5.6. Configuring Relationships Between Data Objects

When an attribute type is defined as another Data Object, the relationship is identified and defined by the symbol in the object attribute list. You can jump to the Data Object definition to view and edit by clicking on the icon.
Relationship customization is only relevant where the data object is persistable.
Relationships can be configured by selecting an attribute with a relationship and choosing the Persistence button on the right. Under Relationship Properties, click the Relationship Type property editing option.
Attempting to delete a Data Object that has a relationship with another Data Object will show the Usage Detected screen. It is still possible to delete the object from here, however this will stop your project from building successfully until the resulting errors are resolved.
