We reviewed what BI is and why it's important. We've also identified many of the tools that you probably already own and may even have installed.

Most of this book will be using the Power BI tools for Excel from Microsoft. With so many companies using Excel on a daily basis and so many of them using Excel for BI, we thought this is probably your tool of choice. Keep in mind that when we use Excel, we'll be creating a refreshable report, not just another Excel file that holds data. What does this mean? Excel will hold the formatting and the link to the data, and the data can be refreshed or updated when you need or want it.

On your marks, get set, go!
