1) A database is to be constructed in order to keep the records of all
ferry companies, boats, and trips (of
short/medium/long distance) operated in a water region. Each
company has a number of boats. Each boat
has a unique plate/ID number, model, and other information (like
number of seats and so on). For each trip, it is
desirable for insurance purpose to keep track of the ferry company
and actual boat involved in each trip, and
the departure and arrival ports, date, time, etc. Design an ER
schema diagram for this application, stating any
assumptions you'd like to make.
