Microsoft demonstrated PowerView on top of the Multidimensional model in Analysis Services several weeks ago at SQL PASS and now the CTP version of the product is available here. There are two pieces of new functionality delivered with this CTP: Update for Analysis Services engine to allow DAX support for Multidimensional models Update for the
and the Germans are making the first move… I have written two posts about Hana vs. xVelocity (Part I and Part II) making the basic point that there is nothing truly visionary or revolutionary in SAP Hana from the technology perspective and that a customer can get all the benefits (or rather alleged benefits as
Microsoft is expected to make a number of very important announcements at the upcoming SQL Pass conference in Seattle… If you are on the fence about attending it this year, I would definitely recommend attending this event.
It seems that Analysis Services supported actions for Tabular mode for a while, but who wants to maintain it using XMLA? Luckily, the BIDS Helper is more than capable. Please follow this link for additional information. This is really exciting! It is almost strange that this feature is not available in the SQL Server Data Tools
There are several UI gotchas related to building PowerView visualizations that I wanted to address with this post. First, PowerView is not available in the Ribbon out of the box, in order to enable it, one needs to go to File->Options->Add-ins.

Here is a great article on how to implement row level security for a tabular Analysis Services model. Along with security it also makes some interesting points about Parent Child relationship, that are not very friendly for the Tabular mode just quite yet.
Not surprisingly, my original post generated huge traffic to my blog as well as a couple of good comments. I am sorry that it took me a while to respond, but now that it is Saturday and I am at Starbucks,I don’t really have any excuse not to respond anymore… Before I jump into a
The second iteration of the tabular model for analysis services now allows us to implement very sophisticated security scenarios including row-level dynamic security. In order to implement it, first we need the means of finding out the windows credentials of the user. That can be accomplished using the DAX function USERNAME(). Second, we need to map
Many great discussions are taking place about the future of the Multidimensional mode for the Analysis Services. It is very clear where the majority of the investment went for the 2012 version (hint… think rows and columns and not multidimensional). At the same time, one might argue that the traditional or Multidimensional set of features is already
Microsoft recently published a Using DirectQuery in the Tabular BI Semantic Model white paper. The white paper provides a great introduction for the DirectQuery technology, xVelocity and columnstore indexes. It also covers security, capacity planning and deployment best practices.
