You are designing an Android application for an agency that manages

ship ports. You are responsible for building the app functionality where

managers should be able to log in and view the different ports, and for

each port they should be able to generate a list of all passengers

traveling in a passenger ship $($handling freight ships is a feature to be

added later$).$ The application must follow the MVC design pattern, and

you may create any classes needed. Draw a UML diagram to outline this

application. The outline must contain the classes needed in the app

$($names$,$ attributes, and methods$)$ as well as the relationships between

these classes. Do not write any code.

Note that, as in any program design, there may be multiple choices for

relationships between some classes. In such a case, select only the most

relevant.
