Challenge Problems
Push your limits with advanced challenges
Given a database with student IDs, their courses, and scores, identify any functional dependencies. If a student can have multiple courses, analyze if the table is in BCNF and decompose it if necessary.
💡 Hint: Remember to list the functional dependencies clearly before determining the structural needs.
Analyze an Employee_Project table where each employee is assigned to multiple projects. Determine the functional dependencies and describe how you would ensure this table is in BCNF.
💡 Hint: Think through each functional dependency carefully to see what can uniquely identify each entry.
