Students begin by reviewing the university's course catalog and class schedule booklets to identify the courses they wish to take for the upcoming semester. They consider their academic requirements, interests, and scheduling preferences when selecting courses. Students verify if the courses they plan to register for have any prerequisites or restrictions. Prerequisites may include completing specific courses or achieving certain academic standing, while restrictions may include enrollment limits or restrictions based on major or class level. Students create a tentative schedule by selecting specific class sections, considering factors such as class times, locations, and instructor preferences. They use the scheduling software provided by the university to assist with planning. Students then log in to the university's online student portal or registration system to access the registration interface. This system allows students to view available class sections, add or drop courses, and make changes to their schedule. Using the registration system, students enter the CRNs $($Course Reference Numbers$)$ or search for courses by name, department, or keyword. They select the specific class sections they wish to register for and add them to their schedule. As students add courses to their schedule, they check for availability and conflicts with other classes or commitments. The registration system typically displays real$-$time information about seat availability, waitlists, and scheduling conflicts. Once students have finalized their course selections and schedule, they confirm their registration within the system. Some universities may require students to review and accept registration policies, tuition fees, and other terms and conditions before completing the registration process. After confirming registration, students may be required to pay tuition and fees associated with the courses they have registered for. Payment options and deadlines are typically provided by the university's bursar or student financial services office. Upon successful registration and payment, students receive confirmation of their class schedule and enrollment status. This confirmation is available immediately through the registration system and sent via email. Throughout the registration period, students monitor their class schedule and enrollment status for any changes, including seat openings, waitlist notifications, or course cancellations. They may make adjustments to their schedule as needed. Once the registration process is complete, students attend classes according to their schedule and begin the semester's coursework.Create $($using draw.io$)$:$(1)$ A current state UML activity diagram $(2)$ A future state UML activity diagram $(3)$ A future state Crow's Foot EER data model
