class with the stereotype "business worker" ( ) and a business entity is a class with the

stereotype "business entity" ( .)The business object model can also identify

organization units in the business. An organization unit is represented as a logical

package with the stereotype "organization unit" ( .) The Classics, Inc. business is

Click the diagram tool.

 Click and drag the association from Online Order to OnlineCustomerProfile.



Add the Order entity to the diagram, by dragging from the Logical

View/Business Object Model/Inventory-Shipping Unit package in the browser onto

the diagram.

 Create a generalization relationship between Online Order and Order, by clicking

in the diagram toolbox. Make sure that the relationship points to Order.



Drag the business entity, located in the Logical View/Business

Object Model/Retail Stores Unit package, from the browser onto the diagram.
