Answers
Cascade:  enable operations to cascade to child entities.
cascade=”all | none | save-update | delete | all-delete orphan”
all: when an object is save/update/delete, check the associations  and save/update/delete all objects found.
none: do not do any cascades, let user handles them by themselves.
save-update: when the object is saved/updated, check the associations and save/update any object that require it.
delete: when the object is deleted, delete all the objects in the association.
all-delete-orphan: when an object is save/update/delete, check the associations and save/update/delete all objects found. in addition to this, when an object is removed from the association and not associated with another object, delete the orphan object also.   Your Comment
