Thanks Paul.

It can even be incorporated into the build process so you don't have to think about doing it. I've also seen other products that just require you to update their model of the data when you change the underlying SQL model. It rebuilds whatever it thinks needs rebuilding (in some cases code, other cases it's just meta data).

>For my stuff I made a decision to use a methodology where the entities can be rebuilt as the structure changes but I am not using any kind of mapper. I'm perfectly happy using SQL and stored procs, and I wasn't thrilled with most of the syntax that forces an object model on top of SQL. That said, I can see the appeal and I kept looking at various ORM products (NHibernate, LLBLGen, etc.).
