I have noticed for an app to work Users must have permission to access whatever is being used for a database.
What if we want to keep the information that is in the database as a whole from people? Is there a way for the user to only be able to see what the app lets them see, instead of having the ability to open an entire SharePoint , Excel?
The reason being, is that we really don't want people seeing everything in the database. Also some of our excel workbooks are 50+ pages of custom calculations we would like to keep private.
