| * <p><b>Purpose</b>: Represent a employee of an organization. |
| * <p><b>Description</b>: An Employee is a root object in the Employee Demo. |
| * It maintains relationships to all of the other objects in the system. |
| * The employee shows usage of 1-1, 1-m, m-m, aggregate and transformation mappings. |
| * The employee also shows usage of value holder to implement indirection for its relationships |
| * (note, it is strongly suggested to always use value holders for relationships). |
