  • 0

I just cannot seem to get my head around what exactly is the MODEL in MVP.

If I have a layered architecture PRESENTATION / APPLICATION / DOMAIN / INFRASTRUCTURE, what exactly is the MODEL?

  1. DOMAIN objects accessed through
    lower layers?
  2. A separate object defined in the
    PRESENTATION layer that maps to the
    UI and uses data obtained from a
    lower layer?

If someone could clear my understanding on what is the MODEL it would be greatly appreciated.

    The Model is normally the group of classes/types/components that represent the core domain (business or otherwise) that your application operates within. These are the classes that perform the key logic required, often in the form of business rules, and also consume/manipulate data.

    In your layered example, the Model would mostly be found in the Domain layer but could also be in the Application layer.

    I think you’re having difficulty understanding it because you are trying to combine two separate architectural patterns, or ways of looking at the application, being n-tier/n-layer versus MVP.

    It’s completely reasonable (and quite common) to use some sort of Model/View approach while at the same time applying layering in your application.

    Maybe you should focus on them one at a time to start with and then overlay them when you are more familiar with both.
