This dense hour of presentation will cover design techniques to leverage cube features that also consider possible maintenance of the database structure over time.
Introduce the features of BISM (BI Semantic Model), the new engine that will be available in Analysis Services "Denali".
In this session we will introduce the new modeling capabilities of Vertipaq, showing how the same scenarios can be modeled in both Multidimensional (MOLAP) and Tabular (Vertipaq), looking at how to enable your data warehouse to support both.
In this session you will see how to create a BISM Tabular data model from scratch, providing the required metadata in order to improve user experience navigating the data model by using client tools like Excel PivotTable and Power View.
This session will discuss what a modern strategy for data warehousing can be in this era, considering how the use of technologies like PowerPivot or Analysis Services Tabular affect the way you should model your data.
Learn ready-to-use DAX patterns improving development speed of Power Pivot solutions. Good also for SSAS Tabular developers.
Explore Power Query features to import data from existing Corporate BI systems.

Using decimal numbers in Power Pivot and Tabular might produce small rounding differences in certain calculations. This is nothing new when you work with floating point, as many programmer knows. The implementation of RANKX might suffer of a behavior producing wrong results when the measures used ...

During the last months I’ve seen an increasing adoption of Analysis Services Tabular (and I’m writing a longer article about a particular area of adoption which was probably not expected – more on that in a few weeks). This year at PASS Summit 2014 there are plenty of opportunities to learn (or ...

Alberto published the Rolling 12 Months Average in DAX article on SQLBI a few days ago, which includes interesting consideration about how to avoid the pitfall of touching the boundaries of the Date table, which could result in a calculation error. More interesting for the geek of us is the ...
