It is always interesting to read the different reports which cover the BI space which is growing at a enormous space with vendors coming with different capabilities and covering different aspects plus the Cloud Based Offerings. Here is a link to the Gartner report which discusses the BI quadrant for 2013. Some quotes from this report:
Microsoft leads in ability to execute
As I did with the DW report, I'll start with the "winners" in this MQ. Each axis ("ability to execute" and "completeness of vision") had its own winner, and that for the former is Microsoft. I tend to go out of my way to point out my bias on Microsoft. I've long thought the MS BI stack provided significant value, and have watched that value increase recently with the introduction of PowerPivot and SQL Server Analysis Services Tabular mode (in-memory column store databases that are highly integrated with Excel and SharePoint) and Power View (interactive visualization technology integrated with those same products). Microsoft has also recently added Master Data Management and Data Quality tools that, while still maturing, round out very nicely a stack that costs little to nothing for customers already using SQL Server, Office and SharePoint.
