Description A Data Association is used to model how data are pushed into or pulled from item-aware elements. Tokens do not flow along a Data Association. Therefore, they have no direct effect on the flow of a process. Alternatively, Data Objects can be directly associated with a Sequence Flow to represent the same input or output Data Associations. This is a visual shortcut that is stored in a model as two Data Associations - from Activity to Data Object
- from Data Object to Activity
