Assessment item 2 Short answer Value: 20% Due date: 28th Aug 2015 Return date: 18th Sept 2015 Submission method options Student should submit all assignments to turnitin.com   Task   This task uses the Case Study contained in a separate document. This document can be found in Assignment 2 Resources on Interact. Please read this case study carefully. You are required to answer the following questions based on the Case Study. It is expected that answers to the assignment questions be succinct and MUST be written in your own words.

Question 1. Prepare a use case diagram(s) for the case study. Must include Use case descriptions of the use case scenarios. (6 marks)

Question 2. Create a domain class diagram of the use case diagram(s) from Question 1. Only show the class diagrams derived from the use cases. Provide a detailed description of the domain class diagrams. (6 marks)

Question 3. Create a Systems sequence diagram (SSD) for the vehicle rental confirmation/booking use case. Provide a detailed description of your diagram. (6 marks)

Question 4. Create an Activity diagram that describes vehicle rental confirmation/booking use case scenario from Question 1. Provide a detailed description of your diagram, relating it back to the use case scenario. (6 marks)

Question 5. Create a State diagram of the vehicle rental confirmation/booking use case. Provide a detailed description. (6 marks)

Rationale This assessment tasks covers the fundamental concepts of object modeling, use cases, dynamic models and has been designed to ensure that you are

engaging with the subject content on a regular basis. More specifically it assess your ability to

• Apply the concepts of object orientation methodology (Learning outcome 1);

• Analyse system requirements to determine the use cases and domain model of the problem domain (Learning outcome 3);

• Create class diagrams and dynamic models with UML notations (Learning outcome 4);

• Compare the syntax, semantics and pragmatics of UML (Learning outcome 5);

• Perform modeling of various aspects of systems from a case study (Learning outcome 6).
