P1 a3 bike share relationships

A city bike-share scheme is designing a database. These facts are true of the scheme.

• Every rider has exactly one membership card, and every card belongs to exactly one rider.
• A station has many docks, and each dock is at exactly one station.
• Over a year, a rider rides many different bikes, and each bike is ridden by many different riders.
