===== Object relation type =====

There are two relation types: **peer** and **ownership**. The peer relation type should be used for objects that can exist independently of each other. For example a product can exist without being linked to a product category. If a product category is deleted, all products that were linked to the category lose the link but continue to exist on their own.

The ownership (or parent/child) relation type should be used if an object belongs to some other object and does not make sense without its owner object. For example, a line item always belongs to an order. If an order is deleted all line items of that order should be deleted as well. If a [[glossary:configurator|configurator]] marks a [[glossary:reference_attribute|reference attribute]] of an object as owned by another object, **//[[glossary:aware_im]]//** will automatically delete the object when its owner object is deleted, or when the link with the owner object is broken.
