We plan to construct a database for gathering sensing data from vehicles.

$$ Each vehicle has VIN, license$\_$plate, and color. Each vehicle may have a model.

$$ A model has id and name.

$$ Each vehicle creates sensor dataset.

$$ Each sensor data includs time, GPS$,$ rpm$,$ and acceleratoin. We assume that a

sensor acquires data at one$-$second intervals.

$$ A customer has id and name.

$$ A customer can own multiple vehicles and a vehicle can be owned by multiple

customers.

Draw an ER diagram for this application. Specify key attributes of each entity type and structural constraints on each relationship type. Note any unspecified requirements, and make appropriate assumptions to make the specification complete.
