  • 2.  Power View enables self-service BI by providing simple to use ad-hoc reporting for business users and decision makers.  Power View provides an interactive data exploration, visualization, and presentation experience.  Power View is a browser-based Silverlight application which can be launched from SharePoint 2010.  Users can create rich visualizations and interact with data from BISM models including:  SSAS Tabular models deployed to SSAS instance in Tabular mode available in SQL Server 2012 RTM.  PowerPivot workbooks deployed to Sharepoint 2010 PowerPivot Gallery.  SSAS Tabular models and PowerPivot are based upon the VertiPaq engine (in- memory analytics engine), which is now renamed to xVelocity as of March 9, 2012.  SSAS Molap engine in future, based upon conversation with SSRS product manager.
  • 3.  Always presentation ready  Export Power View report to PowerPoint and interact with it through that interface.  Based on Tabular models  Visual design experience  Similar MS Office ribbon.  Easy data switching between visualizations at all times. No design vs. run-time.  When creating data visualizations always start with a table then switch between different available visualizations such matrices , bubble charts, bar and line graphs, and even small set of multiple charts.  Easy filtering and highlighting of data because Power View knows the relationships between the data based upon the underlying metadata.  Easy sorting of tables, matrices, bar and column charts, and small sets of data either ascending or descending on attributes or measures.  Performance  Power View retrieves rows needed for the data visualization. Even if the underlying table contains millions of rows, Power View only fetches rows needed for the visualization at the time.  Queries  Power View runs DAX queries against the Tabular models.
  • 4.  SQL Server 2012 RTM – SSRS feature available in Enterprise (Developer also) and Business Intelligence versions.  Also, SSAS Tabular and PowerPivot for SharePoint are only available in Enterprise and BI versions.  Web browsers support includes IE 7,8,9, Firefox7, and Safari 5.  SharePoint 2010 Enterprise edition is required with SP1 recommended. Reporting Services Add-On for SharePoint products is added from the SQL Server 2012 onto SharePoint server.  Microsoft Silverligh 5.  If using SSAS Tabular engine, multiple hops, and need to secure the data at the cell level then Kerberos authentication will have to configured.  Installation checklist available on MSDN which provides details on installation and configuration of SQL Server 2012 BI features with Sharepoint. 
  • 5.  Pull data from the source systems into either PowerPivot or SSAS Tabular models.  Define relationships between the data in the tables. Author any DMX formulas for calculations.  Publish the PowerPivot workbook to SharePoint or deploy the SSAS Tabular model to the server.  Power View visualizations can be built using a tabular model connection in any of the following three ways:  PowerPivot for SharePoint workbook published in a PowerPivot Library view (Gallery, Theater, or Carousel) in SharePoint.  BISM report server data source (.rsds) type published in a SharePoint Report Library that connects to a database running on SQL Server 2012 SSAS Tabular mode server.  BISM Connection file (.bism) published in a SharePoint Report Library which can connect to any of the following:  Database running on SQL Server 2012 SSAS Tabular mode (Windows authentication only).  PowerPivot for SharePoint workbook.
