What object relationships that are available in Salesforce do you know of?
- Lookup relationship: this links two objects together. It is the most basic type of relationship that exists on the platform.
- Master-detail relationship: this creates a strong relationship between two objects. If a master record is deleted, then the record associated with it will also be removed. They allow you to calculate data on the master record from the record associated with it.
- Many-to-many relationship: this allows you to link a child record to many parent records. This relationship is made with the help of a junction object.
There are many other relationships available in Salesforce, including; Self-relationship, External lookup relationship, Indirect lookup relationship, and Hierarchical relationship.
