Notes
A master-detail relationship in Salesforce is a type of association between two objects, where one is the 'master' and the other is the 'detail.' The master object controls the behavior of the detail object and owns its records. If a master record is deleted, all associated detail records are automatically deleted (cascade delete). This relationship allows for the creation of roll-up summary fields on the master object, aggregating values from related detail records. Security settings on the master object apply to the detail records, making it an essential feature for data modeling and maintaining data integrity in Salesforce.
