This assignment does not require any coding. You can draw Use Case models by hand, or by using any software tool of your choosing. Part 1: Design a UML Use Case model to specify the code you developed in the previous assignment. Part 2: Design a UML Use Case model for a complete Battle Ship game. You can use a specific Battle Ship game or use a hypothetical one as a reference. Your Use Case model should contain at least 10 Use Cases and demonstrate all Use Case Model elements, such as <> and <>. And, chose any two Use Cases and create a Use Case scenario. The Use Case Scenario should define the interactions between the User and the System, and define any alternative or exceptional scenarios. Evaluation Criteria: Correct: Proper use of modeling notation, correct identification of key system use cases.

Consistent: Are the different use cases consistent with each other?

Unambiguous: Is the use case model clear? Are there any ambiguities, or aspects that can have multiple interpretations?

Complete: Does the model cover in sufficient depth the battle ship game?
