Task
In this assignment, you are required to complete the followings to validate your system designs.
You have the following two choices to develop detailed object-oriented design models. You also need to submit a proper documentation describing the different aspect of developed component, within 2000 words.
Task 1: The students who have expertise in object-oriented programming are required to validate their system design through developing a prototype for at least one subsystem of chosen case study. You have an option to use any object-oriented programming language such as C++, Java, C#, etc. to develop this subsystem.
OR
Task 2: The students who have no expertise in object-oriented programming are required to validate their system design using interaction diagrams (i.e., communication diagrams or sequence diagrams) for at least one subsystem of chosen case study. To do this, identify 3 (three) most important use cases for the subsystem and develop communication diagrams or sequence diagrams for these use cases.

Rationale
The purpose of this assessment task is to develop student's skills and knowledge in :
• validating an OO design through the construction of a prototype
• converting design diagrams into program code
• preparing project documentation
• developing presentations, and through peer review to reflect on their own practice and improve their design.

Criteria HD DI CR PS FL
Task 1 (70%): The students who have expertise in object-oriented programming are required to validate their system design through developing a prototype for at least one subsystem of chosen case study. You have an option to use any object-oriented programming language such as C++, Java, C#, etc. to develop this subsystem.
OR
Task 2 (70%): The students who have no expertise in object-oriented programming are required to validate their system design using interaction diagrams (i.e., communication diagrams or sequence diagrams) for at least one subsystem of chosen case study. To do this, identify all possible use cases for the subsystem and develop communication diagrams or sequence diagrams for these use cases.

Task 1:
Fully functional prototype using major principles of object-oriented programming such as encapsulation, data abstraction, polymorphism and inheritance. Each variable, function/method, loops, if/else statements, etc are well commented.

OR
Task 2:
All possible use cases of the subsystem are identified; developed communication or sequence diagrams are correctly showing logical flow of the system activities, input/output messages, and accurate symbols/notations.
Task 1:
Mostly fully functional prototype using major principles of object-oriented programming such as encapsulation, data abstraction, polymorphism and inheritance. Each variable, function/method, loops, if/else statements, etc are well commented.

OR
Task 2:
Major use cases of the subsystem are identified; developed communication or sequence diagrams are correctly showing logical flow of the system activities, input/output messages, and accurate symbols/notations.
Task 1:
Mostly fully functional prototype using major principles of object-oriented programming such as encapsulation, data abstraction, polymorphism and inheritance. Each variable, function/method, loops, if/else statements, etc are well commented.
Minor omission only

OR
Task 2:
Major use cases of the subsystem are identified; developed communication or sequence diagrams are correctly showing logical flow of the system activities, input/output messages, and accurate symbols/notations.
Minor omission only

Task 1:
Prototype not always functional using major principles of object-oriented programming such as encapsulation, data abstraction, polymorphism and inheritance. Each variable, function/method, loops, if/else statements, etc are not well commented.

OR
Task 2:
Some use cases of the subsystem are identified; developed communication or sequence diagrams are mostly correct showing logical flow of the system activities, input/output messages, and accurate symbols/notations.
Task 1:
Prototype has major errors and not working.

OR
Task 2:
Few use cases of the subsystem are identified; developed communication or sequence diagrams are wrong.
Task 1 & Task 2 (30%)
Submit a proper documentation describing the different aspect of developed component, within 2000 words.
Task 1 & Task 2:
Comprehensive documentation which describes each component of developed system and has insights and awareness of deeper more subtle aspects of the case study.
Task 1 & Task 2:
Mostly comprehensive documentation which describes each component of developed system and has insights and awareness of deeper more subtle aspects of the case study.
Task 1 & Task 2:
Mostly comprehensive documentation which describes each component of developed system and has insights and awareness of deeper more subtle aspects of the case study.
Minor emission only
Task 1 & Task 2:
Reasonable documentation describes few components of developed system.
Task 1 & Task 2:
Documentation is wrong and not matching with system components.
