PowerPivot
27. Oktober 2010
Format:Taschenbuch|Von Amazon bestätigter Kauf
Practical PowerPivot & DAX Formulas for Excel 2010 is your standard How-to. From the title I expected a little more, and while my rating and this review sounds like a slam, its not. The book is a simpple block and tackle how to use. It well structured but not especially engaging. It reads like a reference text or the user's guide that should come with the product.
With that said, If you're looking for deep insights, cleaver tricks, and interesting examples or fluffy graphics this is not the book. If you're looking for a straight how-to, this is dead on. While I rate it a 3, I'm a very hard reviewer as I go up the scale. If you ask would I purchase the book again or was it a good value, I'd say yes again to both.

Good insight into Powerpivot - book title is accurate
11. März 2011
Format:Taschenbuch|Von Amazon bestätigter Kauf
Before I concidered purchasing this book, I already owned three powerpivot books. All were rated close to 5 stars by prior reviewers. I was not excited about yet investing in a fourth book, but I still struggled to identify and use functions available with the feature rich power pivot product. After reviewing the limited previews of this book available on Amazon, I was torn but finally decided to take the plunge in yet another purchase.
Wow, on day one I am using several of the 250 practical DAX formula's. One example is creating "running totals". Searching "running totals using power pivot" on google resulted in identifying complex solutions using the Calculate function. But when reading this book, I find a simple answer, the TotalYTD function! Then I needed to calculate the "percentage of a column" and a "percentage of a parent". Right there in chapter 12. The associated graphics helped immensely when trying to understand the variations of these calcuations.
Of all the four Powerpivot books I now own, this is by far my favorite as it is to the point, easily identifies features that are not readily apparent and helps clarify how to use functions making it very "practical" as the book title states. I carry this book with me to and from work everyday. Best $26 I have ever spent - great price for an excellent new book on Amazon. Now that I own the book, would have spent much more.

Your PIVOT POWER 2010 Excel Formulas Practical
28. Mai 2012
Format:Taschenbuch|Von Amazon bestätigter Kauf
Generally informative book. The author is without question an expert at data analysis and its management. In fact so much that he cannot resist to to digress into MDX, data cubes, SQL, and various other sophisticated data analysis methods. His side-trips make the book less readable and leaves the reader questioning his focus. While the non-DAX matters discussed are very informative, it would appear that the writer could have possibly handled these digressions either as footnotes, or as Appendixes. The book already contains 3 Appendixes and the subjects covered therein are at times repetitive of information covered earlier in the book.
The author could make his book far more readable by citing the navigational instructions in more logical sequence and format. For example, if a command is located buried in the Ribbon, why not start with what the reader sees and drill down from there. The writer seems to prefer to use the quite the opposite, the "drill up" method, which makes the book less readable and forces the reader the do mental gymnastics. Highlighting the COMMANDS in BOLD, or ITALIC letters or some other similar way, even if just capitalized, would make reading much easier by separating the navigational instructions from the text.
The book could certainly have been more readable had the author not wrote it in second person. As it is now, the reader suffers through, or attempts to ignore, hundreds of pronouns .. YOU and YOURS, not one of which advances the thesis of the book. Expecting the reader to read "your data".. and "you do this" .. "you do that" gets boring rather quickly, especially when some sentences contain 3 or 4 "you-s" and "your-s". (If you had to scratch your head with your hand, when your eyes saw the jumbled order of words in the review title, it is intentional and intended to draw attention to the awkward, illogical manner in which command navigations are handled in the book.)
The writer represents that the reader can download from a cited website 250 DAX formulas. The formulas download into .txt formatted documents with no explanations, or any further advice. It is not quite clear from the book how exactly the reader/user benefits from downloading them. The formulas appear to have been formatted to be used with the various data tables and databases discussed in the book.
Discounting the aforesaid organizational and writing style deficiencies, the book is well worth reading; it is certainly a very valuable, very useful reference manual on the subject of DAX formulas; and its price is most reasonable.
I am glad to have bought and read the book for it certainly gave me a good insight, into DAX and will keep it within reach as delve into Business Intelligence type analysis using DAX formulas, and POWERPIVOT in EXCEL 2010.
