SQL Server 2008 Features What’s New in SQL Server 2008 Transparent Data Encryption External Key Management Enhanced Auditing SQL Server 2008 enables encryption of entire databases, data files, and log files, without the need for application changes. Encryption enables organizations to meet the demands of regulatory compliance and overall concern for data privacy. Some of the benefits of transparent data encryption include searching encrypted data using either range or fuzzy searches, more secure data from unauthorized users, and data encryption. These can be enabled without changing existing applications. SQL Server 2008 provides a comprehensive solution for encryption and key management. To meet the growing need for greater security of information within data centers, organizations have invested in vendors to manage security keys within the enterprise. SQL Server 2008 provides excellent support for this need by supporting third-party key management and hardware security module (HSM) products. SQL Server 2008 improves compliance and security by allowing you to audit activity on your data. Auditing can include information about when data has been read, in addition to any data modifications. SQL Server 2008 has features such as enhanced configuration and management of audits in the server, which enable organizations to meet varied compliance needs.

SQL Server 2008 Features What’s New in SQL Server 2008 File Stream Data Geographical Information The new SQL Server 2008 FILESTREAM data type allows large binary data like documents and images to be stored directly in an NTFS file system; the document or image remains an integral part of the database and maintains transactional consistency. FILESTREAM enables the storage of large binary data, traditionally managed by the database, to be stored outside the database as individual files that can be accessed using an NTFS streaming API. Using NTFS streaming APIs allows efficient performance of common file operations while providing all of the rich database services, including security and backup. GEOGRAPHY Data Type - to store planar spatial data GEOMETRY Data Type - to store geodetic spatial data

SQL Server 2008 Features What’s New in SQL Server 2008 GROUPING SETS GROUPING SETS is an extension to the GROUP BY clause that enables users to define multiple groupings in the same query. GROUPING SETS produce a single result set that is equivalent to a UNION ALL of differently grouped rows, making aggregation querying and reporting easier and faster. Example: SELECT Order_Year As Year, Order_Quarter As Quarter, Count(*) As Orders FROM Order_Details WHERE Order_Year IN (2003,2004) GROUP BY GROUPING SETS ( (Order_Year, Order_Quarter), (Order_Year) ) ORDER BY Order_Year, Order_Quarter

SQL Server 2008 Features Enhanced Database Mirroring Automatic Page Repair . SQL Server 2008 enables the principal and mirror computers to transparently recover from 823 and 824 errors on data pages by requesting a fresh copy of the corrupted page from the mirroring partner. Improved Performance. SQL Server 2008 compresses the outgoing log stream in order to minimize the network bandwidth required by database mirroring. Backup Compression . Keeping disk-based backups online is expensive and time consuming. With SQL Server 2008 backup compression, less I/O is required, less storage is required to keep backups online, and backups run significantly faster. Data Compression. Improved data compression enables data to be stored more effectively and reduces the storage requirements for your data. Data compression also provides significant performance improvements for large input/output-bound workloads such as data warehousing.

SQL Server 2008 Features Transact-SQL Improvements Table Value Parameters – In many scenarios, it is necessary to pass a set of table-structured values (rows) to a Stored Procedure or Function on the server. These values may be used for directly populating or updating a table or for more complex manipulation of data. TVP provide an easier way to define a table type and to allow applications to create, populate, and pass table-structured parameters to stored procedure and functions. Object Dependencies – The Object dependencies improvement provides reliable discovery of dependencies among objects through newly introduced catalog view and dynamic management functions. Dependency information is always up-to-date for both schema-bound and non-schema-bound objects. Dependencies are tracked for stored procedures, tables, views, functions, triggers, user-defined types, XML schema collections, and more Date & Time Data Types DATE – a date only type TIME – a time only type DATETIMEOFFSET – a time zone aware date/time type DATETIME2 – a date/time type with larger fractional seconds and year range than the existing DATETIME Type.
