The November CTP of SQL Server 2008 is a huge step forward as we continue delivering on our Data Platform Vision for “Your Data, Any Place, Any Time.” SQL Server 2008 will bring that vision to life, and there is something in this feature-rich CTP to meet the needs of companies of all sizes. I really believe it is going to be an eye opener for a lot of people, not just in terms of the new features that will be included, but how close we are to delivering a final product with very high quality. Here a just some of the great new/improved features.
Data Collection and Performance Warehouse for Relational EnginePerformance tuning and troubleshooting are time-consuming tasks for the administrator. To provide actionable performance insights to administrators, SQL Server 2008 delivers more extensive performance data collection, a new centralized data repository for storing performance data and new tools for reporting and monitoring.
Service Broker Enhancements Getting the data to the right place at the right time is important. Service Broker Conversation Priority in SQL Server 2008 gives you greater control over the system by making it easy to configure priority rules so that the most important data is sent first and processed first.
Registered Servers EnhancementsEnhancements to the Registered Servers tool window in Management Studio include running T-SQL queries and policies against groups of servers and the ability to share a common, centrally stored, server topology (Database Engine only).
Synchronous net-changes change tracking for SQL ServerSQL Change Tracking feature provides the functionality to synchronously track changes to data in user table without the need to create triggers or modify schema of the table. Applications will be able to reliably determine what data has changed since a watermark/baseline and will be able to obtain the latest data. The feature is geared towards providing the functionality with least DML overhead.
T-SQL IntelliSenseTransact-SQL IntelliSense provides intelligent aids for Transact SQL scripting that make language references easily accessible for database developers. When coding, you do not need to leave the Database Query Editor to perform searches on T-SQL language elements or your database metadata. You can keep your context, find the information you need, insert T-SQL language elements directly into your code, and even have IntelliSense complete your typing for you. This can speed up software development by reducing the amount of keyboard input required and minimize references to external documentation.
Declarative Management Framework (DMF) EnhancementsEnhancements to DMF include more expressive conditions (including support for common functions, T-SQL, and WMI queries), more robust target set filtering, custom messages for policies, and the inclusion of best practice policies.
Geo-spatial SupportSQL Server 2008 delivers comprehensive geo-spatial support. The new GEOGRAPHY and GEOMETRY data types provide spatial data support for location-aware applications. These types can be used to store locations, as well as paths and regions in space, and provide a rich set of functionality for comparing and manipulating these objects. Use the GEOGRAPHY type when working with latitude and longitude coordinates in a true round-earth model; use GEOMETRY when working in projected planar surfaces, as well as naturally planar systems such as interior spaces. These types are supported by new spatial indexes, which provide for fast execution of queries involving spatial data. The query optimizer has been enhanced to build-in knowledge of spatial indexes and types, so that appropriate cost-based plan decisions can be made.
Analysis Services Query and Writeback Performance (FITS)New MOLAP-enabled write-back capabilities in SQL Server 2008 Analysis Services remove the need to query ROLAP partitions. This provides users with enhanced writeback scenarios from within analytical applications without sacrificing the traditional OLAP performance.
Robust Report Server PlatformReports can easily be delivered throughout the organization with simplified deployment and configuration. This enables users to easily create and share reports of any size and complexity.
Integration Services - Lookup EnhancementsThe need to perform lookups is one of the most common extraction, transformation, and loading (ETL) operations. This is especially prevalent in data warehousing where fact records must use lookups to transform business keys to their corresponding surrogates. SSIS increases the performance of lookups to support the largest tables.
Analysis Services MDX Query Optimizer - Block ComputationBlock computations provide a significant improvement in processing performance, enabling users to increase the depth of their hierarchies and complexity of the computations.
Analysis Services Aggregation DesignSQL Server 2008 drives broader analysis with enhanced analytical capabilities and with more complex computations and aggregations. The AS Aggregation Design improvement exposes Aggregation Design objects in SQL Server BI Dev Studio and SQL Server Management Studio and provides tools for users to better work with these aggregation designs. In addition, an advanced view in the new Aggregation Design tab of the cube editor provides the ability for an advanced user to view and manually edit individual aggregations within an aggregation design.
Analysis Services Cube DesignNew cube design tools help users streamline the development of the analysis infrastructure, enabling them to build solutions for optimized performance. The AS Cube Design improvement introduces a new Cube Wizard which helps users create better cubes in fewer steps. The new wizard focuses on having the user answer a few questions to create leaner cubes that better targets their needs. It also unblocks the previously difficult scenarios of creating a cube a cube based on a single, de-normalized table and creating a cube containing only linked dimensions.
Reporting Services Scale Engine and Robust Server Fit and FinishA reengineered memory management and scalability infrastructure lays a solid foundation of scalability capability to enterprise customers.
