Model or ViewModel?

Question

WPF

Please tell me if the class is not used as a DataContext in any view, but in the ViewModel there is a collection of objects of this class that is attached to the view (for example, to the DataGrid), then this class is a Model or a ViewModel? Personally, it seems to me that all the same ViewModel, because all the same, its properties are involved in binding, but I'm not sure ... And what is important, this class also has other public properties and methods that are not bound, but simply used in the code.

Answer 1

The data access layer is the model.

Answer 2

Simply put, you have a VM, the VM has properties, these properties return some kind of data, data is a model.
VM is also a model, but its tasks are different, receiving, transferring data to the DataLayer, setting element properties, etc. VM is an intermediary between model and view.
