No more delays!

Awhile back I reviewed Mr. Excel’s PowerPivot book and vowed to post a review of the other major PowerPivot book to date, by Denny, Ron, and Siva (all from the SQL team at Microsoft).

I actually finished this book awhile back, but things got pretty intense at Pivotstream (in a good way), delaying my writeup much longer than intended.

So, no more delays, time to dive in and tell you what to expect.

Focus on The PowerPivot System

In my review of Bill’s book, I said that there was no better primer for Excel pros making the transition to PowerPivot, and that remains true.  Bill took the approach of “this is the greatest thing to happen to Excel in over ten years, so Excel pros, listen up, you’ve got an arsenal of new tools to deploy.”  And I think that is precisely the right approach to take with Excel pros who are getting started.

But there are MANY other aspects to PowerPivot, and a lot of ground left to cover in depth.

The boys from Redmond have VERY different backgrounds from Bill, and those backgrounds shine through in their book.  You could almost read their book and Bill’s book and not be sure they were discussing the same product… and I think that is a very good thing.

Cutting to the chase, the Red book (I’m gonna call it that for short) covers a lot of things that the Bill book intentionally leaves to others:

  1. How PowerPivot compares to and interacts with traditional BI systems
  2. What it takes to implement an entire PowerPivot SYSTEM in your organization
  3. The technical underpinnings of PowerPivot, both in Excel and SharePoint
  4. A quantity of hyper-detailed tips and tricks that can only come from insiders
  5. Integration with a wide variety of data sources
  6. Planning and deploying a PowerPivot for SharePoint farm
  7. Monitoring and maintaining your SharePoint deployment
  8. Also covers a LOT of the basics of SharePoint, useful for SharePoint neophytes

What the book is NOT

1) It is not the first book an Excel pro should pick up.  It covers too much, and comes from a perspective that might seem a bit foreign.  Start with Bill’s book if this is your background.

2) Like Bill’s book, it is only a light treatment of DAX.  Again, this is wise, because DAX really deserves its own book.  Those seeking a detailed DAX book should look forward to an upcoming title from Marco Russo.

3) It does not cover the real-world gotchas encountered in a full adoption of a PowerPivot system.  After a full year of applying PowerPivot to real-world problems – six months as a product team member in exile (in Cleveland), and the last six months putting the full system into action at Pivotstream, I can say that there are a number of “gotchas” that you have to look out for in PowerPivot v1.  They are not fatal – Pivotstream’s PowerPivot platform is very much thriving – but you only discover them, and learn to avoid/overcome them, via real-world practice.

Anyway, for a just-released product, it’s not like we can expect ANY book to cover that kind of thing.  There’s probably room for a book like “PowerPivot in the Trenches” but someone else needs to volunteer, as I, um, rarely get out of my trench 🙂

What the book IS – Consistently readable and info-rich

1) Great Information Density, but High Readability – When I finished the book, I immediately dropped an email to Denny/Ron/Siva and told them how impressed I was with the balance between density and clarity.  As a de facto tech writer myself throughout my career, I can say that I struggle with this, and typically end up jamming in too much at the expense of readability, or a 50-page doc with so much whitespace that 20 pages would have covered it.  Perhaps you have noticed.

It’s hard to put my finger on how the book strikes such a nice balance – perhaps it’s the editing, or the layout style – but I consistently noted how MUCH was conveyed on each page, while at the same time, it felt like a light read.  That’s saying a lot considering the list above.

2) Benefits of Three Product Team Authors – When you include all of the folks from teams like SharePoint, Excel, SSRS and others that contributed to PowerPivot, it’s probably safe to say that the product reflects the efforts of 200+ people for several years.  No one human being could possibly span all of that, and it only gets harder if you weren’t directly involved in that process.

These three guys were working on the book for a long time, while the product was still in development.  They all had different areas of focus, both in terms of natural affinities and in terms of dividing up their assignments.  They then had a lot of time, and access to the people who were building the product, to refine the content.

