DSA Cloud AD Context Diagram

Report & Distribution Commands are easiest to maintain in Microsoft Excel.  The commands in Excel are transferred to DSA Cloud AD using  DataSelf's ETL+ (or in some cases Microsoft Excel with Devart for Excel Add-on) installed on a server or Windows desktop at your site.  The Add-on allows Report & Distribution Commands to be maintained remotely.

AD Commands Database stores the Report & Distribution Commands table which drives the operations of DSA Cloud AD.

The Tableau Web Server can be hosted anywhere.   DSA Cloud AD can work remotely with Tableau Web Server over the internet.
