Magento\Quote\Model\Quote\Address\Relation

What it does

This class handles saving related data (items and shipping rates) when a quote address is saved in Magento 2.

Developers typically don't interact with this class directly as it's automatically invoked by Magento's resource model layer during the save operation to ensure all address-related collections are persisted to the database.
