> and breaks terribly when you step out of it Maybe you mean something else, but I haven't had any issues when I've had to break out of the ORM and write portions in SQL. (usually once or twice every couple of development man years) I'm not sure what type integration is, but the ORM I'm most familiar with does allow spanning multiple DBMS's with the same code. (unless when you had to break into DBMS specific SQL for performance reasons) Is type integration allowing static type checks against your query language? Entity Framework does this as well. I think EF is the second type of ORM, unless I'm misunderstanding you.
