Scenаriо: Heаlthcаre Appоintment Management System Yоu are tasked with designing a Healthcare Appointment Management System. This system will allow patients to: Search for available doctors and book appointments. Receive reminders for upcoming appointments. Make online payments for consultation fees. Track the appointment history. Notify doctors about patient arrivals and cancellations. Tasks: 1. Component-Based Architecture Using Component-Based Architecture (CBA) principles: Identify five components for the system (e.g., Doctor Availability Manager, Payment Handler). For each component: Define its responsibility. Describe one interface method it would expose (e.g., getAvailableDoctors(specialty, date) for the Doctor Availability Manager). Identify one dependency with another component. 2. Service-Oriented Architecture (SOA) and Middleware Design the system using Service-Oriented Architecture principles. Include the following services in your architecture: Appointment Booking Service. Payment Processing Service. Notification Service. Draw a diagram showing: Services and their interactions. Use of middleware to handle communication. Indicate whether interactions are synchronous or asynchronous. 3. Design Patterns and Event-Driven Architecture Explain how the Publish-Subscribe Pattern and Event-Driven Architecture can be applied to this system. Use the following events as examples: Appointment creation or cancellation. Payment confirmation. Reminder notifications for upcoming appointments. Draw a diagram showing the Publisher, Subscribers, and the flow of events. 4. Reflection on Architectural Patterns Answer the following questions: Compare the Hierarchical Architecture and Layered Architecture. Which one would you recommend for managing patient records and why? Discuss how using virtual machines or containers could improve system scalability and security. Describe one challenge in managing dependencies and ensuring interface compatibility in CBA when integrating multiple services. Grading Rubric: Component-Based Architecture (10 points): Clarity of identified components, responsibilities, interfaces, and dependencies. SOA and Middleware Diagram (15 points): Completeness, correctness, and clarity of services, middleware usage, and communication types. Event-Driven Architecture and Publish-Subscribe (10 points): Explanation of the pattern and accuracy of the event flow diagram. Reflection (15 points): Depth of comparison, feasibility of recommendations, and understanding of challenges.
