Remarks
ArcMap provides two ways to associate data stored in tables with the features in the layer: joins and relates.
When you join a table to the layer’s attribute table, you append the fields from the table to the layer’s table. Joins can be used for one-to one or many-to-one relationships between a layer and a table.
Relating the layer’s table with another table defines a relationship between the two tables, but it doesn’t append the fields of the table to the layer’s table. Relates can be used for one-to-many or many-to-many relationships between a layer and a table.
Use IDisplayRelationshipClass to set up and manage joins between a layer and other tables. Use IRelationshipClassCollection and IRelationshipClassCollectionEdit to manage relates.
