This assignment uses the Football Tipping Case Study contained in a separate document. Carefully read the case study.  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 your own words.

Question 1: Sequence Diagram  

          Define sequence diagram in UML. Draw sequence diagram using the ‘use case 1’ for operations 1,2,3 and 4.

Question 2  Communication Diagram

 Describe the basic differences of communication diagram with sequence diagram. Using ‘use case 1’ draw communication diagrams for operations 5,6 and 7.

Question 3. Class diagram

Create a design class diagram from the seven interaction diagrams created in Question1 and 2. Only show class diagram features that can be derived from the objects shown in your diagrams.

Question 4. Discuss Grasp Patterns   

Discuss the following Grasp patterns that have been used to construct the interaction diagrams in your solution –

• Expert
• Creator
• Low Coupling
• High Cohesion
• Controller

Discuss one good application of the pattern from the interaction diagrams under a heading for each pattern. Submit your discussion with the pattern heading, followed by your 3 – 5 lines of discussion.

Online submission via Turnitin is required for this assignment.

Rationale

This assignment is assesses your object modelling concept and understanding of the design techniques and processes contained in this subject. It has been designed to ensure that you are engaging with the subject content on a regular basis.

More specifically it seeks to assess your ability to:

–  create class diagrams and dynamic models (sequence, collaboration, state and activity diagrams) with UML notation

–  compare the syntax, semantics and pragmatics of UML.

–  design the system design with different design patterns; and

– perform modelling of various aspects of systems of a quality that would make it useful in a system development project.

Marking criteria

The following marking sheet will be used to assess students’ submissions. Please check that you have met all the criteria before you submit your assignment. The detail marking rubric will be supplied into the resources section of subject Interact site prior to the session –

Case Study
As a member of the state Committee for common childhood diseases, you have been asked to help formulate a policy on the management of chronic otitis media with effusion (also known as glue ear). Glue ear is the most common cause of hearing problems in childhood and can lead to delayed language development. Many treatment choices exited, including grommets (pressure-equalizing tympanostomy tubes), analgesics, antibiotics, vaccinations and hearing aids. However, since glue ear usually resolves spontaneously, you might also choose to do nothing, at least initially. Given these various treatment options, should your committee recommend monitoring for hearing loss, treatment with grommet insertion, or the use of hearing aids? For example, tympanometry, which measures the eardrum ‘ability to move, can be used as a monitoring tool, though an audiogram is needed to confirm the degree of any hearing loss.
1. How do you proceed with formulating a recommendation?
2. How can you systematically approach such a decision?
