Store any information




DATE/TIME

SQL Server 2008 introduces new date and time data types:




DATE€”A date-only type


TIME€”A time-only type


DATETIMEOFFSET€”A time-zone-aware datetime type


DATETIME2€”A datetime type with larger fractional seconds and year range than the existing DATETIME type

The new data types enable applications to have separate data and time types while providing large data ranges or user defined precision for time values.

HIERARCHY ID

Enable database applications to model tree structures in a more efficient way than currently possible. New system type HierarchyId can store values that represent nodes in a hierarchy tree. This new type will be implemented as a CLR UDT, and will expose several efficient and useful built-in methods for creating and operating on hierarchy nodes with a flexible programming model.

FILESTREAM Data

Allow large binary data to be stored directly in an NTFS file system, while preserving an integral part of the database and maintaining transactional consistency. Enable the scale-out of large binary data traditionally managed by the database to be stored outside the database on more cost-effective storage without compromise.

Integrated Full Text Search

Integrated Full Text Search makes the transition between Text Search and relational data seamless, while enabling users to use the Text Indexes to perform high-speed text searches on large text columns.

Sparse Columns

NULL data consumes no physical space, providing a highly efficient way of managing empty data in a database. For example, Sparse Columns allows object models that typically have numerous null values to be stored in a SQL Server 2005 database without experiencing large space costs.

Large User-Defined Types

SQL Server 2008 eliminates the 8-KB limit for User-Defined Types (UDTs), allowing users to dramatically expand the size of their UDTs.

Spatial Data Types

Build spatial capabilities into your applications by using the support for spatial data.




Implement Round Earth solutions with the geography data type. Use latitude and longitude coordinates to define areas on the Earth's surface.

Backup Compression

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.

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.

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

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.

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.

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.

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.

SQL Server Integration Services (SSIS) Persistent Lookups
