Excel: Power-Pivot (menu)

In order to have Excel show the Power Pivot tab on the Ribbon bar, the Data Analyis add-in must be enabled. This can be done using the menu Data -> Data Tools -> Manage Data Model.

Alternatively, it seems that Power Pivot can also be enabled using the COM Add in Microsoft Office PowerPivot for Excel 2013.

Elements that are found on the Power-Pivot Ribbon are:

Data Model	(TODO: See Data Model)
Calculations
Tables
Relationships
Settings	(which is not really an «element»)
