My first thoughts when I heard about the Datazen acquisition were…How is it different? When do I choose to use it? What are its strengths? I summarized some high level use cases in this blog entry I published on the BlueGranite site. In this post I would like to go through some detailed comparisons between Datazen, Reporting Services, and Power View. Note that I’ve chosen to focus on Power View rather than Power BI as a whole because Power View is the primary visualization component within Power BI (whereas Power Query and Power Pivot are more about data shaping and data modeling which isn’t as directly relevant when compared to Datazen and Reporting Services). For brevity I’ve omitted Excel and Performance Point from the comparison as well. Also, Power BI for Office 365 is *not* addressed here since it’s being phased out for Power BI v2 – any Power BI references here refer to the Power BI Preview also commonly known as v2.
References below are applicable to:
-Datazen Version 3.0
-Reporting Services in SQL Server 2014
-Power View for Excel 2013
-Power View for SharePoint 2013
-Power View in Power BI (v2)
This analysis is as of mid-June 2015, and will certainly evolve and change as Datazen becomes more integrated in the Microsoft ecosystem, as Power BI evolves, and with SQL Server 2016 coming out soon.

Yes (needs a join key in some cases) |
Yes (one data source per dataset is general rule, though a tablix expression can reference another dataset and/or lookups can be utilized) |

Yes (In V2, datasets published to the Power BI service are independent objects from reports and dashboards |
|
Shared report elements (i.e., reusable charts and tables across multiple reports / dashboards) |
Report elements: Not shareable across multiple master views or multiple dashboards (tablet and phone views utilize some or all elements from a single master view)
KPIs: KPIs are independent of dashboard elements; a KPI can drill to a related dashboard |
Yes (report parts which are elements such as tables, charts, gauges, images, maps, parameters, etc. published for reuse) |
Yes (Power BI v2 portal supports the ability to ‘pin’ a report element onto one or more dashboards after the report has been published to the Power BI site) |
|

No |
|
Snapshot reporting |
No |
Yes (report execution snapshot to improve performance, or report history snapshot to store report as of a point in time) |

|
Pinning of report elements |
KPIs can be pinned to Windows 8 start page as a live tile
Dashboards can be pinned to Windows 8 start page as a shortcut to open dashboard |
No |
