repeating group.
relationship.
Question 3. A collection of entities that share common properties or characteristics best defines
entity type.
entity instance.
entity occurrence.
entity collection.
data set.
Question 4. An attribute (or combination of attributes) that uniquely identifies each instance of an entity type defines
data element occurrence.

Question 8. During which of the following steps will you bring the current phase to a close, prepare a report and presentation to management concerning continuation of the project, and get ready to move the project into design?
Designing the human interface
Requirements determination
Project initiation and planning
Alternative generation and selection
Requirements structuring
Question 9. Enumerating different potential implementation environments that could be used to deliver the different sets of capabilities occurs during the
requirements structuring step of the analysis phase.
alternative generation and selection step of the analysis phase.
testing step of the implementation and operation phase.
