Update Mode
JADE guarantees database consistency by automatically maintaining inverse references.
If a Book is checked out to a Borrower, automatically JADE will add
the Book to the Borrower's myBooks collection.
Allowed update mode settings are one side manual and the other automatic,
or both manual/automatic. |
Relationship Type
If you set Borrower as the parent then Book automatically becomes the child.
Deleting a parent object triggers the deletion of associated child objects.
In a peer to peer relationship, deleting a Book or a Borrower object
does not cause the associated Borrower or Book objects to be deleted. |
