We had the SQL Server 2012 release some time ago and usually after such a release many books get released. During the summer I had the opportunity to read the first of many to come :). I stated with Marco, Chris and Alberto’s book on the tabular model. I would recommend this book for anyone who wants to know what the tabular model is all about, don’t know if to start with Tabular or keep with multidimension or has already decided to go Tabular. The book covers the background of Tabular, how you should model the data, optimize the model and write DAX.
Although I haven’t read this one myself, I do have it in my possession and will read it soon, Applied Microsoft SQL Server 2012 Analysis Services: Tabular Modeling by Teo Lachev. His previous book was great and that alone warrants reading this book, It promises a great overview of the MS BI stack as of SQL Server 2012. It is great if are a consultant and need to sell or implement the entire MS BI stack. It covers PowerPivot, tabular model and SharePoint integration (including Power View).
Of course with SQL 2012 came Power View and that warrants a book just for that, luckily that is available for you: Visualizing Data with Microsoft Power View
Another great book that will be here soon is the “Professional Microsoft SQL Server 2012 Analysis Services with MDX and DAX ” written by my colleagues Denny Lee, Siva Harinath, Ron Pihlgren, Robert Bruckner and John Sirmon. This book is a whopping 1176 pages and covers all that is new in SQL Server 2012 from the Anlayisis services team and how this integrates into SharePoint and Power View. The book goes in depth in many parts of the the product. This book is great is you want to know all there is to know about the product :).
