A charter company owns boats that are used to chart trips to islands. The company has created a database to track the boats it owns, including each boat’s ID number, name, last maintained date, seating capacity, purchased year, and cost per hour used. The database also keeps information about each island, such as its unique ID, name, population, ticket price per person, and overall tour hour per trip. The database also maintains information about each captain it employs and assigns to trips, such as captain ID, Social Security number, first name, last name, address (including street, city, and state), zipcode, phone number, and date of birth. In addition, all information about each trip, including trip ID, the date that the trip takes place, and the number of people on the trip, is also kept in the database.
THIS IS THE PART I NEED HELP INDENTIFYING THE RELATIONSHIP Each trip takes only one boat, but a boat may be used for multiple trips on different dates or may have not been used for any trip yet. A particular trip travels to only one island, but an island may be visited by different trips or may have not been visited by any trips. Each particular trip has only one captain assigned to it, but a captain may be assigned to different trips on different dates or may have not been assigned to any trip.I only need help with determining the relationship which is the last paragraph. Is it 1:1, 1:M, or M:N
