Take for example my domain as poco.
Domain driven design entity framework example. The application is available as of december 2010 as net port. Watched a tutorial by pluralsight in which they mention repositories and noticed that a repo normally contains basic crud operations create update fetch remove entity. I suspect each of the approaches has its merits but i m completely lost now and don t have the slightest idea of how to reconcile ef with ddd.
An orm is just here to bridge the gap between the relational data model residing in your database and an object model any object model. Nothing much was explained with regard to entity framework. It turns out that the ef creators wanted to.
An entity as defined by ef concretely means any object that you wish to map some subpart of your relational model to and from. Here are some thoughts on distinctions between aggregates and entities in domain driven design ddd in response to some good questions harry brumleve asked me via email. The team hopes that beyond concretely demonstrating ddd in a conventional system the example can become a platform for experimentation with new technology and innovative approaches.
In domain driven design entities and value objects can exist independently. In domain driven design it s common to keep business logic in a rich model. This happens when the logic we re trying figure out where to put doesn t involve one entity in particular there are cases where it s ok like our job example utilizing the question entity but there are other cases where the two entities involved shouldn t necessarily know about each.
Sometimes it doesn t feel natural and doesn t make sense to put certain domain logic inside of an entity. I am building an application using domain driven design that is using entity framework. Here is the relevant content from the email.
This article is about how to apply a domain driven design ddd approach to the classes that the entity framework core ef core library maps to a database. My goal is to allow my domain models that get persisted with ef contain some logic within them. Then i did a podcast with bryan hogan where we discussed domain driven design ddd and he goes further than my crud only create read update and delete approach he says that the entity classes.
