Hey All
I'm curious about a couple things...
1) How large the database is for the application that everyone is using nhibernate for?

2) Did you start using nhibernate with a legacy schema or was the schema designed with nhibernate in mind?

3) How long have you been working with nhibernate?

To start off:

1) 523 tables mapped to 523 domain objects defined as partial classes, business logic in another partial class for each object (when needed), etc, etc -- the hope is to eventually move the logic from 1300+ stored procedures to business objects

2) Started with a pretty well designed legacy schema, the last 100 or so tables have been with nhibernate directly in mind

3) Since April '06

A quick question. You map association table as a domain object as well?

Yes we do, it seems to make things more straightforward and consistent, and a good number of our association tables provide the need for additional business logic.
How are you mapping association tables?
