case tools will automatically perform many steps in the conversion of ER diagrams to relations. Which of the following is true about CASE conversions? Select one: a. It is better to allow these tools to work without human involvement to ensure complete accuracy of the conversion b. CASE tools are rare and specialized so all modelers must do their own conversions c. CASE tools cannot model complex data relationships and you must make choices between legitimate alternatives d. CASE tools were created because the conversion steps are too complex for most modelers Question 7 What are the steps involved in transforming an EER diagram into relations? Select one: a. first normal form, second normal form, third normal form, Boyce-Codd normal form, forth normal form, fifth normal form b. identify the entities, identify the attributes document the relationships, define associative entities, create supertypes/subtypes c. map regular entities, map weak entities, map binary entities, map associative entities, map unary relationships, map ternary (and n-ary) relationships, map supertype/subtype relationships d. remove repeating groups, select the primary key, remove transitive dependencies
