The type of relationship that links two objects together, but has no effect on deletion, record ownership, or security, and the lookup relationship field is not required in the page layout is a "Lookup Relationship."

A Lookup Relationship is a type of relationship between two objects in Salesforce where one object (the "child" object) has a field that references another object (the "parent" object). This relationship allows users to create a link between the two objects, allowing them to access related information.

In a Lookup Relationship, the child object has a field that contains a reference to a specific record in the parent object. However, this relationship does not enforce record ownership or security, nor does it impact record deletion.

Unlike a Master-Detail Relationship, which requires a "Master-Detail" field on the child object to be displayed on the page layout, a Lookup Relationship field is not required on the child object's page layout. This means that you can create a Lookup Relationship without adding any fields to the child object's page layout.

In summary, a Lookup Relationship is a simple way to create a link between two objects in Salesforce without enforcing any special rules for record ownership or security. It is useful when you want to show related information from another object, but don't need the extra functionality that comes with a Master-Detail Relationship.
