Question
Relation R(A,B,C,D,E) has {AB`->` C, C`->` D,B`->` EA}
FUNCTIONAL DEPENDENCY Find the candidate key of the relation.Solution
B closure contain all (A,B,C,D,E) so it will be the candidate key of the relation.
Statements: B ≤ C < E; D ≤ F ≤ G; E = D; A > B
Conclusions:
(i) E ≥ G
(ii) A < E
(iii) B ≤ G
(iv) C < F
