Use Case Description versus Activity Diagram” Please respond to the following:
•Compare a use case description and an activity diagram. Devise a scenario in which you would use a case description, and devise a scenario in which you would use an activity diagram.
•Consider a system needed to store information about computers in a computer lab at a university, such as the features and location of each computer. Ascertain the domain classes that might be included within the domain model. Discuss whether or not you believe an entity-relationship diagram (ERD) would be a suitable model.
“Comparing Approaches” Please respond to the following:
•Outline the primary ways in which the traditional approach to modeling a use case differs from an object-oriented approach. Develop a scenario in which you would use the traditional approach over the object-oriented approach, and explain your reasons why.
•Analyze the difference between a use case and a scenario. Give a specific example of a use case with at least two (2) possible scenarios.
“User Interfaces” Please respond to the following:
•Consider at least two (2) software products that you use or have used in the past. Provide at least two (2) examples in which ease of learning conflicted with ease of use. Propose a solution to the conflicts that you have indicated. Justify your response.
•Examine at least two (2) instances where security conflicted with ease of use. Propose a solution to the conflicts you have indicated. Provide a rationale for your response.
