Question

What is junction object in salesforce

Answer 1

Junction object in Salesforce is a custom object with two master-detail relationships, typically linking three objects together. Junction objects are used to model many-to-many relationships between two objects.  A junction object contains two master-detail relationships, each linking to a different standard or custom object in Salesforce. Junction objects provide a flexible way to model complex relationships without creating direct many-to-many relationships.
