1. Define third normal form. What types of problems would you find in tables that are not in third normal form?
2. Define fourth normal form. What types of problems would you find in tables that are not in fourth normal form?
3. Define interrelation constraint and give one example of such a constraint. How are interrelation constraints addressed?
4. Consider a Student table containing StudentNum, StudentName, students StudentMajor, students AdvisorNum,

students AdvisorName, students AdvisorOfficeNum, students AdvisorPhone, students NumCredits, and stu- dents Category (freshman, sophomore, and so on). List the functional dependencies that exist, along with the assumptions that would support those dependencies.

5. Convert the following table to an equivalent collection of tables that are in third normal form. This table contains information about patients of a dentist. Each patient belongs to a household. Patient (HouseholdNum, HouseholdName, Street, City, State, PostalCode, Balance, PatientNum, PatientName, (ServiceCode, Description, Fee, Date)) The following dependencies exist in the Patient table: PatientNum HouseholdNum, HouseholdName, Street, City, State, PostalCode, Balance, PatientName HouseholdNum HouseholdName, Street, City, State, PostalCode, Balance ServiceCode Description, Fee PatientNum, ServiceCode Date

6. Using your knowledge of the college environment, determine the functional dependencies that exist in the fol- lowing table. After determining the functional dependencies, convert this table to an equivalent collection of tables that are in third normal form. Student (StudentNum, StudentName, NumCredits, AdvisorNum, AdvisorName, DeptNum, DeptName, (CourseNum, Description, Term, Grade))
