Data Source Connection
Once the data model is built under Namespace, you need to fill real data to the model for subsequent processing and use.
- Under the Model tab, select the file.
- Scroll down to Topology, click the icon on SourceFlow to redirect to the generated data flow under SourceFlow.

- Change the data source of the generated flow.
info
Make sure the returned data of the source node is JSON object. Presently, supOS can only parse this data type.

- Delete the mock data node and connect the source node to the rest of the flow.

- Click Deploy at the upper-right corner, and then trigger the flow.
- Go back to Namespace, check whether the data is sent back to the file (data tag).
