Notes
A junction relationship in Salesforce is used to create a many-to-many relationship between two objects. It works by using a custom object (called a junction object) to link the two objects together.
Example:
- Suppose you have two objects: Students and Courses.
- A student can enroll in many courses, and a course can have many students.
- To handle this, you create a junction object called Enrollment.
- The Enrollment object has two master-detail relationships: one with Students and one with Courses.
- This setup links students and courses, allowing you to track which students are enrolled in which courses.
This method is great for modeling complex relationships where simple one-to-many links aren't enough.
