Something like this: SchoolsViewModel +- SchoolViewModel +- LessonViewModel +- PupilsViewModel +- PupilViewModel +- TeacherViewModel +- PupilsViewModel +- PupilViewModel +- LessonsViewModel +- TeachersViewModel And so on... In addition, a single view model can appear in more than one place, depending on whether the user is browsing by lesson or pupil, etc. How would you allow for sharing of child ViewModels

Half way in my development process, I started to see myself leaving lots of business logic inside of Table classes. I've heard sayings that it's not a good idea to pollute the model
