+  * a `Person` object stores `StudentId`, `Name`, `Address`, `Phone`, `Email`, `Role`, `Course` objects.
   * contains an ArrayList of `Module` objects which is optional.
 * stores the currently 'selected' `Person` objects (e.g., results of a search query) as a separate _filtered_ list which is exposed to outsiders as an unmodifiable `ObservableList<Person>` that can be 'observed' e.g. the UI can be bound to this list so that the UI automatically updates when the data in the list change.
 * stores a `UserPref` object that represents the user’s preferences. This is exposed to the outside as a `ReadOnlyUserPref` objects.
 * is intentionally designed to be independent of other components (e.g., UI, Logic, Storage) to maintain a clean separation of concerns. This ensures that the Model layer is solely responsible for managing data and that data structures make sense on their own. This independence enables easier maintenance, testing, and adaptability of the data structures, as changes in one component (e.g., UI) do not affect the Model.
