Data Flow Icons

Two types of flow lines are allowed in activity charts: data flow lines, drawn as solid arrows, and control flow lines, drawn as dashed arrows.

 
Create Data-Flow - Establishes a data flow between two activities. Data flow lines carry information that is used in computations and data-processing operations
Create Control Flow - Establishes a control flow between two activities. Control flow lines carry information or signals that are used in making control decisions, for example, commands or synchronization messages.
Label Existing Flow Line - Enables you to name a flow line that denotes either a single information element that flows along the line or a group of such elements.
Flow labels in activity charts, module charts, and information-flow elements can be any primitive (variable) data element (event, condition, data-item) or information flow. In addition they can be elements on any level of a primitive data element (array element, array slice, and record/union field). Array elements can use only literal constants.
