Since Fog Creek Software's in-house language, Wasabi, has compile-time code generators built in, we use them to automatically create the meat of our entity classes that map to database tables. So instead of writing a class with a dozen different properties and methods, we can just write:
_
Class CKiwi
End Class
and CKiwi will have Load(ix As Int32), Commit(), and fields/properties for every column defined in its underlying schema for the Kiwi table. It keeps us from having to have huge O/R M libraries, but still allows us to quickly add a table to our products.
