Models

As you know an MVC model is concerned with data

Models are .cs files that live in the MVC Models Folder

There are four models we need

• Photo the base model that is the same as the SQL table
• PhotoCreateViewModel used by the create form
• PhotoEditViewModel used by the edit form
• PhotoListViewModel used by the gallery display interface (for paging)
