Using the functional dependencies of Exercise 7.11, compute the canonical cover Fc.
Answer to relevant QuestionsConsider the algorithm in figure to compute α+. Show that this algorithm is more efficient than the one presented in Figure (Section 7.3.3) and that it computes α+ correctly.Show that it is possible to ensure that a dependency-preserving decomposition into 3NF is a loss less-join decomposition by guaranteeing that at least one schema contains a candidate key for the schema being decomposed.A functional dependency α → β is called a partial dependency if there is a proper subset γ of α such that γ → β.We says that β is partially dependent on α.
