What Is The Difference Between Ssas 2005 And Ssas2008?
In 2005 its not possible to create an empty cube but in 2008 we can create an empty cube.
A new feature in Analysis Services 2008 is the Attribute Relationships tab in the Dimension Designer . to implement attribute relationship is complex in ssas 2005
we can create ONLY 2000 partitions per Measure Group in ssas 2005 and the same limit of partitions is removed in ssas 2008.
How You Provide Security To Cube?
By defining roles we provide security to cubes. Using roles we can restrict users from accessing restricted data.
Procedure as follows
Define Role
Set Permission
Add appropriate Users to the role