And then they all rigorously cross-reviewed each others’ chapters – you can’t get away with slips and omissions when two of your peers are on you, and they have the same level of exposure and access that you do.

The benefits of this authorship approach are evident in the book.  You’ll see what I mean – I always expect some “uneveness” in a tech book of this length because the talents and endurance of a single author are themselves uneven.  Chapter to chapter, the red book’s quality remains consistent.

3) History of PowerPivot.  The book is sprinkled with a number of sidebars titled “Inside PowerPivot” that relate some of the human side of how the PowerPivot project got started, and evolved over time.  While not actionable in a technical sense, other people that I’ve talked to about this book, without exception, the first thing they say is how much they enjoyed these sidebars.  That’s saying a lot given the two points above.

Overall Recommendation

If you fit any of the following descriptions, I rate this book as a must-read:

  1. Anyone leading or contemplating a PowerPivot deployment (the total system, as opposed to just viewing it as Excel 2010++)
  2. Excel pros who have read Bill’s book and want to expand their expertise – I suspect a lot of you will decide, correctly, that a full PowerPivot system makes your talents a lot more valuable and visible, and will find yourselves on point for test deployments
  3. BI or SharePoint pros who are ramping up on PowerPivot (or evaluating PowerPivot’s impact on their work)

  1. Thanks Rob. I don’t disagree with anything you write. One of the big thrills for me of working on PowerPivot since its inception is when an internal customer shows our team what they’ve implemented with it and their app lines up exactly with what we wanted the product to be when it was still a gleam in our eye. IMO, your review gives me a similar feeling in that I think it captures what we were thinking back when we planned the book. To focus in on what you say in the “What the book is NOT” section (since you call it out), I’d say it’s pretty right on. Given the short timeline of the product (re. point 3) and our background and experience (re. point 1) it’s “by design.” I would also say, WRT point 2, that DAX does deserve its own book-length treatment and it’s fair to say our book is light in that area.

    One of the cool things about the PowerPivot book scene (published as well as coming) is that they each have their own place – we’re not all trying to write the same book. Thanks for taking the time to review our contribution to that space.

  2. In my opinion Power Pivot is a piece of Junk. I have built thousands of Pivot Tables using the regular pivot table with SQL server or Cube as data source and I can build a pivot in less than a minute. While Power Pivot takes forever to import stuff and then even while building the pivot, the power pivot is very very slow. (NOTE: I tried power pivot on Win XP 32-bit machine with 2GB Ram)

  3. Hi Veeram. Clearly our experiences differ – at Pivotstream we literally run our entire business on PowerPivot, and our data volumes are immense (sometimes greater than 100 M rows), combined with complex measures that you could never build in vanila Excel.

    A few potential sources of problems for you:

    1) 32 bit with so little RAM is a very likely source of trouble. The addin and the PowerPivot engine DO chew up a lot of RAM. And at import time, there’s a pretty sizeable spike in RAM consumption. If you were running even on a 32-bit machine with 4 GB RAM, I suspect you might have a VERY different experience.

    2) PowerPivot does introduce some fixed-cost overhead in certain operations that Excel does not. Examples: a) on data import, there is time spent on compression. b) when adding a field to the data area of a pivot, or creating a new measure, there are update steps in the background plus a full refresh triggered. c) when you add calc columns, again, there is a compression step.

    That’s the bad news. The good news is that these fixed costs don’t linearly scale up as data volume scales up. So a calc column on a 100M row table does not take all that much longer than on a 10k row table. Weird but true.

    The other good news is that those fixed-cost investments lead to huge payoffs in perf as data volumes get larger, as well as file size improvements.

    Once you have a machine with a decent amount of RAM (and 64-bit is required for truly large data volumes, say > a few million rows), and start experimenting with advanced measures and/or larger data volumes, I really do believe your experience will change significantly.
