What are Junction Objects in Salesforce?

Hi Rahul,

Salesforce Junction Objects are custom objects used to create many to many relationship between any two objects. A many to many relationship allow each record of one object to link with each record of another object and vice versa.For example,you may have a custom object called “Bug” that relates to the standard case object such that a bug could be related to multiple cases and a case could also be related to multiple bugs.

A Junction object is a custom object with 2 master detail relationships.

Creating Many to Many relationship consists of :

Creating the Junction Object
Creating the two master detail relationship

Thanks,

Hi Rahul,

In Salesforce, a Junction Object is a custom object with two master-detail relationships to two different record types. It is used to represent a many-to-many relationship in which several junction objects can link one instance of a record to many children.

Hi,

Junction Object is a custom object with two master-detail relationships. Using a custom junction object, you can model a “many-to-many” relationship between two objects. For example, you create a custom object called “Bug” that relates to the standard case object such that a bug could be related to multiple cases and a case could also be related to multiple bugs.

Creating the many-to-many relationship consists of:

Creating the junction object.
Creating the two master-detail relationships.
Customizing the related lists on the page layouts of the two master objects.
Customizing reports to maximize the effectiveness of the many-to-many relationship.

Thanks.
