Ted Neward on OR/M
Ten
Neward has posted a long post about OR/M - The
Vietnam of Computer Science. The first part of this post is a Vietnam war history
lesson, and I kind of missed the point, then he goes on to point at various
issues with OR/M.
I
don't quite get the point of the post, to tell the truth, and I am tempted to raise Godwin's Law in this
matter
He
raises some valid points, but each of those issues are already mostly solved
issues.
To
give some examples:
- Entity identity vs. Row Identity –
Identity maps and Unit Of Work handle this issue.
- Concurrency - Last Write Win, Optimistic Concurrency,
Explicit locking.
- Caching across a web farm – Use a distribute
cache.
