Viewing and modifying relationship properties

Available with Standard or Advanced license.

Note:

Although relationship classes can be both created and edited in ArcGIS Desktop Advanced and ArcGIS Desktop Standard, they are read-only in ArcGIS Desktop Basic. The feature classes participating in a relationship class are also read-only in ArcGIS Desktop Basic.

Once you create a relationship class, it appears in the Catalog tree, and you can inspect the properties of the relationship class and the feature classes that participate in it.

You can set and change relationship rules, but the only general property you can modify in an existing relationship class is the name. To change properties other than the name, delete the relationship class and re-create it. However, if the relationship has many rules, it can be tedious to reestablish them. One way to make this process easier is to create relationship classes with reusable Unified Modeling Language (UML) model diagrams that can be modified and rerun.

You cannot change the properties of relationship classes or any other geodatabase datasets in ArcCatalog or the Catalog window if any of the geodatabase contents are being accessed in ArcMap or ArcCatalog. Exit any other instances of ArcMap and ArcCatalog before you make the changes.
