Chapter 16 MULTIPLE CHOICE 1. Integrating separate REA diagrams developed for individual transaction cycles into a single, comprehensive enterprise-wide data model a) is possible. b) requires understanding what the cardinalities in each separate diagram reveal about the organization’s business policies and activities. c) provides a single comprehensive enterprise-wide model of the organization. d) all of the above are true. 2. An integrated REA diagram merges multiple copies of _______ and ______entities but retains multiple copies of ______ entities. a) Resource, event, agent b) Relationship, economic, accounting c) Resource, economic, agent d) Relationship, event, accounting 3. 4. An integrated REA diagram contains multiple copies of a) Accounts b) Agents c) Events d) Resource 5. 6. An integrated REA diagram merges multiple copies of some entities in order to a) Minimize the repetition of agent entities. b) Maximize the legibility of the comprehensive REA diagram by avoiding the need to have relationship lines cross one another. c) Both A and B are true. d) Both A and B are false. 7. 8. Combining REA diagrams for individual transaction cycles into a single, enterprise-wide model adds two more rules to the three basic principles for drawing REA diagrams. Which of the following is not one of those two new rules? a) Every resource must be linked to at least one event that increments that resource and to at least one event that decrements that resource. b) If a specific event can be linked to more than one other type of event, but cannot be linked simultaneously to all of those other events, then the minimum cardinality between that event and every other event with which it may be associated must be 0. c) If a specific event can be linked to more than one other type of event, but cannot be linked simultaneously to all of those other events, then the maximum cardinality between that event and every other event with which it may be associated must be 0. d) None of the above 9.
