Suppose that you have the following requirements for a university database that is used to keep
track of students’ transcripts: The university keeps track of the students name, student number,
current address, phone, birth date, gender, class (‘freshman’, ‘sophomore’, … , ‘graduate’),
major department. Each department is described by a name, department code, office number
and college. Each student can study more than a course that has a course name, description,
course code, number of semester hours, level, and offering department. Finally, a grade record
refers to a student, a particular course, and the total degree of all courses he has studied.
Design the ERD for this database and implement the schema for this database application using
the suitable SQL commands. First show all the functional dependencies that should hold among
the database attributes. Then design relation schemas for the database that are each in 3NF with
clarifying the conditions you have applied to reach the 3NF. Specify the key attributes of each
relation. Note make any appropriate assumptions to render the specification complete.
