Provides access to members that are used to set up joins.
This interface is used to to manage joins on a layer.

DisplayRelationshipClass | Sets a join based on the specified relationship class and join type. |
 |
JoinType | Join type for the most recent join performed. |
|
RelationshipClass | Relationship class that defines how the tables are joined. |
| CoClasses and Classes | Description |
|---|---|
| CadAnnotationLayer | An Esri Cad annotation layer. |
| CadastralFabricSubLayer | Cadastral Fabric Feature Layer Object. |
| CadFeatureLayer | Esri CAD Feature Layer class. |
| CoverageAnnotationLayer | An Esri coverage annotation layer. |
| DimensionLayer | A collection of properties for a dimension layer. |
| FDOGraphicsLayer | A collection of properties for an annotation layer (feature data object graphics layer). |
| FeatureLayer | A collection of features and their visual representation. |

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.
