An association describes the relationship between two entities. In a Corticon Vocabulary, you can define the association under either entity. By default, the association that you define appears under both entities in the Vocabulary tree.



There are four types of associations:

  • One-to-many—If a vehicle can contain many cargo containers, from the perspective of the Vehicle (source) entity, the relationship with the Cargo (target) entity is one-to-many. A one-to-many association’s icon is a single bar diverging into multiple branches.
  • Many-to-one—From the perspective of the Cargo (source) entity, the relationship with the Vehicle (target) entity is many-to-one. A many-to-one association’s icon shows multiple branches converging into a single bar.
  • One-to-one—If a vehicle can have only one driver, the relationship is one-to-one. This is true from both perspectives. A one-to-one association’s icon is a single bar.
  • Many-to-many—Multiple workers may be assigned to load multiple vehicles through the workday. Each worker may load multiple vehicles, and each vehicle may have multiple workers assigned to load it. A many-to-many association’s icon shows multiple branches converging to a point from both sides.
