Business Modeling diagrams and Business Interaction diagrams enable you to model both the structure and behavior of a business system.
Business Modeling diagrams are based on a Class (UML Structural) diagram, whilst Business Interaction diagrams are based on a Sequence (UML Behavioral) diagram. Both diagram types have the same default Toolbox, which consists of a Business Modeling element page. The available elements include stereotyped Objects, and a stereotyped Actor (Business Actor), Use Case (Business Use Case) and Collaboration (Business Use Case Realization).
