I am trying to build a WPF application using the MVVM pattern. It would be my first one.

In my database I have 2 tables a reports table and a columns table. Basically I just want to store the skeleton of reports by storing the name and some minor infos (header row…) and save all columns in the other table.

I am wondering what would be the best approach when creating my model:

  • should I do 2 models (Report and Column) for each table? And make an observable collection of Columns
  • Only 1 model and create a POCO Column with a regular list of Columns

If I go with the 2 models approach should I implement 2 modelViews or can I group everything in one modelview as I will work with only one report in the view (like the edit report view)?

Hope I was able to clearly explain my situation.

    Just do each separately (i.e. one View/ViewModel/Model per table). You can refactor common items later (and/or as you’re building).
