NHibernate Domain Mapper is a tool
that assists user creating NHibernate
Mapping Files. User may add his own
Domain Model assemblies and map
them to database table using a rich
UI, which will present him all the
suitable options regarding at the
element type he created. The
peculiarity of this tool is that it allows
doing the mapping task starting from
a domain model instead of a Database
schema.
