Data storage depends on the data table type (Published, Saved and so on), and the connection type (Database, Excel, CSV, and so on). Specifically:
q Database (relational and tick history) or Message Queue
No physical data storage.
q Flat Files (Excel, CSV, Text, XML and SVG)
If configured as a saved data table / workbook, no copy of the spreadsheet is made; instead, the path to the original file is stored, allowing updates to be accessed.
If the data table / workbook is published, a snapshot of every defined Excel spreadsheet is copied to the server. To update a published spreadsheet, the data table must be again connected to the source spreadsheet and then re-published.
