Looking for some summer holiday (or winter holiday, depending on which hemisphere you live in) reading? If so, may I suggest my new Power Query book? “Power Query for Power BI and Excel” is available now from the Apress site, Amazon.com, Amazon.co.uk and all good bookstores.
It’s an introductory level book. It covers all of the stuff you can do in the UI, it has a chapter on M, and it goes into a reasonable amount of detail on more advanced topics; it is not a 500-page exhaustive guide to the product. I’ve focused on readability and teaching the fundamentals of Power Query rather than every looking at every obscure M function, but at the same time if you’ve already used Power Query I think there’ll be plenty of material in there you’ll find interesting.
Now for the bad news: the book is out-of-date already, although not by much. One of the best things about Power Query is the monthly release cycle; unfortunately that makes writing a book on it a bit of a nightmare. I started off writing in January and had to deal with lots of added functionality and changes to the UI over the next few months; I had to retake pretty much all of the screenshots as a result. The published version of the book is based on the version of Power Query that was released in early June rather than the current version. Hopefully you can forgive this – the differences are minor – but it’s a good reason to buy the book as soon as you can! I want to do a second edition in a year’s time once (if?) the release cycle slows down.
I’ve been teased a bit for blogging and teaching so much about Power Query recently, so the final thing I want to say here is why an old corporate BI/SSAS guy like me is getting so excited about a self-service ETL tool. Well, the main reason is that Power Query is a great piece of software. It does what it does very well; it does useful things rather than what the marketing guys/analysts/journalists think is hot in BI; it is easy to use but at the same time is flexible enough for the advanced user to do really complex stuff; it is updated regularly based on feedback from its users. I only wish all Microsoft software was this good… Honestly, I wouldn’t be able to motivate myself to blog and write about Power Query if I didn’t think it was cool, and even though it hasn’t been hyped in the same way as other parts of the Power BI stack it is nonetheless the part that people get excited about when I show them Power BI. It’s not just me either – every day I see positive comments like Greg Low’s here. I think it is as important, if not more important, than Power Pivot and I think it will be a massive success.
Oh, and did I mention that I’m also teaching a Power Query course in London later this year….?
Within a matter of days, “Expert Cube Development with SSAS 2012 Multidimensional Models” will be published. It’s the second edition of the very successful (19 5* reviews on Amazon US as of now) book on SSAS cube development that Marco, Alberto and I wrote a few years ago, updated for SSAS 2012.
Before you rush off to order a copy, there are a three things I’d like to point out:
- This is basically the same book as the first edition with updated screenshots, a few bugs fixed, and several sections updated/expanded for SSAS 2012. There are no substantial changes. If you already have a copy of the first edition it’s probably not worth buying a copy of the second edition.
- The book only covers SSAS Multidimensional models, it does not cover SSAS Tabular models.
- This is not a basic introduction to building SSAS cubes – it’s aimed at intermediate-level SSAS developers who are already familiar with cubes, dimensions and MDX and who want to learn about best practices, design patterns, performance tuning and (most importantly) which features work well and which ones don’t. If you like the material I post here on my blog, you’ll probably like the book.
If you’re OK with that then by all means, go ahead and get your wallet out!
I decided to wait until I had a real, physical, made-of-dead-tree copy of it in my hands before blogging, but I’m pleased to announced that the new book that Marco, Alberto and I wrote on SSAS 2012 Tabular models is now available to purchase (even though, as Marco says here it was actually officially released a few weeks ago).
A sample chapter can be found here:
You can buy it all all good bookshops, including Amazon UK. It has two five-star reviews on Amazon already, and Javier Guillén wrote a very detailed review here. Why not buy several copies so you can share it with your colleagues, friends, significant others, children, neighbours etc? It also makes ideal beach reading if you are currently on your holidays.
You may also have noticed there’s another SSAS Tabular book out, by Teo Lachev. Teo is an author I have the utmost respect for and I’m a big fan of everything he’s written; this book lives up to the high standards of his previous work. While it’s true there’s some overlap between his book and ours, the focus of his book is broader, covering topics such as Sharepoint, whereas ours has a narrower focus and goes into much greater detail on subjects such as DAX; so (again, as Marco says) you should probably consider buying both.
I’ve just seen that my friend Tomislav Piasevoli’s new MDX book has just been published – it’s called “MDX with Microsoft SQL Server 2008 R2 Analysis Services Cookbook” and you can get it here:
I was one of the technical reviewers on the book, so I’m not even going to pretend to review it, but it’s definitely worth checking out if you’re looking to deepen your knowledge of MDX and see some worked examples.
There’s no way I could ever pretend to be an impartial reviewer of Marco Russo and Alberto Ferrari’s new book, “PowerPivot for Excel 2010: Give Your Data Meaning”. First of all, they’re good friends of mine (we wrote “Expert Cube Development with SQL Server Analysis Services 2008” together last year); and secondly, I got a freebie copy of the book. But all that aside, I do honestly think it is a really good book. Just as an example, I’ve been playing around with some DAX problems over the last few days with a view to writing a some blog posts and had been struggling to get the EARLIER function to work in the way I’d been expecting; there are only a few examples of its use on the web but I found the book had a very detailed explanation of how it works. Indeed a large part of the book is concerned with DAX and it’s probably the best resource on that subject that I’ve seen, so that’s reason enough to buy it.
