Class based modeling
The document discusses class identification for a system. It identifies potential classes like homeowner, sensor, control panel, system, and sensor event by examining nouns in use cases. It then evaluates the potential classes against characteristics like retained information, needed services, and common attributes to determine which should be defined as classes in a requirements model. The security system, sensor, control panel, and sensor event classes are selected as they meet the evaluated characteristics.
