Interface BusinessObject

public interface BusinessObject

Implemented by top-level Entity Objects that aggregate Entity Objects.

Aggregation (also known in UML as composition) unites Entity Obejcts related by a composition association. For example, if a composition association is defined between Entity Obejcts `Dept` and `Emp`, then `Dept` can be identified as a top-level Entity Obejct by implementing this interface for the `DeptImpl` class.

This interface is not used in the JDeveloper 3.0 framework: it is provided for use in applications.

Since:
  JDeveloper 3.0
