Master-Detail relationships feature cascading deletion of detail records upon master deletion and support roll-up summary fields on the master object to calculate aggregate data from child records.

Adım Adım Çözüm

1
Analyze relationship deletion behavior
Identify that Master-Detail relationships perform cascading deletes on detail records when the master is deleted.
Detail record ownership and lifecycle are tightly coupled to the master record.
2

Determine that roll-up summary fields are exclusively available on the master object in Master-Detail relationships.
Lookup relationships do not natively support roll-up summary fields.
