• A report is one or more pages of visuals built in Desktop over one dataset. It is interactive and it is where the analysis lives.
• A dashboard exists only in the Service. It is a single page of tiles pinned from one or several reports, so it can pull from more than one dataset.

Camm's definition of a data dashboard is the concept behind both: a set of visual displays of the KPIs a decision maker needs.
