SQL Server 2008 New Features
SQL Server 2008 provides a comprehensive platform, delivering intelligence where your users want it.
3.1、Integrate any data
Keeping disk-based backups online is expensive and time-consuming. With SQL Server 2008 backup compression, less storage is required to keep backups online, and backups run significantly faster since less disk I/O is required.
3.1.2、Partitioned Table Parallelism
Partitions enable organizations to manage large growing tables more effectively by transparently breaking them into manageable blocks of data. SQL Server 2008 builds on the advances of partitioning in SQL Server 2005 by improving the performance on large partitioned tables.
3.1.3、Star Join Query Optimizations
SQL Server 2008 provides improved query performance for common data warehouse scenarios. Star Join Query optimizations reduce query response time by recognizing data warehouse join patterns.
Grouping Sets is an extension to the GROUP BY clause that lets users define multiple groupings in the same query. Grouping Sets produces a single result set that is equivalent to a UNION ALL of differently grouped rows, making aggregation querying and reporting easier and faster.
3.1.5、Change Data Capture
With Change Data Capture, changes are captured and placed in change tables. It captures complete content of changes, maintains cross-table consistency, and even works across schema changes. This enables organizations to integrate the latest information into the data warehouse.
3.1.6、MERGE SQL Statement
With the introduction of the MERGE SQL Statement, developers can more effectively handle common data warehousing scenarios, like checking whether a row exists, and then executing an insert or update.
3.1.7、SQL Server Integration Services (SSIS) Pipeline Improvements
Data Integration packages can now scale more effectively, making use of available resources and managing the largest enterprise-scale workloads. The new design improves the scalability of runtime into multiple processors.
3.1.8、SQL Server Integration Services (SSIS) Persistent Lookups
The need to perform lookups is one of the most common ETL operations. This is especially prevalent in data warehousing, where fact records need to use lookups to transform business keys to their corresponding surrogates. SSIS increases the performance of lookups to support the largest tables.
3.2、Deliver relevant information
3.2.1、Analysis Scale and Performance
SQL Server 2008 drives broader analysis with enhanced analytical capabilities and with more complex computations and aggregations. New cube design tools help users streamline the development of the analysis infrastructure enabling them to build solutions for optimized performance.
Block Computations provides a significant improvement in processing performance enabling users to increase the depth of their hierarchies and complexity of the computations.
New MOLAP enabled writeback capabilities in SQL Server 2008 Analysis Services removes the need to query ROLAP partitions. This provides users with enhanced writeback scenarios from within analytical applications without sacrificing the traditional OLAP performance.
3.3、Drive actionable insights
3.3.1、Enterprise Reporting Engine
Reports can easily be delivered throughout the organization, both internally and externally, with simplified deployment and configuration. This enables users to easily create and share reports of any size and complexity.
3.3.2、Internet Report Deployment
Customers and suppliers can effortlessly be reached by deploying reports over the Internet.
3.3.3、Manage Reporting Infrastructure
Increase supportability and the ability to control server behavior with memory management, infrastructure consolidation, and easier configuration through a centralized store and API for all configuration settings.
3.3.4、Report Builder Enhancements
Easily build ad-hoc and author reports with any structure through Report Designer.
3.3.5、Built-In Forms Authentication
Built-in forms authentication enables users to easily switch between Windows and Forms.
3.3.6、Report Server Application Embedding
Report Server application embedding enables the URLs in reports and subscriptions to point back to front-end applications.
3.3.7、Microsoft Office Integration
SQL Server 2008 provides new Word rendering that enables users to consume reports directly from within Microsoft Office Word. In addition, the existing Excel renderer has been greatly enhanced to accommodate the support of features, like nested data regions, sub-reports, as well as merged cell improvements. This lets users maintain layout fidelity and improves the overall consumption of reports from Microsoft Office applications.
SQL Server Analysis Services continues to deliver advanced data mining technologies. Better Time Series support extends forecasting capabilities. Enhanced Mining Structures deliver more flexibility to perform focused analysis through filtering as well as to deliver complete information in reports beyond the scope of the mining model. New cross-validation enables confirmation of both accuracy and stability for results that you can trust. Furthermore, the new features delivered with SQL Server 2008 Data Mining Add-ins for Office 2007 empower every user in the organization with even more actionable insight at the desktop.
