Your mobile device can directly interface with SalesForce, using visually created query commands in a graphical tree. The query commands include insert, update, select and delete.
These commands will run when a user taps a button or table row on your device.
To enable your app to connect to SalesForce Objects, your SalesForce account needs to have a registered API and your mobile app needs to know some of the API information :
When you are done registering your API for SalesForce, go to your ViziApps Studio and create a Data Source ID.
