Study Notes

Different Relationship Types in Salesforce

Salesforce relationships connect objects, linking data.
Lookup relationships are loose connections.
- One object references another.
- Deleting one doesn't affect the other.
- Example: Contact referencing an Account.
- Not mandatory for a related parent.
- Child records are separate.
- Up to 40 lookups per object.
- No roll-up summary fields.
Master-Detail relationships are tight connections.
- Deleting a parent deletes child records.
- Example: Account and Opportunity, if the account is deleted, all opportunities linked to that account are also deleted.
- Parent is required for child records.
- Deleting the parent also deletes the child.
- Allows roll-up summary fields (like sum, counts).
- Up to 2 master-detail relationships per object.
Hierarchical Relationships are a lookup type.
- Only for User objects.
- Manager-employee structure.
- No roll-up summary fields.
Many-to-Many Relationships connect multiple records through a junction object.
- Multiple records from one object can be related to multiple from another.
- Uses a junction object (custom).
- Example: Students and courses (through a course enrollment).
- Supports roll-up summary fields.
External Lookup Relationships link Salesforce objects with external systems.
- Used to integrate data from other databases.
- Example: Salesforce Order Object linked to an ERPOrder.
- Up to 25 external lookups per object.
- Requires unique identifiers for linking.
