Presentation of Power Pivot

Power Pivot is a new tool of Excel 2013 that allows you to perform calculations on an unlimited number of rows. The calculation can be done with calculated columns, like in Excel, or with measures.

It all starts with SQL Server

Before to explain how to use Power Pivot, it is important to know that this tool has been developed by the engineers of Sql Server.

SQL Server is a relational database management system developed by Microsoft. It’s interface is SQL Server Management Studio (SSMS). When you use SSMS for the first time and when you are familiar with worksheet, you will be surprised to not visualize your data like you can do with Excel.

In fact, your data are stored, somewhere, but to visualize your data, you have to create a sql query.

So, to visualize the data like in Excel, the Microsoft’s engineers have developed a tool call SQL Server Analysis Services (SSAS)

When you link SSAS to a database, you can see easily the contain of each table like in a spreadsheet. But the data are in View only mode

SSAS = Power Pivot

At this step, Microsoft has created a tool to connect to database without limitation of rows. That’s the perfect tool to avoid the limitation of Excel.

So, in 2011, Microsoft has integrated SSAS to Office. And because the only way to return the results is in an agregator, and the only agregator of Excel is Pivot Table, SSAS becomes Power Pivot in Office (logic).
