Über den Autor und weitere Mitwirkende

Irina Gorbach is a senior development lead at Microsoft. She joined the Analysis Services team soon after its creation over 11 years ago. During her work at Microsoft, Irina has designed and developed many features of the Analysis Services product, and was responsible for client subsystem: OLEDB and ADOMD.Net. Irina was in the original group of architects that designed XML for Analysis specification; she worked on the architecture and design of calculation algorithms and currently is working on scalability of Analysis Services. Alexander Berger was one of the first developers to work on OLAP systems at Panorama, prior to their purchase by Microsoft. After the acquisition, Alexander led the development of Microsoft OLAP Server through all of its major releases prior to SSAS 2008. Currently, Alexander leads the Business Intelligence department for Microsoft adCenter. He is one of the architects of OLEDB for the OLAP standard and MDX language, and holds more than 30 patents in the area of multidimensional databases. Edward Melomed is one of the original members of the Microsoft SQL Server Analysis Services team. He arrived in Redmond as part of Microsoft's acquisition of Panorama Software Systems, Inc., which led to the technology that gave rise to Analysis Services 2008. He works as a program manager at Microsoft and plays a major role in the infrastructure design for the Analysis Services engine.

5.0 von 5 Sternen Unbedingt empfehlenswert 2. Mai 2010
Format:Taschenbuch
Zur Einarbeitung in den SSAS (SQL Server Analysis Services) 2008 habe ich mich erst einmal an der mitgelieferten Produktdokumentation probiert. Auch wenn es hier einiges an Beispielen und Tutorials sowie Hintergrundinformationen gibt, sind diese meiner Ansicht nach didaktisch völlig unzureichenend. Beispiele setzen etwa weiterführende Kenntnisse voraus, die Einführung hat keinen roten Phase und so weiter.

Dieses Buch ist vermutlich das überzeugenste Fachbuch zu einem Spezialthema, das ich in den letzten Jahren gelesen habe. Es ist offenkundig, dass die Autoren eine tiefe Kenntnis haben - gut, das war auch zu erwarten. Darüber hinaus ist aber auch der Aufbau des Buches didaktisch hervorragend - und das hat mal selten in Kombination: entweder weiß der Autor nicht wirklich, wovon er schreibt [die Hype-Bücher] oder ein 'Nerd / Geek' versucht, sein Baby an den Mann zu bringen. Hier bauen die Kapitel intelligent aufeinander auf, die Beispiel sind auch bei komplexen Themen einfach gehalten und setzen nur das bisher erarbeitet auf. Die Darstellung ist dabei keineswegs oberflächlich, sondern von einer angemessenen Tiefe. Selbst Detailbeschreibungen der Implementierung, die beim Verständnis der Arbeitsweise des SSAS helfen, können auch ohne weitere Vorkenntnisse aufgenommen werden. Angenehm ist auch, dass jeder missionarische Eifer der Autoren trotz ihrer engen Bindung mit dem Produkt aussen vor bleibt. Die Darstellung ist nüchtern und teilweise offen im Bereich von Schwachstellen.

Das Buch ist ein Überblick und eine Einführung mit einem sehr gut durchdachten roten Faden. Dabei werden vereinzelt auch technische Details diskutiert.

5.0 von 5 Sternen Excellent book for the internals of SSAS 9. Februar 2009
Von Craig Utley - Veröffentlicht auf Amazon.com
Format:Taschenbuch
First, this book is not a tutorial. If you don't know SSAS and want to learn it, look elsewhere first and return to this book later.

What this book provides is an in-depth view of how Analysis Services really works. For those of us who spend most of our time working with Analysis Services, this book is invaluable for understanding how the engine behaves and why. You'll find details on processing, aggregations, attribute relationships, and virtually every other aspect of SSAS. The level of detail is exactly what you would expect from members of the SSAS team at Microsoft, which is to say it is very detailed and technical in nature.

There are five chapters on MDX that explain the subtleties of the various functions and how they perform. There are also chapters that delve into performance tuning, security, and administrative tasks. I highly recommend this book to anyone already familiar with SSAS because it contains valuable information not found anywhere else.

1.0 von 5 Sternen Wait for other SSAS 2008 4. März 2009
Von Daniel T. Clark - Veröffentlicht auf Amazon.com
Format:Taschenbuch|Verifizierter Kauf
I have thousands of hours of experience with SSAS 2000 and 2005. I think that SSAS is one of the best (if unappreciated) Microsoft products.

I bought this book for one reason - it was the first one available. If you need one now, then get it. But be warned that it's not particularly good.

The key problem is that the authors are fascinated with XML. They use raw XML to explain a wide variety of concepts and tasks. For the authors and publishers, it has the benefit of wasting a lot of space. This fattens the book and makes it look like you are getting more for your money.

Unfortunately for the readers, the book is difficult to read and completely misses the point of the SSAS interface. XML is the underlying metadata structure of SSAS. That is the last place you should look to understand cube and dimensional structure, or for modifying how the cube works.

For a professional programmer (me), time is money and productivity is everything. First you should should use the graphical and tabular representation of metadata to manipulate the cubes and dimension. THEN, you write MDX functions when necessary. If all else fails, mess with the XML.

