SQL Server 2008 CTP Giugno 2007

Oggi Microsoft presenta la prima CTP pubblica di SQL Server 2008 (noto in precedenza con il nome in codice "Katmai").
Vi riporto per filo e per segno l'intervento di Ed Lehman sul newsgroup privato MVP di SQL Server.

Among the 27 improvements included in the CTP are:

 Declarative Management Framework (DMF) is a new policy-based management framework for the SQL Server Database Engine that delivers the following benefits:
• Ensure compliance with policies for system configuration
• Prevent/monitor changes to the system by authoring policies for the desired configuration
• Reduce total cost of ownership by simplifying administration tasks

 Change Data Capture (CDC)
• Change Data Capture (CDC) is a generic component that will track database changes asynchronously and expose the changes through a elational interface which can be consumed easily.
• Through this interface, consumers can very easily track changes based on their specific requirements and consume the change data using T-SQL or other data access methods.

 MERGE SQL Statement
• Common data warehouse scenarios require developers to either insert information or update information. SQL Server 2008 will provide new statements within the SQL language to enable developers to provide this functionality with a single statement.

 Star Join Query Optimizations
• For improved query performance for common data warehouse scenarios, Star Join Query optimizations reduce query response time by recognizing data warehouse join patterns.

 AS Dimension Design: Improved Supportability and Integration of Best Practices
• Enhance UI for creating and editing dimensions to guide users toward designs that follow best practices.
• These include: Finish Attribute Relationship Designer, Dimension structure (presentation of attribute relationships), modification to wizards to align output with best practices, simplifying creation of composite keys, and AMO warnings (spanning all objects, not just dimensions).

 Table Value Parameters
• In many customer scenarios, it is necessary to pass a set of table structured values (rows) to a stored procedure/function on the server. These values may be used for populating/updating a table directly or for more complex manipulation of data for business logic purpose. Table valued parameter will provide an easier way to define a table type as well as allow applications to create, populate and pass table structured parameters to stored procedures and functions.

Another important accomplishment is taking the first steps for the new setup architecture with the enablement of side-by-side installations with Yukon SP2.

Along with the release of the first Katmai CTP,  we're implementing a new approach for SQL Server Samples and Community projects on Codeplex (http://www.codeplex.com/SqlServerSamples), Microsoft's open source project hosting site. Customers will now have direct access to all Microsoft SQL Server product sample source code without the need to install anything. Addressing a long-standing customer ask, customers can also install samples for specific SQL technologies from Codeplex rather having to use a single monolithic install of all samples. Microsoft SQL Server Product Samples released on Codeplex will be aligned to and tested with specific releases.

We have also started to release Community sample projects on Codeplex, which include groups of samples contributed outside of our regular product release cycle by SQL Server MVPs, Microsoft employees, or other members of the community.

The Codeplex SQL Portal page serves as a common entry point for these and other SQL Server-related projects on Codeplex. The Katmai version of SQL Server Management Studio and BI Dev Studio include a "Samples and Community Projects" link on the Community Menu that will redirect customers to the portal page.

With this approach to samples and community projects, we bring together a much broader body of code for our customers from a wide variety of sources. This new approach also enables us to take much more of a cross-product approach aligned to customer needs than the single-product focused approach we have taken in the past.

Along with the June CTP, we will be opening New MSDN Forums dedicated to Katmai located at http://forums.microsoft.com/MSDN/default.aspx?ForumGroupID=428&SiteID=1.
