A recent addition to the updated exam guide from Salesforce, which they released on June 23, 2021 was Junction Relationships.
In this lesson, I discuss how to create a Junction Relationship between two objects, which is known as a Junction Object. This provides for a many-to-many relationship.
I show an example of a junction object that I created for my Career Launch Accelerator course, which is available at https://careerlaunchaccelerator.com
In the example, I have created a Resume Submission custom object. On that custom object, I have two Master-Detail fields. One master-detail field connects with the Opportunity object and the other connects with a custom object called Resume submission.
