Answer 1

Try look here:

NHibernate Cascades: the different between all, all-delete-orphans and save-update

or here:

Nhibernate Cascade

also here:

NHibernate Definitive Cascade application guide

update

Here you can find a great explanation of inverse:

Inverse Attribute in NHibernate

And those are cascade differences:

1. cascade="none", the default, tells Hibernate to ignore the association.
2. cascade="save-update" tells Hibernate to navigate the association when the transaction is committed and when an object is passed to save() or update() and save newly instantiated transient instances and persist changes to detached instances.
3. cascade="delete" tells Hibernate to navigate the association and delete persistent instances when an object is passed to delete().
4. cascade="all" means to cascade both save-update and delete, as well as calls to evict and lock.
5. cascade="all-delete-orphan" means the same as cascade="all" but, in addition, Hibernate deletes any persistent entity instance that has been removed (dereferenced) from the association (for example, from a collection).
6. cascade="delete-orphan" Hibernate will delete any persistent entity instance that has been removed (dereferenced) from the association (for example, from a collection).
