## Architecture
### Focusing on VMs
Graduator is based on the MVVM (Model-View-ViewModel) architectural pattern. The below UML class diagram details
the structure of the models, viewmodels, and views for `UnitsManager`, `Unit`, and `Subject`. Notice how, as discussed in [this subpart](#change-notifications-are-not-implemented-per-se),
to circumvent [this issue](https://codefirst.iut.uca.fr/documentation/mchSamples_Apple/docusaurus/iOS_MVVM_guide/docs/viewModels/changeNotifications/problematic/),
we insert an entire hierarchy of VMs in certain views, so that they can update all those VMs when a detail gets edited.
It's dirty, and it's staying that way for the foreseeable future.
