A package-level relationship defines an association between the package and an associated target part or resource. A package-level relationship can be one of two forms.
Between a Package to a target resource outside the package.
In a package-relationship the package is considered the "owner" of the relationship. When the package is deleted, all the relationships owned by the package are also deleted. The process of creating or deleting the relationship does not physically alter the target part or resource in any way.
