Question

The objective of this assignment is to apply and consolidate skills acquired in the analysis, architecture, and design disciplines through analysis of a simple case study, and to express the results through the relevant UML diagrams. Part A ? Non Functional Requirements (20 marks);1. Analyse the Case Study documents and determine the non-functional requirements (NFRs) or system quality attributes necessary to meet the needs identified in the Case Study. Document your analysis with a System Wide Requirement document. Make sure your document addresses;a) Required system functionality not captured by a single use case (eg auditing, printing, authentication).;b) The FURPS+ categories of system attributes.;c) Any required system interfaces with external systems.;d) Any business rules that must be applied.;e) Any constraints that will affect the design of the system.;Use the System Wide Requirement Specification template provided in the Resources/Assignment 2 section of the subject Interact site. (20 marks) Part B ? System Architecture (40 marks);2. Analyse the Case Study documents and develop a candidate architecture to meet the functional and non-functional requirements you have identified in Assignment 1 and Part A of Assignment 2. Document this candidate architecture with;i. An Architectural Notebook. Make sure this notebook addresses;a) The key concerns driving the overall architecture.;b) Assumptions and dependencies;c) Architecturally significant requirements;d) Decisions, constraints, and justifications that shape the architecture;e) Architectural mechanisms to be applied;f) Key abstractions;g) Any architectural frameworks or patterns that will be applied;Use the Architectural Notebook template provided in the Resources/Assignment 2 section of the subject Interact site. (20 marks);ii. A high level Logical View of the architecture in the form of a UML component diagram. (10 marks);iii. A Physical View of the architecture showing how components will be deployed on hardware in the form of a UML Deployment Diagram. (10 marks) Part C ? Detailed Design (30 marks);3. Show how your architecture will support the critical core use case for the system by developing a detailed design to support that use case. Your design should be consistent with your architecture and respect any component and hardware boundaries. Document your design with;i. A UML Communication Diagram showing the interaction between user interface, control, and domain object classes for the critical core use case. (10 marks);ii. A UML Sequence Diagram showing the interaction between user interface, control, and domain object classes for the critical core use case. (10 marks);iii. A UML Design Class Diagram showing all classes, attributes, methods, and relationships required to support the critical core use case. (10 marks) Part D ? Reflection on Object Oriented Design (10 marks);4. Reflect on the design principles you have employed in your architecture and design in a written text of between 200 to 1000 words (between 1 and 5 pages). Make sure your reflection addresses;a) A discussion of any issues you encountered in deciding on a particular architectural framework or pattern.;b) Identifies and discusses any object oriented design principles you applied in your detailed design.;c) Identifies and discusses any software design patterns you applied in your detailed design.;Rationale;This assignment elicits performance of taught skills in the requirement and analysis areas relevant to the following learning objectives;be able to analyse and validate system requirements;be able to produce and validate analysis and design models for a system;be able to evaluate a problem and determine the appropriate architectural style for the solutio;be able to evaluate and choose appropriate software design patterns to compose the design of a software system;be able to demonstrate use of a CASE tool to document the models in a system;Marking criteria System Wide Requirements;?
