In SQL Server 2012 Microsoft introduced the BI Semantic Model - "BISM". BISM encompasses the different deployment options for Business Intelligence within SQL Server 2012. The highest level choice is between Multi-dimensional Analysis Services and Tabular. Multi-dimensional is the latest incarnation of the hierarchical Analysis Services model which has been in widespread use since SQL Server 2000, and was heavily revised in SQL 2005 and 2008. Tabular is a new deployment option specific to SQL 2012 and based around tables rather than hierarchies.
+
SQL Server 2012 Tabular models can be deployed either in-memory to the xVelocity engine, or using Direct Query mode. Any MDX client tool can access Tabular models deployed to xVelocity. If the model is deployed using Direct Query mode, they can only be queried through DAX, and not MDX. FluenceXL version 7 can use both MDX and DAX, and so can access any of the BI deployment modes available in SQL 2012. The diagram below outlines this.
  
MDX is the query language of hierarchical cubes, and continues to be used to query SQL 2012 Multi-dimensional. It can also be used to query Tabular models which have been deployed to the xVelocity (previously vertipaq) in-memory engine within Analysis Services. So Tabular models which have been deployed this way can be queried by any MDX generating client tool (by and large anything which could connect to Analysis Services previously), or also through the DAX language.

Tabular models can also be deployed using Direct Query mode, but these can only be queried through DAX, and not MDX. In terms of the native client tools for SQL 2012, Pivot Tables use MDX, and PowerView uses DAX. To connect to all the BISM deployment modes you would need both Pivot Tables and Powerview. XLCubed felt users would benefit from a consistent experience whichever flavour of BISM was being accessed, and so version 7 can query using MDX or DAX (with the new table object).

Introduction

SQL Server 2012 Tabular models can be deployed either in-memory to the xVelocity engine, or using Direct Query mode. Any MDX client tool can access Tabular models deployed to xVelocity. If the model is deployed using Direct Query mode, they can only be queried through DAX, and not MDX. FluenceXL version 7 can use both MDX and DAX, and so can access any of the BI deployment modes available in SQL 2012. The diagram below outlines this.

The new Table object in FluenceXL can connect to Analysis Services cubes (MDX), Tabular Models (DAX), or relational SQL (SQL). The DAX tables provide access to all Tabular models in SQL 2012.

Grids

Grids can be used against In-Memory cubes, and all the standard FluenceXL functionality can be accessed.

See the normal Analysis Services pages for information on how to use these features, they function consistently with Multidimensional cubes.


Tables

Tables provide a simple way of querying a tabular model. All of the standard functionality provided by FluenceXL tables can be used.

Insert a table by going to the FluenceXL ribbon and selecting Insert Data Table -> Analysis Services Tabular

This will allow you to select a connection to a Tabular cube, and bring up the report designer.

Slicers

Slicers give users simple to use pick lists which can be used to filter reports.

By adding a slicer based on Tabular Analysis Services you create a slicer that can be linked directly to a Table.

As with standard cube slicers, you can restrict the members shown to those with data by putting a measure into the Filters section.

The following slicer gives all the years for which there is Sales data.

Hierarchies

As of Version 7.6 FluenceXL supports tabular hierarchies, provided the server is on SSAS2012 SP1 or above.

Hierarchies can be used in two ways:

  • Placed on the Filter area - you get a treeview to select the report filter.
    • This can also be linked to a treeview slicer if required.
  • Placed on the Selected Columns area - you can drill into the data by double clicking a value, and drill back up by double clicking the column header.


Calculations

You can create new DAX calculations for your report without updating the cube.

These calculations are stored with the workbook, and are available from any grid, table or formula in the book.

Access the wizard through the Custom Calculations ribbon item. Click the DAX button (highlighted) to create a new calculation, and then use the controls on the right to select

  • Table the measure will appear in
  • Name for the measure
  • Formula to define the measure

You can drag tables, columns and measures from the tree on the left into the formula area to insert their names.
