Use Case diagram of the system: A use case diagram is a powerful tool in software engineering and system design, providing a visual representation of the various interactions between different actors and a system.The Actors are: ?Student: The "Student" actor represents individuals enrolled in the university. In the diagram, the student is associated with several use cases, including accessing subjects, logging into the system, sending and receiving messages, and uploading assignments. These actions collectively capture the essential activities a student can perform within the university system. ?Doctor (Professor): The "Doctor" or "Professor" actor embodies the teaching staff at the university.?IT (Admin): The "IT" or "Admin" actor represents the administrative staff responsible for system maintenance and problem-solving. Admins can solve problems related to the system and access subject-related information. Their role is crucial in ensuring the overall functionality and health of the university system. ?Assistant Teaching: The "Assistant Teaching" actor signifies teaching assistants who play a supportive role in managing subjects, messages, teaching materials, and logins.?University: The "University" actor serves as an overarching entity coordinating various activities and managing resources within the system. This actor is associated with high-level use cases such as performing university actions, managing resources, and coordinating activities. The "University" actor interacts with other actors, symbolizing its central role in ensuring the effective operation of the entire university system.

Use Case diagram of the system:
A use case diagram is a powerful tool in software engineering and system design, providing a visual representation of the various interactions between different actors and a system. In the context of a university system, the diagram you provided illustrates the roles and functionalities of key actors within the system, offering insights into how these actors interact with the system and each other. The Actors are:
Student:
The "Student" actor represents individuals enrolled in the university. In the diagram, the student is associated with several use cases, including accessing subjects, logging into the system, sending and receiving messages, and uploading assignments. These actions collectively capture the essential activities a student can perform within the university system.
Doctor (Professor):
The "Doctor" or "Professor" actor embodies the teaching staff at the university. Professors are equipped with functionalities such as logging into the system, uploading teaching materials, exchanging messages, and accessing subject-related information. These capabilities reflect the academic responsibilities and interactions professors have within the system.
IT (Admin):
The "IT" or "Admin" actor represents the administrative staff responsible for system maintenance and problem-solving. Admins can solve problems related to the system and access subject-related information. Their role is crucial in ensuring the overall functionality and health of the university system.
Assistant Teaching:
The "Assistant Teaching" actor signifies teaching assistants who play a supportive role in managing subjects, messages, teaching materials, and logins. This actor is associated with various use cases reflecting the diverse responsibilities of teaching assistants within the university system.
University:
The "University" actor serves as an overarching entity coordinating various activities and managing resources within the system. This actor is associated with high-level use cases such as performing university actions, managing resources, and coordinating activities. The "University" actor interacts with other actors, symbolizing its central role in ensuring the effective operation of the entire university system.
Students can access information related to subjects, log into the system, Send and receive messages, and submit assignments.
Professors can log into the system, upload teaching materials, send and receive messages, and access information related to subjects, solve problems related to the system, and access information related to subjects.
Teaching Assistants can access information related to subjects, send, and receive messages, upload teaching materials, and log into the system.
The university can execute overarching actions, administer system resources, and coordinate activities with teaching assistants, admins, professors, and students.
Relationships:
The arrows between actors and use cases denote relationships or interactions. These relationships highlight the connections and dependencies between actors and the functionalities they can perform.
For example, the arrow from "University" to "Teaching Assistant" labeled "Coordinate Activities" indicates that the university coordinates activities with teaching assistants. This interaction could involve planning and organizing various educational or administrative activities within the university system.
