To restore the deleted Review records, you need to restore both the Account and Product master records from the Recycle Bin. A master-detail relationship is a type of relationship that links two objects together and enforces a parent-child relationship between them. A master-detail relationship affects the security and deletion of the child records. If you delete a master record, all of its detail and subdetail records are deleted as well and moved to the Recycle Bin. To restore a detail or subdetail record, you must first restore its parent record.
