Microsoft Readies SQL Server ‘Katmai’


By David Worthington
May 9, 2007 — 
The next generation of Microsoft SQL Server, code-named Katmai, is slated for release next year. Microsoft corporate vice president Ted Kummert, of the company’s data and storage division, will divulge selected details about Katmai during his keynote address at the Business Intelligence conference in Seattle tomorrow.

Preliminary product literature reveals that Katmai will be more deeply integrated with Microsoft Office system front-end tools, including Office Excel, Excel Services, Office SharePoint Server and Office PerformancePoint Server 2007, its business score-carding application. Katmai’s reporting capabilities will be more robust, supporting any report size or complexity.

Additionally, it will manage and accept nonrelational data types, including documents, geographic information and XML. Katmai provides more advanced data warehousing capabilities with Integration Services and Change Capture Functionality, and can synchronize data from devices to the central data store.

On the flip side, Katmai enables applications to interact with local data stores and synchronizes the local store with a central store for reference and line-of-business data.

Katmai also supports the next-generation ADO.NET data access framework to define business entities, according to the literature. Data entities can be retrieved and queried natively within any .NET language—compliments of LINQ (Language Integrated Query). LINQ support is built into the upcoming Visual Studio “Orcas” release, which will reach beta 2 by the end of this year, Microsoft officials have said.

Katmai integrates with Visual Studio 2005 as well as Visual Studio Orcas and supports the .NET 3.0 Framework.

Administrative and security features have not been overlooked. Katmai has shifted SQL Server from scripts to a rules-based management framework. It defines a common set of policies for database operations that are automatically published, enforced and monitored on servers across the enterprise. The contents of entire databases may be encrypted.

Katmai collects performance data and generates management reports with historical comparisons. A resource governor defines individual resource limits and can prioritize workloads.

Microsoft literature states that database mirroring, a feature introduced in SQL Server 2005, will simplify application recovery from storage failures, and that system administrators can add system resources without affecting applications.

Private beta testing could begin as early as June, according to an Austrian TechNet blog post published in April.
