LancRides is a car rental company which has been founded
recently in Lancaster. It currently has four branches opened in
Lancaster, Morecambe, Garstang, and Carnforth. LancRides is
planning to expand to Preston in the future. A branch has an
address and a telephone number. Each rental car must be associated
with exactly one LancRides branch. A rental car can be identified
by its registration number and has the information about the model
and the production year. Each employee working at LancRides has a
unique tax file number (TFN), a name and an address. LancRides
employees consist of managers, mechanics, and customer service
representatives. Every employee must work at exactly one branch. A
customer of LancRides should provide driver license number, name,
and a contact number. A customer can rent a car from a LancRides
branch and details about the rental such as the rental period and
price should be recorded. If a customer is not satisfied with the
rental service provided, this customer may submit a complaint to a
customer service representative who is identified by a unique
service representative ID and thus a distinct reference number and
detailed description of the complaint should be recorded. The
manager, associated with a manager ID, of a branch will handle all
the complaints with respect to this branch and has an urgent
contact number in case of emergency. Mechanics working at a branch
inspect the cars associated with the branch and record the
condition and inspection date. A car must be inspected at least two
times per year. Each mechanic has a certificate ID and a skill
level, and might have another mechanic as the supervisor. The
supervisor must have a higher skill level compared to the mechanics
supervised by this supervisor.
