Re: Are Tableau and Power BI the future of Business Intelligence?

Recently, I come across a LinkedIn post regarding MS Power BI and Tableau: Here

I love both and I posted my comment:

No doubt Tableau offers the best interactive data visualization front end but is weak at data preparation. You always need to use Tableau together with at least one data preparation package such as Alteryx, which is popular in high end Tableau community. With the recent release of Tableau 9.0’s LOD calculation,it is closing the gap with traditional OLAP technology such as SQL Server Analysis Services Multi-dimensional mode. But not there yet, for example, the lacking of SCOPE assignment (cell value overriding). But I do admit, using Tableau is addictive. It is an art, not just a tool.

Power BI is different. Within Power BI stack, Microsoft Power Query has VERY strong self service data preparing (ETL) and sharing (shared query repository, a.k.a Data Catalog) capabilities. Power Pivot, on the other hand, is a very powerful true (multi-tables) data modelling engine. You can build full dimensional modelling in Power Pivot and you can scale up from desktop based Power Pivot to server based SQL Server Analysis Services Tabular cube. Combined with the next generation SQL Server 2016, it is deeply integrated into the whole Microsoft Data Platform not just BI but whole data management landscape.
