Question 1 - Software Architecture - 80 marksGiven a case study, analyse the non-functional requirements of the proposed system, and define an architecture for the system. Illustrate the static structure of your architecture with logical and deployment viewsPart 1 – Non-Functional Requirement (NFR) Analysis – 20 marksConduct an NFR analysis for the given case study using the provided checklist as a starting point. Add to the checklist as appropriate for the case study. Present the results in tabular form as follows:NFRQuestionBenefitsCostsResponseStrategyPrioritySecurityIs security a concern?What sort of different access levels might be necessary?Protects the system from unintentional breaches of privacy.etcMakes the system harder to use, more expensive to build. May have performance implications.Yes, security is a concern, we don’t want customers seeing other customers data, and we don’t want staff access other staffs records.Authentication and Authorisation2Once you have considered all NFRs, rank them in priority from the stakeholder’s perspective. Do not allocate the same priority to any NFRs – make an executive subjective decision and rank them.Produce a summary of your (at least) 5 most important NFRs. Explain and justify why these are the most important from the stakeholder’s point of view.Part 2 – Architecture Notebook – 40 marksPresent this in the form of a Software Architecture Notebook with the following headings:1. Goals and Philosophy - identify the key non-functional requirements (e.g. security, reliability, availability, maintainability, compatibility, etc.) that the system is attempting to satisfy.2. Assumptions, Constraints and Dependencies - identify existing or proposed technology environments that will support or constrain the system. Identify external systems and databases with which the system will interact. Note: assumptions, constraints, and dependencies are pre-existing facts: they are observations, rather than the result of a choice.3. Architecturally Significant Requirements - identify key functional/non-functional requirements that have important implications for the technical architecture of the system and say what the implications are for those requirements.4. Decisions and Justifications - Identify the decisions made in determining the technical architecture and user interface technology. Justify these against the key goals and philosophies driving the architecture.5. Architectural Mechanisms – Identify the key strategies that you will implement to achieve the NFRs critical to your application.6. Architectural Style and Technological Framework – state the overall architectural style that you have chosen as the basis for your application and explain why it meets the goals of the architecture. Then identify the technical platform with which you will implement your design and explain why that platform is a suitable choice.Part 3 – Architectural Views - 20 marksReview the functional requirements for the system and identify a set of functional components. Review the system-wide services required by the system and identify a set of technical components. Illustrate your analysis with a component diagram showing logical or conceptual functional and technical components.Analyse the hardware and network layout of your proposed system and produce a deployment diagram showing that layout. Identify execution environments in each of your hardware nodes. Then map the functional and technical components you previously identified into the various execution environments as deployable software components. You may need to divide the logical components identified previously into smaller deployable units representing both horizontal divisions (presentation, business logic, and data layers) and vertical divisions (e.g. customer view, staff view, management view etc).Question 2 - Database Design- 20 MarksGiven a set of domain objects for the case study, define a set of database tables in 3rd normal form to represent those objects. Identify and discuss any new entity objects that perhaps should be recognised in the domain model.RationaleThis assessment task will assess the following learning outcome/s:be able to analyse and verify system requirements.be able to produce and verify analysis and design models for a system.Provide a mechanism to assess whether students have the required assumed knowledge to successfully complete the subject.Marking criteria and standardsQuestion 1 Part 1: NFR Analysis - 20 marksCriteriaHigh DistinctionDistinctionCreditPassMark17-2015-1613-1410-12LO2 How well does the NFR analysis reflect the concerns of stakeholders and consider the runtime and non-runtime system qualities necessary to make the system fit-for-purpose?Insightful and thorough understanding of system quality requirements demonstrated through accurate and comprehensive consideration of almost all NFRs.All NFRs clearly stated in problem domain terms.
