Hi Andy,

I'm a little confused about Power BI.  Looking at your videos, it seems Power BI is a collective term for PowerPivot, Power Query, Power Map, etc.

However, googling Power BI, I see this, where the video shows a completely independent tool aimed at creating dashboards and reports, so can you please clarify what is Power BI?  Thanks.

Microsoft haven't helped with their naming convention!  They keep changing what Power BI refers to.  Here's where we're at now ...

Power BI is a standalone desktop product, previously known as Power BI Desktop.  You can use these to create reports, and publish them to the web.

PowerPivot runs within Excel, and allows you to link different data sources together to create a data model, and use this as a basis for pivot tables.  PowerPivot used to be one of the Microsoft Power BI tools, but they seem to have quietly dropped this title.

So when Microsoft refer to Power BI, they now refer to creating reports in the standalone Power BI application, perhaps using Power BI Pro, and publishing these to the Internet.  

Hope that's clear ... !
