Hello Amien,

with PowerPivot you can load millions of rows of data, extending the standard Excel 2010 limit of 1,048,576 rows of data.

You can combine data from multiple sources, i.e. spreadsheets, databases (SQL Server, etc), create relationships in PowerPivot that don't exist in your source data, combine it with data in your Excel sheets, and more.

Then you can use the splice and dice (and sliders) functionality of Excel Pivot tables and pivot charts to create reports on your data.

I don't know "Qlikview", but PowerPivot has a lot of potential for creating on-the-fly reporting capabilities for people who are not trained as BAs and do not rely on the typical BA reporting tools like SSRS and the like.

With PowerPivot, you just point at your data sources, load an absurdly large amount of data and get it processed in a Pivot table in a snap. So far, what I have seen, PowerPivot out-performs Crystal Reports, SSRS, Business Objects, and many other tools.

And, publishing an interactive, dynamic reporting tool on SP 2010 is a snap, if your environment is set up accordingly.

cheers, teylyn

but the preperation of data is still needed in SQL.

In qlikview you have an advanded load script. With powerpivot you just read the data raw from the source?

for example .. is this easy to do in powerpivot: load values and put those values in a bucket and use that bucket in pivot charts? like 0-10,10-20 etc

it seems with powerpivot that i still need to build SQL view to make the nessessary data preperations.

You can use the standard pivot table tools to group your data in to buckets of 0 -10, 11-20, etc. That is standard pivot table stuff and has nothing to do with PowerPivot. PowerPivot just extends the range of your underlying data.

PowerPivot gives you access to a much larger data set than you can ever get with plain old Excel, enabling you to combine and link several distinct data sources, creating links and relationships. Once these data sources are organised in your PowerPivot environment, you can use the full range of Excel Pivot Tables and Pivot Charts for reporting, including grouping, slicers, and what not. Of course, the (sadly still present) limits of Pivot Charts still apply.

You need to understand that PowerPivot provides you with a much wider data base than native Excel ever can. After that, the added value lies in the ease of use when publishing PowerPivot reports to SP 2010, given you have the Enterprise license with the whole package.

on your last comment .. this all can be quit expensive:

you need SP 2010 including Enterprise CAL licenses PLUS SQL server including CAL licenses.

i'm sure Microsoft can offer a package deal. Allthough Powerpivot itself is free, it can be quit expensive
