Data are physical or information items that are created, manipulated, or otherwise used during the execution of a process. You can create data objects in collaboration and process diagrams.
Note: PowerDesigner does not support the association of data objects with sequence flows.
The following kinds of data are available:
| Symbol | Description |
|---|---|
 |
Data object - Information flowing through the process. |

Data store - Place where the process can read or write data, such as a database or filing cabinet, and which persists beyond the lifetime of the process instance. |
Note: You can change the type of a data object by selecting a different stereotype from the Stereotype list on the General tab of its property sheet, or by right-clicking its symbol and selecting the appropriate Change to... command.
