2. The State of New York certifies firefighters throughout

the state and must keep track of all of them,

as well as of the state’s fire departments. Each

fire department has a unique department number, a

name that also identifies its locale (city, county, etc.),

the year it was established, and its main telephone

number. Each certified firefighter has a unique firefighter

number, a name, year of certification, home

telephone number, and a rank (firefighter, fire lieutenant,

fire captain, etc.) The state wants to record the

fire department for which each firefighter currently

works and each firefighter’s supervisor. Supervisors

are always higher-ranking certified firefighters.
