One potential "gotcha" (depending on when you read this) is that the book references some features (like Measure Groups and explicit aggregate tables) that are only available in Mondrian 4. This is explicitly noted; however, Mondrian 4 is not generally available (as of end of Jan. 2014), and the book talks about it as if it is already available. Worse, there is no information online re: when version 4 will be GA. So, don't be surprised if measure groups don't work for you.
The appendix is very good, but misses calling out the SimbaO2X driver, which lets you connect Excel and other products to Mondrian. Some BI users (especially in finance and marketing) prefer Excel as their BI front end, and that driver lets you leverage Mondrian for that use case
The first thing to note about this book is that it would have more appropriately been named something like Mondrian With Pentaho in Action. The Mondrian engine (which is open source) can be used in a stand-alone fashion or with another system, but the book focuses almost entirely (other than chapter 9) on using it with Pentaho (commercial open source-community and enterprise editions). This doesn't mean the book is only useful to users of Pentaho, since the majority of the material on setting up Mondrian, security and the data would be useful without Pentaho.
Things the book does well:
1. It does a good job of leading readers to the material they will want to read by providing a table (in the "about this book" section) of which chapters would be useful to which type of readers (Business Analysts, Data Architects, Enterprise Architects, Application Developers)
2. It contextualizes the material presented by giving some of it in story form
3. Lots of specific instructions on how to use Mondrian (code examples, schema examples etc)
Things the book does poorly:
1. Captions are embedded inline rather than being next to their associated figure. This may simply be because I was reading in on my iPad rather than as a hardcopy. Example: on page 9 there are descriptions of Figures 1.5, 1.6 and 1.7. Figure 1.5 is on page 9 while Figures 1.6 and 1.7 are on page 10.
2. Some terms are used before they are defined and explained. Example: on page 27 the term "cube" is used, but it isn't explained until page 61.
3. The book was written by an employee of Pentaho and focuses on the Pentaho analytics platforms. Maybe it's because I'm not particularly familiar with Mondrian so perhaps this is because I'm not familiar with the Mondrian community, but the book feels like an advertisement for Pentaho at times.
Overall a very useful book for getting all users of Mondrian (with Pentaho) up and running.
there are lots of choices out there today, from cheap and cheerful spreadsheets to full business intelligence platforms and lots in between. depending on your needs, you might be able to get by with a quick spreadsheet or an analytical software package (like python, R, etc). but unless you happen to be in a company full of highly trained data analysts (and i am not), it makes sense to have a tool that just about anyone can use.
mondrian in action is an excellent reference, with a handy quick start guide at the front for the different audiences that might be using the book. are you a business analyst? why troll through chapters outlining syntax in the middle of the book? chapters 1,2,9, and 11 are for you. application developer? chapters 1,2,8,9, and 10. it's great to not have to guess, and if you are really curious, or just can't manage to get to sleep on that flight, by all means, dig in to those other chapters.
i found the writing clear, and the examples covered most of the relevant ideas and concepts. as it seems a number of my fellow reviewers have already given a fairly complete chapter by chapter summary, i will not bore you with the same.
what i would like to have seen is a bit more information on how to use mondrian outside of the pentaho platform. i found the installation instructions in the book (and even on the mondrian website) a bit too sparse to get it up and running quickly. it took me the better part of a day and a half to get it all up and running. a 'from first principles' would have been really helpful.
