This project is based on the information design model shown below.
The corresponding app from the previous assignments is to be extended by
adding the possibility to manage data about international organizations, with countries as
members, and about cities, as capitals and headquarter
locations. This is achieved by adding corresponding model
classes InternationalOrganization and City, and
the following unidirectional associations:
a many-to-many association between
InternationalOrganizationandCountryassigning zero or more countries as the members of an international organization, and, inversely, zero or more international organizations to a country,a one-to-many association between
CountryandCityassigning zero or many cities to a country and, inversely, exactly one country to a city.
