The objective of this assignment is to design UML sequence diagrams for the key functionalities of the USCA online

course management system. The system should handle student enrollment, grading, and maintain details of professors

features. Follow these steps:

$1.$ Briefly describe the purpose and scope of the online course management system and provide an overview of the

key functionalities to be represented in the UML sequence diagrams.

$2.$ Identify and list the primary use cases that the online course management system should support. For each use

case, provide a brief description of the interactions between system actors $($professors$,$ students$)$ and the system

itself.

$3.$ Using Visual Paradigm, develop a UML sequence diagram for Student Enrollment; from course searching to

successful enrollment. Your diagram should show interactions between student, enrollment system, payment

system, and database.

$4.$ Using Visual Paradigm, Develop a UML sequence diagram for Grade Entry that describes the process of

professor entering grades for students. Should include interactions between professor, grading system interface,

grades database.

$5.$ Using Visual Paradigm, Develop a UML sequence diagram for Course Drop that shows the process of student

dropping a course they are enrolled in$.$ This will show interactions between the student, enrollment system,

notification system, database system.
