Apartment Building Architecture and NHibernate

Question

Can someone finally explain to me what is the best strategy for implementing transparent and smooth support for multi-user functions in a NHibernate powered domain model?

Im looking for a way to keep the domain logic as isolated from multiuser things as possible, such as TenantID filtering, etc.

Answer 1

The easiest way is to use different databases for each client.

Implementing multi-user access in this way allows you to efficiently write one tenant application and only worry about multi-user work in the place where you create / retrieve the session.
