Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

Define trivial functional dependency.

πŸ’‘ Hint: Think about relationships where knowing one attribute gives no new information.

Question 2

Easy

What is a non-trivial functional dependency?

πŸ’‘ Hint: Consider examples where one attribute directly tells you something about another attribute.

Question 1

What is a trivial functional dependency?

  • A dependency providing new information
  • A dependency where B is a subset of A
  • A dependency with no relationship

πŸ’‘ Hint: Think about trivial mathematical truths.

Question 2

Is CourseID β†’ CourseTitle a trivial or non-trivial functional dependency?

  • True
  • False

πŸ’‘ Hint: Think about the information you gain when knowing one value.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a relation: StudentID, CourseID, InstructorName. Define two FDs. Classify them as trivial or non-trivial and explain your reasoning.

πŸ’‘ Hint: Evaluate the dependency to see if one attribute gives new information.

Question 2

Propose a database schema where understanding trivial and non-trivial dependencies would be required to normalize it properly. Discuss the implications.

πŸ’‘ Hint: Think of what relationships might overlap.
