Yоu аre designing а dаtabase fоr an elite cybersecurity training camp. The relatiоn is: Session(Student, Subject, Instructor) The Rules (Functional Dependencies): Rule A: For any given Subject, a Student is assigned to exactly one Instructor. (e.g., If John studies "Ethical Hacking", he has exactly one instructor for it). Rule B: An Instructor is a specialist who teaches only one Subject. (e.g., If Dr. Smith teaches "Ethical Hacking", she cannot teach "Cryptography"). Rule C: A Subject can have multiple instructors. Rule D: A Student can take multiple subjects. The Sample Data Student Subject Instructor Alice Network Sec Prof. X Alice Crypto Prof. Y Bob Network Sec Prof. Z Bob Crypto Prof. Y The Question Identify the Candidate Keys of the relation Session. What is the highest Normal Form this table currently satisfies (1NF, 2NF, 3NF, or BCNF)? Decompose the table into BCNF (if it isn't already). After decomposition, demonstrate if we have lost any constraints (Dependency Preservation). Can we enforce "Rule A" purely using the Primary Keys of the new tables?
