My ORM is generating objects reflecting the database table structure. This objects are extensible, so I’m able to add new properties and methods. This objects do not contains any persistence logic,so I guess they are persistant ignorant.
Should I use this object as my domain objects or should I create new objects for main domains model ?
As a pro for creating new object I would consider that when a database table changes it won’t break the application.
As a con for creating new object I would consider the additional mapping and more complexity in the app.
My answer is, it depends. If you have a lot of complex logic assosiated with many entities you should create another layer of domain, but for the objects that got no logic and just serves you as a db port, don’t bother to create a separate object cause its meaningless.
To sum up, if a db change will cause domain change, don’t separate if it won’t, separate.
