- The identifying elements of the source entity in a parent/child are inherited and become identifying elements of the target entity.
- The inherited identifying elements are denoted by the symbol (*) on the diagram.
- The source and target end of the connector is important in determining which entity will be the parent (source) and which object will be the child (target).
- Subsequent parent/child relationships to the first parent/child relationship in a target entity will generate logical views in the target entity.
Tips and Techniques
- If an entity has more than one parent, define them in any order you wish. The inherited identifying elements can be re-sequenced at a later stage.
- Enter notes against elements. Notes will be transformed into field-level help text when the entity is built.
