ITECH7201 Software Engineering: Analysis and Design
You are required to design and develop a small Java console application. Completion of this assignment requires an understanding of:
- Analysis and design techniques, including development of use cases and UML diagrams – specifically, use case diagrams, class diagrams and sequence diagrams
- Object-oriented programming, focusing on polymorphism and the use of interfaces
Timelines and Expectations
Percentage Value of Task: 20%
Due: 11:55pm Sunday 2nd September, 2018 (week 7) Minimum time expectation: 20 hours
Learning Outcomes Assessed
The following course learning outcomes are assessed by completing this assessment:
- Understand the significance of detailed project planning and control, good communication and documentation and the use of appropriate tools in order to provide a quality product
- Understand the distinction between software engineering and programming, and thus the distinction between a software configuration and a program
- Understand the methods and techniques involved in designing, implementing and maintaining an information system, in particular using an object-oriented approach
- Demonstrate skills in designing and implementing an information system.
A new party plan company (which sells any product of your choice) is opening in Australia. This company operates on a membership structure, offering discounts on the recommended retail price of product purchases based on a tiered membership approach:
|Membership Level||Discount on Product Purchases|
You have agreed to design and develop a small Java console program for this company, with four menu options.
Option 1: Create a member. The member needs to have a name and a membership tier.
Option 2: Make a purchase. Select a member who is making a purchase, enter the total recommended retail value of that purchase and calculate the corresponding discounted price.
Option 3: Display a summary of transaction data for the current session, showing:
- The total number of sales processed and the payment amount received for these sales
- The total number of sales processed for each membership tier, the payment amount received for each tier and the total discount given at each membership tier.
Option 4: Exit the system
After completing any of the first three options, the program returns to the menu so the user can select another option. After selecting the fourth option, the program closes. There is no need for the program data to persist once the program has closed.
The party plan company wants to be able to add additional membership tiers at a later date, so the system needs to be flexible. This means you will need to use an interface for processing payments, and polymorphism for the various membership classes, so that new, different levels of membership may be added at a later date with minimal updates to the code. The company has also asked that you provide them with some documentation before you
commence coding, so that they are able to verify that the program you intend to code will address their requirements. They would like to see use cases to summarize the requirements in written format, as well as use case diagrams, class diagrams and sequence diagrams.
You are required to submit the assignment before the due date consisting of:
- A Zip file containing the following (submitted via Moodle under the Assignment 1 link) o A written report comprising:
- Use Cases summarizing the requirements
- UML Diagrams, created in Enterprise Architect, comprising:
- a Use Case Diagram for processing a hire agreement
- a Class Diagram of the intended system
- a Sequence Diagram for processing a hire agreement for a member.
- A short reflection (approximately 200-300 words) discussing the importance of requirements design and analysis, UML diagrams and object-oriented programming with interfaces and polymorphism. As an example, if you found that you changed your initial UML diagrams after you had commenced coding, you should explain what these changes were and explain what you learnt that led to these changes.
o Enterprise Architect file(s) containing your UML Diagrams for the Use Case, Class and Sequence Diagrams o Your finished Java program, addressing the requirements outlined in the Assignment Details.
