Question 1 In a Jeopardy-style online quiz you are playing, the "answers to the bonus points question on normal forms are listed as the following: "All non-key columns must depend on the whole primary key." "A table with a simple primary key is automatically in this form. "This form does not eliminate all redundancies." To which normal form do these answers apply? Select one. Boyce-Codd normal form First normal form Third normal form Second normal form Question 2 Denormalization intentionally introduces redundancy by merging tables and therefore improves query performance. Which types of normal form tables does it result in? Select all that apply. First normal form Third normal form Fourth normal form Second normal form Boyce-Codd normal form Fifth normal form Question 3 When a table is in third normal form, which of these is true? Select one. OA single non-key column depends on one part of a composite primary key, whereas all other non-key columns depend on the other part of a composite primary key. All non-key columns depend on the whole primary key and on no other columns. A single non-key column depends on another non-key column, and all other non- key columns depend on the primary key. All non-key columns depend on the whole primary key but some also depend on other columns.
