Entity Framework: Data Centric vs. Object Centric
- by Eric J.
I'm having a look at Entity Framework and everything I'm reading takes a data centric approach to explaining EF. By that I mean that the fundamental relationships of the system are first defined in the database and objects are generated that reflect those relationships.
Examples
Quickstart (Entity Framework)
Using Entity Framework entities as business objects?
The EF documentation implies that it's not necessary to start from the database layer, e.g.
Developers can work with a consistent
application object model that can be
mapped to various storage schemas
When designing a new system (simplified version), I tend to first create a class model, then generate business objects from the model, code business layer stuff that can't be generated, and then worry about persistence (or rather work with a DBA and let him worry about the most efficient persistence strategy). That object centric approach is well supported by ORM technologies such as (n)Hibernate.
Is there a reasonable path to an object centric approach with EF? Will I be swimming upstream going that route? Any good starting points?
