying confirmation messages. Removing rubrics is also covered, with notifications sent post-update.

Use Case 6: Manage Faculty

Faculty management involves login validation, executing CRUD operations on faculty records, and logging out. The sequence diagram details the interactions between the user, system validation processes, data storage, and session management, ensuring secure and efficient operations.

Use Case 7: Manage Teams

For team management, the admin selects classes, views current teams, updates team memberships, or creates new teams. These functions involve selecting classes, showing team lists, editing member lists, and confirming actions with success messages, represented clearly in respective sequence diagrams.

Conclusion

Analyzing these use cases through sequence diagrams highlights the intricate communication protocols between users and the system components. Such diagrams aid developers and stakeholders in understanding operational flows, pinpointing potential issues, and ensuring that the system's architecture aligns with functional requirements. The detailed visualizations serve as foundational references for implementing reliable and scalable software solutions in educational management contexts.
