• View (or ModelView) is the structure that the WebApi service sends to and receives from the client. For each entity, the developer must create at least one view.
• View (or ModelView) is a Data Transfer Objects (DTO)
• For a given entity, the View (or ModelView) is a subset of the properties of the given entity and a subset of the properties of the direct and indirect master entities (in terms of the master-detail relationship).
