COIT20258 Software Engineering

The purpose of this assessment item is to assess your skills attributable to the following learning outcomes and achieving the expected graduate attributes of advanced level knowledge, and cognitive, technical, and creative skills, and professional level communication.

Develop models of the proposed multi-tiered software application as per the requirements identified following formal requirements engineering procedures

Assessment task
Your task in this assessment is to analyse the given case study, apply the principles of requirement engineering by eliciting functional and non-functional requirements, and documenting system and user requirements specification. You will also choose appropriate modeling techniques to model the system and design the system architecture.
Problem
People residing in owner occupied or rented houses maintain their households which is an essential process requiring continuous collection, storage, and use of information originating from many external sources. Household maintenance includes organising utility services, recording equipment purchase details, organising insurance, monitoring and control heating, ventilation, and air-conditioning (HVAC), undertaking cleaning and repairs of household appliances and vehicles.
An eHome provides a conceptual model incorporating a Family System and subsystems for home and personal life management where necessary information can be stored, accessed, and some level of automation can be achieved for carrying out many tasks. There are many External Entities with which Family System interacts such as schools for children’s education, medical professionals for health-related activities. One of the identified subsystems within the Family system is Housing and Transport. There are few external entities identified as part of this subsystem and these include:

Product suppliers
Government agencies
Service providers
Energy supplier
Water supplier

You are asked to develop the Housing and Transport System (HTS) which will be integrated into eHome with other subsystems. The initial task is to complete the requirements
ngineering process by eliciting functional, non-functional, system and user requirements. You should also develop models of system architecture, context model, use cases, and behavioural models such as sequence diagrams.
The users are the ’Home Users’ who are public residing in suburban homes who will not have insight into organising information, or automating tasks. Therefore, Home Users cannot provide guidance in the design or functionalities of the HTS.
An example of information originating from a product supplier can be the details of a refrigerator purchase. This includes the brand, model number, warranty, price, purchase date, seller details. Using this example, the Home User should be able to input purchase details for any equipment/appliance purchase using an easy-to-use interface. The other features that would help the Home User could be reminders on expiry date of warranty or any periodic service. Home User should be able to display a list of appliances in a report format.
You should develop:

Context Model

Show the information flow between External Entities and HTS

System architecture

Use Model -View-Controller

System requirements including functional and non-functional requirements

Use cases to depict the functionality of the system

You can use your own experience or literature review or external input to understand inputs and any automation needs

Sequence Diagrams for a product details entry and a product specific information search and display

Use case diagrams

UML class diagram Identify the classes required

GUI design

This should be consistent with the Use cases and use case diagram. You can use SceneBuilder to create GUI.
