Read the below case study and answer ALL questions. Design and Implementation of a Scalable, Secure, and User-Friendly Online Learning Management System (LMS) for a university: A Case Study Your team is tasked with designing and implementing an Online Learning Management System (LMS) for a university. The system will allow students to enrol in courses, access course materials, submit assignments, and participate in discussions. Instructors will be able to create courses, upload materials, grade assignments, and manage student enrolments. The system must be scalable, secure, and user friendly, catering to both on-campus and remote students. QUESTION 1 The application of Software Engineering principles to the development of a reliable, maintainable, and adaptable, and Online Learning Management System (LMS) is crucial. With reference to the case study scenario answer the following questions. 1.1 Identify the core attributes of good software that should be prioritized in the development of the LMS. 1.2 How does the complexity of software affect the planning and building of the LMS, especially when the system needs to meet different user needs and keep up with new technology? 13 How can software engineering principles be used to make sure the LMS can easily adapt to fast changing technology, such as software and hardware? 1.4 Identify 2 (two) challenges that might arise when creating a custom LMS for the university if the requirements change during the project. 1.5 State 2 (two) reasons why web technologies like Cloud computing and Software as a Service (SaaS) are important when in building the LMS. QUESTION 2 Using software development processes and approaches is essential for successfully creating ANY software like LMS. Refer to the case study scenario and answer the following questions. 2.1 What are the 4 (four) basic steps in the software development process? Explain how each step would be used to develop the LMS. 2.2 Name 4 (four) approaches that you could use to ensure sure that ALL the LMS requirements are correctly gathered? 2.3 Identify explain 1 (one) risk that could arise at each stage of developing the LMS and suggest 1 (one) way to reduce or manage the risk. 2.4 is using an incremental development approach a good fit for the LMS project and justify your answer? State one possible 1 (one) pro and con of this approach for the LMS development? QUESTION 3 Development of the LMS using Agile software development. Answer the following questions. 3.1 Explain what is Agile software development is, and state 1 (one) reason why it is particularly suited for the development of an LMS in a rapidly changing educational environment? 3.2 Mention 4 (four) key characteristics of Agile development and explain how these characteristics would be applied to ensure the successful and flexible development of the LMS? 3.3 What are the 4 (four) main values outlined in the Agile Manifesto and discuss how these values would influence the development of the LMS, especially in responding to changing user requirements. QUESTION 4 Requirements Gathering and Validation for the Development of the (LMS). Answer the following questions. 4.1 Mention ANY 2 (two) key user requirements for students and instructors in the LMS, and explain how would these requirements guide the system's design? 4.2 How would you differentiate between functional and non-functional requirements when gathering specifications for the LMS? 4.3 During the feasibility study phase, list ANY 2 (two) operational, technical, and economic factors would you assess for the LMS project. 4.4 State ANY 2 (two) potential challenges that might arise during the requirements elicitation and analysis phase for the LMS, and how would you address them? 4.5 State ANY 4 (four) techniques that you could use to validate that the LMS requirements accurately reflect the needs of the university. QUESTION 5 System Modelling and Design for the Development of an Online Learning Management System (LMS). Answer the following questions. 5.1 What type of system model would you use to illustrate the interaction between students and the LMS, and why is this model important for understanding user requirements? 5.2 Describe how a structural model, such as a class diagram, would be useful in designing the LMS. particularly in managing the relationships between courses, students, and instructors. 5.3 Given that the LMS needs to support both on-campus and remote students, which system model would best help in visualizing the system's context and external interactions, and what key elements should this model indude? 5.4 How could behavioural models, such as state diagrams, be used to model the LMS's response to different events, such as a student submitting an assignment or an instructor grading it? QUESTION 6 Design and Development Considerations for a Scalable and Secure (LMS). Answer the following questions 6.1 How would you apply object-oriented design principles to identify and structure the key components of the LMS, such as courses, students, and instructors? (4 Marks) (20 Marks) (4 Marks) (4 Marks) (4 Marks) (4 Marks) (4 Marks) (20 Marks) (5 Marks) (5 Marks) (5 Marks) (5 Marks) (20 Marks) (5 Marks) (5 Marks) 6.2 What architectural design considerations would you need to consider ensuring that the LMS is scalable, secure, and supports both on-campus and remote students? 6.3 Discuss how you would manage configuration and version control during the development of the LMS, especially when handling multiple features and updates simultaneously. 6.4 Discuss the advantages and potential risks of using open-source software in the development of the LMS. How would you mitigate these risks while benefiting from the advantages? QUESTION 7 System Design and Security Considerations for a Scalable Online Learning Management System LMS 7.1 How would you apply client-server architecture to ensure that the LMS can support many simultaneous users, both on-campus and remote? 7.2 What security measures would you implement in the LMS to protect sensitive data such as student grades, assignment submissions, and course materials? 7.3 Considering the need for a user-friendly interface, how would you design the LMS to cater to the different needs of students and instructors? 7.4 How would you implement and manage the scalability of the LMS to accommodate future growth, such as an increase in the number of students, courses, or additional functionalities?
