PLEASE ANSWER FULLY AND COMPLETELY FOR THUMBS UP!! For Assignment #4, you will produce an original use case model using four ClickChart UML Notation shapes that pertain to use case modeling: Use Case; Actor; Container (for the system boundary); and Implementation, which should be used for the <> and <> associations. Per my demo, double-click on the Implementation shape and type either <> or <>. The Uses and Extends shapes provided by ClickChart should not be used because they do not have the << >> characters nor do they accept a text entry. Choose an original use case, i.e., not a use case model that (a) has been copied from a source on the Internet or (b) is very similar to the use cases shown as examples in the Chapter 6 slides. Advice on how to identify or choose an original use case, and on how to develop the use case model by asking yourself a few questions, is provided on the last Chapter 6 slide. (I also suggest listening to the part of the lecture where I discuss this slide.) While its recommended that you keep your use case model fairly simple, your model must satisfy the following requirements: At least three actors (but no more than five actors); At least five use cases; At least two <> and/or <> associations; and A system boundary that contains the use cases.
