Functional dependencies are a generalization of
-
Key dependencies.
-
Relation dependencies.
-
Database dependencies.
-
All of these.
-
None of these.
A
Correct answer
Explanation
Functional dependencies generalize the concept of key dependencies in database normalization theory. A key dependency is a special case where the determinant is a candidate key. Option B (Relation dependencies) and C (Database dependencies) are not standard theoretical concepts in this context. Option D cannot be correct because A is specifically right, and E is unnecessary since A is valid.
