A state-level vehicle registration system where owners register vehicles, maintain current insurance policies, and state police can verify registration and insurance compliance during traffic stops.
O que há neste desenho
Entenda as decisões por trás dele.
01
One owner can own multiple vehicles, so a one-to-many relationship links Owner to Vehicle.
02
Each vehicle can have multiple historical registrations and insurance policies over time, modeled as one-to-many relationships.
03
StatePoliceCheck references Registration to record law-enforcement verification events without duplicating owner or vehicle data.
Use when designing a database for motor vehicle registration, insurance compliance tracking, or law-enforcement lookup systems.
