DAX Studio for Excel 2013 finally available! #dax #excel #powerpivot #ssas #tabular

sqlbi — Sat, 04 May 2013 05:49:00 GMT

I'm so happy that DAX Studio finally supports Excel 2013! As Darren Gosbell described in his blog, this release has a few internal changes that will better support future enhancements. I will port the code to capture the query plan for a query in this new release, but unfortunately it will require some weeks because I'm traveling a lot in these days.

If you write DAX formulas and queries for PowerPivot or Analysis Services Tabular, DAX Studio is a must have tool: do you really want to live without a DAX Editor? There are a lot of possible improvements and I hope other contributors will give their help to this Codeplex project.

PowerPivot Workbook Size Optimizer #powerpivot #tabular

sqlbi — Tue, 30 Apr 2013 10:50:00 GMT

Microsoft released the Workbook Size Optimizer for Excel, the first version of an Excel add-in for Excel 2013 that inspects the data model and suggest possible optimizations. Fundamentally, it tries to apply the best practices descripted in a white paper I mentioned a few weeks ago, removing useless columns and changing granularity to those that could reduce the overall memory cost of a table.

There are different setup available in the download page, depending on operating system (Windows 7 or Windows 8) and on Office version (32 or 64 bit). Once installed, you have a new tab in the Excel ribbon, called Workbook Size Optimizer, showing a single button that starts a wizard.

I tried to run the optimizer with a workbook where I imported several tables from Adventure Works Data Warehouse sample database. The first page shows a few information about the workbook size and the option of automatic detection or manual choice of rules. The latter is an option you can request also later, so I started with the default.

After a short analysis, I received three smart suggestions (considered the model I have). We might wonder that removing UnitCost is a smart thing, because it could be required in order to perform calculations and rounding the value might be not correct for our analysis.

Since I requested to apply some changes, I have the option of changing which rules to apply. This corresponds to the choice you have if you choose “Let me choose the rules myself” in the first screen of the wizard.

I kept all the rules and after I click Next I had to wait several seconds in order to complete the optimization process. The result shows a few information about the result of the job.

This is a good starting point. Don’t blindly trust any suggestion and try to consider carefully the rules to apply in order to avoid losing important data for your analysis. Moreover, you might have a better knowledge of your data model than a wizard and consider the deletion of many useless columns (for your analysis) that are not identified by the wizard. My article Checklist for Memory Optimizations in PowerPivot and Tabular Models contains several best practices that you can apply to your data model.

New PowerPivot 2013 book available! #excel #powerpivot

sqlbi — Tue, 02 Apr 2013 11:25:00 GMT

Our new book about PowerPivot 2013 is finally available in printed edition, too!

The title is Microsoft Excel 2013: Building Data Models with PowerPivot and it is a partial rewriting of the previous book about PowerPivot for Excel 2010. In the previous book we had a target audience that included advanced Excel users and BI developers, because at that time there was no option to get the same engine in Analysis Services. But 30 months are elapsed, a new version of Analysis Services has been released and in this new book we focused mainly on Excel users. For this reason, we wrote a comprehensive book of all the feature of PowerPivot, but most important we tried to pass concepts of data modeling that might be pretty obvious for a DBA and a BI developer, but are completely new to an Excel user that never had the ability to create a data model with more than one table.

This book is focused on Excel 2013, so we included specific feature of this release related to PowerPivot, such as writing DAX queries and linked back tables, and features unique to Excel 2013, such as Power View. However, all of the PowerPivot features (so the 85% of the book) are good also for PowerPivot for Excel 2010 in its latest release (SQL Server 2012 SP1 PowerPivot for Microsoft Excel 2010), so you can safely use this book for both version of Excel.

You can download the first chapter of the book from the book page on SQLBI web site. And if you want to attend a training in a classroom or online, look at the complete list of available trainings on PowerPivot Workshop web site. The next online courses are scheduled on April 22-24, 2013 and June 17-19, 2013 (following online workshops are every other month).

Here are the links to directly order the book on Amazon around the world:

And here is the list of chapters:

Chapter 3 Introducing DAX
Chapter 4 Understanding data models
Chapter 5 Publishing to SharePoint
Chapter 6 Loading data
Chapter 7 Understanding evaluation contexts
Chapter 8 Understanding CALCULATE
Chapter 9 Using Hierarchies
Chapter 10 Using Power View
Chapter 11 Shaping the Reports
Chapter 12 Performing Date Calculations in DAX
Chapter 13 Using Advanced DAX
Chapter 14 Using DAX as a Query Language
Chapter 15 Automating Operations Using VBA
Chapter 16 Comparing Excel and SQL Server Analysis Services

This book should help you starting with PowerPivot at the very beginning, and you will probably use only the first chapters at that point. Over time, you will use following chapters and will learn more advanced techniques. This is not a book you can digest in a couple of days (after all, it is 500 pages long!), it will be your companion for several months, until you will master PowerPivot!
