How is a join different than a relationship class?
Relates owned by the join table are not affected by the join. These relates can’t be accessed by the target table or layer, however. Relationship classes are never removed as a result of a join or unjoin operation. They can be used regardless of whether the data has been involved in joins or relates.
What is a relationship class in Arcgis pro?
Relationship classes define relationships between objects in the geodatabase. These relationships can be simple one-to-one relationships, similar to what you might create between a feature and a row in a table, or more complex one-to-many (or many-to-many) relationships between features and table rows.

How is a many to many relationship class created?
For many-to-many relationship classes, a new table is created in the database to store the foreign keys used to link the origin and destination classes. This table can also have other fields to store attributes of the relationship itself that are not attributed to either the origin or destination class.
Is it possible to edit a relationship class?
Regardless of how deeply chained, all the related classes are available for editing. Because relationship classes are stored in the geodatabase, they can be managed with versions. Versions allow multiple users to edit the features or records in a relationship at the same time.
