More Business Object Abstraction Fun: Abstracting basic CRUD operation

In my previous post I spoke about how we had gone about abstracting the injection of Repositories into our business objects in the project I am currently working on. What we went on to find was that once we had abstracted the repository, and the responsibility of injecting the repository into an EntityBase class, we were then able to identify more behavior that was common among our objects that we were able to abstract.
