Assessment item 1— Assignment 1
Due date: Friday of Week 6 (24th April 2020) 11.45 pm AEST
The purpose of this assessment item is to assess your skills attributable to the following
|Apply software design and development principles
Complete appropriate documentation for requirements, system modelling and design, software
implementation, testing and evolution
Illustrate a detailed design for a layered information system using appropriate design methods
2. Assessment Task
Your task in this assessment is to analyse the given case study, understand the user
requirements, and develop the necessary design and documentation for a
Traffic Accident Reporting System (TARS) for Queensland Road and Transport Authority
your client. You have to complete the requirements engineering and design of the system,
keeping in view that in the next phase as part of your second Assessment you will
be completing the implementation, and testing of the TARS System.
3. Case Study
Queensland Road and Transport Authority (QRTA), as part of Queensland Government
currently offers the road and transport services to the road users. This service
is dedicated to collecting, storing, manipulating, and making available Road
Accident Information important to the delivery of services to Queensland road users.
Each motor vehicle will have a unique identifier (plate number) assigned by the
system when registered for the first time. The QRTA wanted a flexible system with room
for change in the future and prefer a layered design and implementation with the data
stored in a database. The system is used by the QRTA staff to Create, Edit, Browse,
Search on past road accidents in QLD. A View option should also be available to list all
the accidents based on the “vehicle plate number” for reporting purposes. The system
should also have the ability to update/change the vehicle owner information such as
address or the phone number.
Response to user actions must be reflected in the interface. The system
should be developed as a Java desktop application which runs on a
windows operating system with a graphical user interface. The Java application
should be developed in a single tier using MVP (model view presenter)
pattern. QRTA expects the system to be developed in two parts (Design and
The user updates the Vehicle information by interacting with the system. A Vehicle
record consists of [id(plate number), model, year, owner name, owner address,
owner phone number]. A sample record in database exists as (“124-QAY”,
“TOYOTA”, 2018, ”Tom Jones”,”somewhere in Townsville”, ”0467567356”). An accident
record in database exist as [id(auto-generated), location, comments, vehicle id]. A
sample record in database exists as (1, “intersection of Flinders and Ingham
roads Townsville”, “hitting an other car from behind”, “124-QAY”), remember! an
accident may involve multiple vehicles. Initial database script files will be provided.
Sufficient error handling must be implemented to prevent data entry errors during database
update and for the search option. The application when developed should automatically
attempt to connect to the database before the user interface screen is displayed and exit
with a message for a failed connection.
When an accident is reported to the front desk, the system user must be able to check if
the vehicle is already in the database and offer to update the information, if not then allow
the user to add a new recored as a new vehicle and then add a new accident. The system
must also allow user to add other vehicles to one accident.

4. ASSESSMENT COMPLETION GUIDELINES
You should submit a report containing the following sections as listed below.
1. System Requirements
Provide functional and non-functional system requirements.
2. System Architecture
Provide a package diagram for the MVP design showing all the classes involved.
3. Use Case Diagrams
Use UML to develop use case diagrams clearly showing the users (actors) and the main
functions of the system
4. UML Class Diagrams
Identify the classes based on the descriptions and the functions required. Show clearly
public, private access and associations between classes.
5. Sequence Diagrams
Provide two sequence diagrams with annotations for update and search operations.
Develop the sequence diagrams clearly showing the user interactions and the different
layers of the system.
6. Data Design
Provide database table design with column names and types
7. GUI design
Develop the GUI design based on the use cases and the sequence diagrams. You can be
creative and only an indicative GUI is required. Developers are free to use this design as
is or to do things differently.
Note: You can use the NetBeans Forms to develop a GUI design.
8. Requirements Matrix
Provide a table as below to maps requirement to action for each button and inputs required.
Table II: Requirement Matrix
9. Test Plan
Provide test use cases for update and search operations.

Use the ‘Assignment1Template.dot’ file available from the Unit website under the
Assessment folder for creating your report document file. Download the template and
save it in your directory. Locate the file in your directory using File explorer and double
click on it. This will create a document file named ‘document1’ by default. You can save it
assigning the name you prefer and continue writing the report.
You should submit only the word document using the Assignment 1 submission link
available from the Unit website.
