Universal Containers’ Platform Administrator has been asked to create a many-to-many relationship between two existing...

In Salesforce, a many-to-many relationship allows each record of one object to be linked to multiple records of another object and vice versa. This is achieved by using a Junction Object. A junction object is a custom object that sits between the two objects you want to relate. To implement this correctly, the administrator must follow two specific steps: first, create the custom object to serve as the " junction " ; second, create two Master-Detail relationship fields on that new junction object. One master-detail field points to the first custom object, and the second points to the other. Because these are master-detail relationships, the junction record ' s visibility and deletion behavior are controlled by its parents. This structure allows for powerful reporting and roll-up summaries on both parent objects. Using simple lookup relationships (Option D) would not enforce the strict data integrity or the specific roll-up capabilities that define a true many-to-many relationship in the Salesforce architecture.
