Recently I've started a ‌BPMS project. I have read a lot about BPMN2 but I do not know exactly data objects and data store application.

In some cases data object is used to display files. For example in this diagram, Upload Expense Support File looks for a file but Data Input construct for modeling input data within the Process flow!!??

enter image description here

In other case data object is used to instance of Folio class (Folio table in database)

enter image description here

I'm confused. What is application of data object?

Thanks.

Data Stores are permanent. The information a process writes to a Data Stores is available after the process instance terminates.

Data Objects exists for the scope of the process. Only if a Data Object is defined as a Data Output Object it exists beyond the scope of the process.

So you should use Data Objects for explicit process inputs/outputs and documents that are created ad-hoc and later discarded.

Data Stores, should be used if your process creates, alters or consumes to generally persisting information.
