Analysis Services includes the following improvements to designing aggregations:

• New Aggregation designer. A new Aggregation designer makes it easier to browse and modify aggregation designs. Aggregation designs are now shown grouped by measure group. A new view for manual aggregation design is now available for advanced users.
  
• Simplified and enhanced Aggregation Design and Usage-Based Optimization Wizards. These updated wizards let you modify the storage settings for aggregations in one or more partitions at a time and more easily set aggregation usage settings. The Usage-Based Optimization Wizard now also lets you append new aggregations to an existing aggregation.
  
• New AMO Warnings. These new warning messages alert users when they depart from aggregation design best practices.
  

The cube wizard has been simplified and enhanced. The improvements help you create better cubes in fewer steps.

Analysis Services includes the following improvements to designing dimensions:

• New Attribute Relationship designer. The dimension editor has a new Attribute Relationship designer that makes it easier to browse and modify attribute relationships.
  
• New AMO Warnings. These new warning messages alert users when they depart from design best practices or make logical errors in database design.
  
• Simplified and enhanced Dimension Wizard. This latest version of the wizard auto-detects parent-child hierarchies, provides safer default error configuration, and supports specification of member properties.
  
• New Key Columns dialog box. This new dialog box makes editing key columns easier.
  
• Key column support in the Properties Panel. Key columns can now be edited in the Properties panel.
  
• Updated Dimension Structure tab. This tab now works with the new Attribute Relationship designer and is simpler to use, which makes modifying attributes and hierarchies easier.
  

The backup and restore functionality in Analysis Services has a new storage structure and enhanced performance in all backup and restore scenarios.

Analysis Services personalization extensions enable developers to create new Analysis Services objects and functionality and to provide these objects and functionality dynamically in the context of the user session. Developers do not have to create detailed specifications about where or how to find the extended functionality. Instead, developers can share these new objects and functionality immediately with both end users and other developers.

For a sample that illustrates how to create user-based personalizations, see Readme_Analysis Services Personalization Extensions Sample.

Books Online no longer includes SQL Server sample databases and sample applications. These sample databases and sample applications are now available on the SQL Server Samples Web site. This Web site makes it easier for users to find these samples, and provides additional new samples that are related to Microsoft SQL Server and Business Intelligence. On the SQL Server Samples Web site, you can do the following:

• Browse through samples contributed by developers, users, and the Microsoft Most Valuable Professional (MVP) community.
  
• Download both sample databases and code projects.
  
• View or participate in a discussion area where you can report issues and ask questions about the samples for each technology area.