If you can wait a few weeks, there are two new books coming out for AS 2008. I believe either would a much better alternative to this book.

Don't waste your money buying this book like I did.

Regards,

Dan.

3.0 von 5 Sternen Needs an editor 9. Februar 2009
Von JNL - Veröffentlicht auf Amazon.com
Format:Taschenbuch
If this is the best SSAS book for the hardcore technologist, then I shudder to think what the worst one is.

I bought this book having no knowledge of the SSAS product or MDX. However my preference is for a theory-heavy book rather than a step-by-step introductory tutorial, so I would rather go straight for the jugular with the expert level book. To their credit the authors being deeply involved in the development of SSAS seem to know the product quite well, but their ability to explain concepts effectively and give you the big picture, enabling you to best construct an OLAP system with their product, is a bit lacking.

First, I'm puzzled how a book can go to mass production without someone at least running the text through the grammar checker--there are numerous grammatical errors throughout this book. The index also doesn't seem very accurate. I also found myself questioning the correctness of a couple code samples. These are but the first signs that the book was hastily written & published in an effort to be the first book to market on the 2008 version.

My second problem is with the ability of the authors to explain concepts of a technology that is foreign to people coming from the RDBMS mindset. MDX is an odd language, but many of their explanations & code samples often make the language even more confusing than is probably necessary. Let's take an example: in the cube-based mdx script chapter, they introduce the concept of static vs. named sets. They essentially explain it as such: "dynamic named sets are different than static named sets. Without explaining what a dynamic named set is, we'll just give you a code sample showing you the difference and hope you figure it out." While it is possible to then figure out the concept, I found myself very slowly reading the MDX chapters to try to both grasp the odd syntax of the language while understanding the subtleties of their cryptic code samples. Having gone through the MDX chapters I still don't think I know how to best use all the features of the language, and will probably only learn it by writing it.

Third, while it might not necessarily be the fault of this book, reading it makes me want to strangle whoever created MDX. Where is Anders Helsberg when you need him? This language is a mess. For example, we have a NON EMPTY operator and NonEmpty function being deceptively similar, yet different. Why not give them different names, just to make it a little less confusing? Also if the WHERE clause is so different from a SQL WHERE clause, why not call it something else? I get the feeling this language has gone through a few iterations to make it more SQL-like, and in so doing the original vision has been hijacked with "improvements" that only muddle it. My frustration with this book is it hasn't successfully enabled me to "get" the method to the madness of this language; i'm often distracted by its peculiarities.

One positive note, if you read carefully you will pick up some best practices, recommendations for optimizing performance, etc. It would've been nice to have a chapter dedicated to best practices, so if you don't have the time and need to skim, you can get the information quickly. However its there if you dig.

1.0 von 5 Sternen Totally useless if you want to get any real work done 25. März 2011
Von Eric J. Lynch - Veröffentlicht auf Amazon.com
Format:Taschenbuch
This book will not teach you what you need to do to make SSAS work for you. It will make you a PhD in what SSAS does under the hood. The author clearly hasn't used this tool in the real world, even though he is clearly smart enough to have built it. I mean, who really cares about the bit structure of how SSAS stores strings? He also spends a LOT of space showing you the DDL of the data structures you build in SSAS in XML format. Seriously? Wish I hadn't bought this book. It's totally worthless for those of us who have jobs and need to get some real work done.

To coin an analogy, if you were looking for a book on auto racing, this book won't teach you the first thing about winning races. But it'll teach you everything you ever wanted to know about the chemical make up of the metals that were used to cast your engine block. Hope this helps.

4.0 von 5 Sternen Excellent if you want/need to really get under the covers 3. März 2011
Von Animation Fan - Veröffentlicht auf Amazon.com
Format:Taschenbuch|Verifizierter Kauf
Don't get this book for any sort of introduction to Analysis Services, though it attempts to have sufficient breadth to have something for everyone. This book would be best for someone who has already worked extensively with Analysis Services for several years and wants or needs to take it to the next level, in terms of cube size and performance (both processing and querying), where you really need to understand what is going on in the engine under the covers.

Something that is rarely appreciated is just how open Microsoft has always been with respect to this product in allowing such detailed information on its inner workings to be made publicly available. The chapters on internals are the most valuable compared to other information sources that are out there.

It is true as another reviewer complained that there exist an unnecessary number of grammatical, syntax and spelling errors (the only reason I don't give 5 stars), but they are and I hate to say it, minor irritants compared to the valuable information presented. The other negative reviews I just don't grock at all. If I have any complaint it is that many of the internals details are presented so matter-of-factly that they can slide right by you without your realizing their significance or implications. They also could have included more on how the workings that are revealed relate to the many server parameters you can adjust and the many performance monitor counters you can utilize in SQL Server Profiler and perfmon to gain deep insight into what is going on underneath.

If you aren't already conversant with Profiler, get a good book on it too, like Mastering SQL Server Profiler by Brad McGehee - it's focused on SQL Server counters but it all applies to AS also. Profiler and perfmon are your friends when to comes to deep diving AS performance.

I also appreciated the chapter on coding with ADOMD.NET, a topic that many MS AS practitioners never get close to even with years of experience - it's a great quick-start.
