Just like any other major release of SQL Server there new features available in the Enterprise Edition of the product. With the release of SQL Server 2012 this is no different. The big difference with the release of SQL Server 2012 is the removal of the DataCentre Edition from the suite of available editions, and the inclusion of the new Business Intelligence Edition into the suite.
A quick breakdown of the 3 main editions available:
|For Mission Critical & Applications Data Warehousing||For Premium Self-Service and Corporate Business Intelligence||Continues to offer basic database, reporting and analytics capabilities|
A comparison of the features available between the 3 editions is available at SQL Server 2012 Capabilities.
A Licensing overview of the 3 editions is available at SQL Server 2012 Licensing Overview. Have a read of my previous Blog post SQL Server 2012 Licensing – How does it compare to get an idea of changes in the licensing.
