OBJECTIVE: The fundamental objective in the assignment is to design a schema and raw an E-R diagram for the given application domain TASK: Create an ER Diagram for the following case study: The Motor Vehicle Branch administers driving tests and issues driver's licenses. Any person who wants a driver's license must first take a learner's exam at any Motor Vehicle Branch. If he fails the exam, he can take the exam again any time after a week of the failed exam date, at any branch. The system requirements are: - The driver identified by his SSN, and he has name, birth date, and address which contain from his city and phone number. - A driver takes exam in one branch, the exam date, exam score, and exam time must be recorded. Any driver must take at least one exam. And he must own at least one license. - Each branch identified by branch id, branch name, branch address. A branch may issue at least one license. we need to keep track on the issue date for each license issued. - Each license has license number, license class, and license expiry. Each license issued by one and only one branch and it owned by one and only one driver. Identify the relationship type, the participating entity types, and the attributes of each entity type, the primary key, the cardinality ratio, and participation constraints. Make any assumption you need. 1. Draw an ER diagram for that schema. (4 x 1 = 4 Marks) 2. Specify key attributes of each entity type 1 Mark Copying another person's words or work and pretend that they are your own is called PLAGIARISM. If you plagiarized, you will get zero mark for the assignment
