Each question will have at least one functional dependency but may have more. Based on the information provided in each question, first determine the functional dependencies. Once dependencies are created, determine the relations. For each relation, determine all the attributes (fields) and specify which attribute or attributes will make up the primary key. Once you determine the relations and attributes make sure that the final relations are in least 3NF.

Tip: The relations name in a singular noun and the primary key is underlined. Each question is worth 3 points unless otherwise indicated.

Read through the scenario completely and carefully before creating the relational model for questions 1 to 5. Suppose we have the following requirements to create a university database.

 

1. The university keeps track of each student’s first name, last name, id number, major, phone, start semester, start year, and date of birth.

2. Each academic department is described by department name, department code, office number, office phone, and college.

3. The university keeps track of each professor’s name, id number, phone, salary, hire date and department they work in.

4. Each course has a course name, description, course number, number of credit hours per course, level (undergraduate or graduate), and department code.

5. The same courses are offered every semester. Each course offering has a course number, section number, professor’s id, and the semester and year the course is being taught in. The section number distinguishes different sections of the same course that are taught in the same semester.

HINT: An example of a course is CIS 380 A. CIS 380 is the course number and A is the section.

 

Additional Questions.

6. Part (PartNo, Description, (VendorNum, VendorName, Address, UnitCost))

7. Employee (EmployeeID, EmployeeName, SkillCode, SkillTitle, SkillType)

8. (4 points) Ticket (StudentID, FirstName, LastName, PhoneNo, StateLicense, StateLicenseNo, (TicketNum, Date, TicketCode, Fine))

HINT 1: You cannot determine a state license number based off knowing the state license.
HINT 2: You can determine the fine amount based off knowing the ticket code.
