Question.5676 - Scenario: Imagine you are part of a core team tasked with designing a software system for a smart city traffic management solution. The system needs to efficiently manage traffic flow, monitor real-time data from sensors, and provide emergency services with instant access to traffic patterns. Your team is responsible for creating reusable software components, minimizing dependencies between them, and designing system diagrams that clearly represent the system's structure. Questions: Identify a suitable design pattern that can be used to structure the system's traffic monitoring module. Explain how it ensures cohesion and minimizes coupling between different components with suitable examples. Use UML to create a use case diagram for an emergency response system with four key actors, describing their roles and interactions for real-time traffic data access during emergencies.
