1. Find all candidate keys for relation R(ABCDE). Following functional depen- dencies exist in relation R: A + B, BC + E, ED + A 2. Given relation R(ABCDEF) and following functional dependencies: F = {A + BC, E + ABC, F + CD,CD → BEF} Determine all candidate keys! 3. Given two sets of functional dependencies: • A + B, A + C,CD + E, B + D • A + BC, AD + E, DB + B, A + D
