Lookup VS Master detail
|This is parent-child relationship||This links two objects together|
|Detail object is deleted when Parent is deleted||No effect on linked records|
|Parent can have Roll-Up Summary fields||Roll-Up Summary field are not available on lookups|
|Detail record must have Master record reference||Reference to linked record is optional|
|The detail record inherits the sharing and security settings of its master record.||Both linked records have independent sharing and security settings|
