- Question # 2: Draw an ER of following scenario Vehicle registration System has three types of users Admin, Applicant and Bank Employee. There is only one Admin in this system. The system is intended to do two major tasks i.e. registration, verification, tax/token fee payments and transfers of vehicles and keeping track of vehicles insurance. Different types of users have different privileges to the system, whereas admin has the maximum access to the system. It also keep track of every enrolled vehicles and can generate the reports for admin. In our system applicant fills the registration form as per its required specification and submits it to system, where its data is shifted on system by profiling it, here system will check the applicant’s registered information in order to abide by the redundancy factor of data then the application of end user is submitted in accordance to its feasibility of requirements likewise vehicle registration or…Read the following scenario describing the use case "Marking assessments on Edugate system", then create a UML Activity Diagram for the scenario: "This use case begins when a student submits a solution to an assignment. The instructor logs into the Edugate system. The system verifies the entered password and prompts the instructor to re- enter his password if the password was incorrect up to three attempts. The instructor selects the class from the list of classes he/she teaches this semester. The instructor selects Mark Assignment option from the class main interface. If the student failed to submit a solution, the instructor sets the mark to zero, otherwise the instructor views the submitted solution, then enters the mark, then selects save. Finally, the system saves the mark".O d. Methodology Things can be documented at the Object Oriented approach by: O a. Class diagram O b. Data stores O c. Use case diagram O d. ERD
