Relationships in Databases for Smart City Applications
In smart city application databases, entities are interconnected through relationships that define the flow and associations of urban data. Key relationships include:
Urban System-Sensor Relationship
- One-to-many relationship
- Each urban system can have multiple sensors, and each sensor is associated with one urban system.
Sensor-Event Relationship
- One-to-many relationship
- Each sensor can generate multiple events, and each event is associated with one sensor.
Service-Event Relationship
- Many-to-many relationship
- Each service can be associated with multiple events, and each event can be associated with multiple services.
How to Design a Database for Smart City Applications
Smart city applications leverage technology to improve urban living, enhance sustainability, and optimize resource management. These applications rely on efficient data storage, management, and analysis to handle diverse datasets from various urban systems and sensors.
Behind the functionality of smart city applications lies a well-designed database architecture capable of integrating, processing, and visualizing complex urban data. In this article, we will explore the essential principles of designing databases tailored specifically for smart city applications.