It’s important to point out, though, that Marco and Alberto’s book doesn’t really go into any detail on PowerPivot for Sharepoint – there is one chapter at the end, but it’s main focus is on PowerPivot for Excel. If you want to learn more about the Sharepoint side of things I can recommend “Professional PowerPivot for Excel and Sharepoint” by Siva Harinath, Ron Pihlgren and Denny Lee (and yes, I got this book as a freebie too – it’s one of the perks of being a blogger that you get loads of free books!). There’s very little overlap between the two books – the only thing they both cover is the basic info on how to build a PowerPivot model, and that subject is so basic most people will be able to work it out for themselves – so it’s probably worth getting both if you’re serious about learning PowerPivot.
One last bit of advertising: Marco and Alberto are running a two day PowerPivot workshop in the Netherlands at the beginning of December. More details can be found here:
As you probably know, last year I co-wrote a book called “Expert Cube Development with SQL Server Analysis Services 2008” with Marco Russo and Alberto Ferrari. Although I’m sure you all already own a copy, those of you that don’t might be interested to know that as well as the sample chapter that’s available on the book’s home page, the chapter on query performance tuning is available as a two-part article here:
In fact it’s been available for quite a while, but I thought I’d post a link up because I was searching for it the other day and couldn’t find it myself…
I’m pleased to announce that, after a lot of effort and late nights, the book that Marco Russo, Alberto Ferrari and I have been working on has finally been published! It’s called “Expert Cube Development with Microsoft SQL Server 2008 Analysis Services” and, basically, it’s a book about building cubes with Analysis Services 2008. So no surprises there then…
Why should you buy this book? There are a lot of other, really good SSAS books out there on the market, but we’d like to think ours is a bit different. For a start, it’s not a book for beginners and we assume you’ve already built a few cubes and know what a cube is; that’s not to say we ignore the basics, but we don’t spend too much time on them and as a result we can get onto the more interesting problems you’ll face when building cubes. Secondly this is a book with an opinion: we tell you which features work well and which don’t, how to work around any limitations in SSAS, and what the best practices are for building cubes; we make a lot of references to using BIDS Helper and MDX Studio for example, and not just the out-of-the-box features, and we reference a lot of useful material that’s on the net in white papers and on blogs. Thirdly, it’s meant to be a book you can read from cover-to-cover rather than a reference book: it’s relatively short, it follows the lifecycle of an SSAS project, and tries to tell a story; it doesn’t cover every possible piece of functionality in exhaustive detail. It’s not the only SSAS book you’ll ever need, but if you’ve already got a beginner-level book this will be a useful addition.
Oh, and I should point out that this is a real book and not a hoax like last time…!
I’ve just been told that "MDX Solutions" has been translated into Chinese:
It’s a shame that Wiley aren’t interested in doing a third edition at the moment, but luckily not much has changed in MDX between AS2005 and AS2008 so the content is still relevant. I see there’s some competition coming in the future from "Microsoft SQL Server 2008 MDX Step-By-Step" though…
Here’s the deal: if you liked Teo Lachev’s book "Applied Microsoft Analysis Services 2005", which I did, then you’ll like "Applied Microsoft SQL Server 2008 Reporting Services". Both books share the same format and approach and are exhaustive guides to their subjects.
In case you’ve not seen one of Teo’s books before, though, what should you expect? Well, "Applied Reporting Services 2008" is 750 pages long and covers just about every aspect of Reporting Services 2008 that’s worth covering, from installation to report design to management to security to extensibility in great detail. This probably isn’t a book you’re going to sit down and read from cover to cover, but it’s a great reference guide and Teo’s prose is very clear so reading individual chapters as and when you need to is no chore. The best thing about this book, though, is the fact that on every page you can see Teo’s vast real-world experience showing through. For some reason many books on Reporting Services fall into the trap of being Books Online rewritten, never telling you the stuff you really need to know; this book on the other hand is a goldmine of information on how things really work. Let me take the chapter I can really speak from authority on – the chapter on using Reporting Services with Analysis Services. Every other SSRS book I’ve seen has been written by someone with clearly no practical experience of using SSAS and SSRS together, and parrots the usual line about ‘great integration’ and ‘easy-to-use MDX query designer’ etc. Teo on the other hand has, for the first time anywhere, put together all the tips and tricks I’ve ever seen (plus a few I haven’t) on this topic in one place – he lists the pros and cons of the built-in Analysis Services datasource and the OLEDB datasource and how to work around them, how to handle parent/child hierarchies, using extended properties, the lot.
All in all, then, a very highly recommended book; it’s ideal for both beginners and experienced developers and probably the only Reporting Services 2008 book you’ll ever need. You can read some sample chapters and see video demos on the book website here:
