Interaction Toolbox

The Interaction Toolbox is used to develop Sequence diagrams. You use Sequence diagrams to model dynamic interactions - work flow and the sequential passing of messages - between elements in real time. Sequence diagrams are often placed beneath Use Case elements to further expand on Use Case behavior over time.

Except where discussed here, each element and relationship that you can create using these Toolbox pages is described in the UML Elements and UML Connectors sections of the Help.

 

A Boundary is a stereotyped Object that models some system boundary, typically a user interface screen.

A Control is a stereotyped Object that models a controlling entity or manager.

An Entity is a stereotyped Object that models a store or persistence mechanism that captures the information or knowledge in a system.

Notes

The Interaction element supports the capture of Interaction diagrams through the Project Browser and diagram context menus; you cannot capture  these diagrams by dragging the element onto a diagram
The Fragment icon creates Combined Fragment elements
Message, Self Message and Call are described as Sequence diagram messages
Messages can be simple or recursive calls
To add an element to the currently-open diagram, click on the appropriate icon and drag it into position on the diagram; set an element name and other properties as prompted
To add a relationship, click on the appropriate icon, then click on the start element in the diagram and drag to the end element
