Entity Type: Relationships
General
You define a relationship between two entity types by specifying the two entity types involved, that is the source entity type (independent or referenced entity type) and the target entity type (dependent entity type). The relationship is oriented, proceeding from the referenced entity type to the dependent entity type.
In the Data Modeler a distinction is made between the ingoing and the outgoing relationships of an entity type:
Ingoing relationship
In this case the selected entity type is the target entity type (dependent entity type) and the other entity type the source entity type (independent or referenced entity type).
Outgoing relationship
In this case the selected entity type is the source entity type (independent or referenced entity type) and the other entity type the target entity type (dependent entity type).
