Relations create associations between objects in a catalogue. These associations define the structure of the publication.
For example, a catalogue contains two objects:
• An NTC_GEN (General Notice) object.
• An NTC_GENERALINSTRUCT (General Notice Instruction) object.
The two objects are components of a publication but are not automatically associated. A relationship must be established between them.
In this case, the NTC_GENERALINSTRUCT must be linked to NTC_GEN to create a General Notice Instruction for a General Notice. NTC_GEN is the source or parent object and NTC_GENERALINSTRUCT is the target or child object.
There are three types of relations:
Relation | Description |
|---|---|
Association | The loosest relationship type that defines a simple connection between objects. No object is dependant on an other for its existence. There is no parent/child relationship. |
Aggregation | A relationship of an object to a collection of objects. The objects in the collection may also be included in other aggregations so that objects are shared. For example Notices can be included in more than one publication such as weekly notice publication and a quarterly re-issue of active notices. |
Composition | The parent or source object is made up of or composed of child or target objects. The objects in the composition are not shared with other objects. If the parent object is deleted then child objects are also deleted. |
Relationships within a catalogue should match the publication structure.
For additional information on catalogue relations, see Relations.
