MS SQL Server 2008 CTP July
2005에서 얼마나 더 바뀐건지는 아직 자세히 보지 않았지만 BI를 향상시키는 방향으로 기능과 기술이 추가되어있지 않을까 생각한다.
SQL Server 2008 Improvement Pillars
 |
| With SQL Server 2008 July CTP release, customers can understand and get hands-on experience with the new capabilities that, with the release of SQL Server 2008, will help them support their mission-critical platform and enable pervasive insight across the enterprise. SQL Server 2008 lays the groundwork for innovative policy-based management that enables administrators to reduce their time spent on maintenance tasks. SQL Server 2008 provides enhancements in the SQL Server BI platform by enabling customers to provide up-to-date information with Change Data Capture and MERGE features, and develop highly scalable analysis services cubes with new development environments. The chart below depicts significant improvements coming online with each CTP. Below, you will see the 10 new improvements in the July CTP. Click on any improvement in the chart below to explore and learn more about it. Want to find out more about the improvement groups? Each group will open to an informative video on what each means. |

Katmai (Sql 2008) - The List of New Features 
So, I've been getting quite a few pings about providing a list of new features to look for in Katmai (Sql 2008) and/or those that I'll be either blogging about and/or presenting on at the DC area groups I mentioned here: http://blogs.msdn.com/chadboyd/archive/2007/07/18/katmai-sql-server-2008-presentations-in-the-dc-area-novasql-caparea-net-cmap.aspx
Well, I put together a list below, and this isn't even everything (though it's a lot of the major stuff) - I even tried to categorize it (and some things may appear in multiple categories). I'll be blogging/presenting/etc. on many, many of these in the coming months, so stay tuned:
Security/Auditing
- Transparent Data Encryption (encryption while data is 'still' on disk, transparent to applications)
- External Key Management (Consolidation of key management, integration with external products)
- Data Auditing (1st-class 'AUDIT' objects; DDL support; audit objects, principals, data, etc.; support for multiple logging targets)
Availability/Reliability
- Pluggable CPU support
- Enhanced Database Mirroring (compression of mirror streams, enhanced performance, automatic page-level repair for principal/mirror)
Performance
- Data compression (easy to enable/disable online, more efficient data storage (this is NOT traditional data compression))
- Backup stream compression (server level control or backup statement control, all backup types)
- Performance data collection (single, common framework for data collection, reporting, and storage/warehousing)
- Improved Plan Guide support (plan freezing, pull plans directly from plan cache, SSMS integration, etc.)
- Resource Governor (create pools and groups to govern, define classifications based on built-in functions, segment resource utilization amoung groups)
Management
- Policy-based management framework (manage via policies vs. scripts, enterprise-wide support, automated monitoring/enforcement, etc.)
- Integrate with Microsoft System Center
- Extended Events (high perf lightweight tracing infrastructure, NOT sql trace, integrated with ETW, unprecidented insight into goings-on)
Development Enhancements
- Improved datetime datatypes (100th nanosecond precision (7 digits past second), time-zone datetime offset, date only, time only)
- HierarchyID datatype (hierarchical-aware data type, ORDPath values, built-in functions, methods, etc.)
- Entity Data Model support (develop 'business entities' vs. tables, model complex relationships, retrieve entities vs. rows/columns)
- LINQ
- Sql Server Change Tracking (Change Data Capture, get 'diff' data changes WITHOUT a comparible value (i.e. datetime, timestamp, etc.))
- Table Valued Parameters
- MERGE statement ('upsert' data, also includes deletion functionality)
- Large UDT's (no more 8000 byte limit on CLR-based UDTs, no more 8000 byte limit for UDA's)
- Spatial data (GEOMETRY and GEOGRAPHY data types, built-in spatial function support, spatial indexes)
- XML enhancements (support for lax validation, office 12 support, xs:dateTime support, lists/union types, LET FLOWR support, etc.)
- Inline initialization and compound assignment
Service Broker
- New UI and Tools for working with (add/drop/edit functionality within SSMS, Diag tools, )
- Conversation Priority (set message ordering, send/receive impact, 1-10 levels)
Data Storage
- Data compression (see above)
- FILESTREAM attribute (get the 'best of both' functionality from BLOBs in the DB vs. BLOBs on filesystem, no more "to blob or not to blob")
- Integrated Full Text Search (FTS fully integrated into DB engine, no external storage, no external service, more efficient and reliable costing)
- Sparse columns (more efficient storage for 'wide' tables with many columns that repeat and don't contain data)
- New index types (spatial indexes, hierarchical indexes, FILTERED indexes (indexes on filtered values within columns), etc.)
Data Warehousing/ETL
- Partitioned Table Parallelism (no more thread limit per partition)
- Star Join support (no special syntax, optimizer based, full backward syntax support)
- Data compression (see above)
- Resource Governor (see above)
- Persistent Lookups in SSIS (no more re-querying for lookup operators, cache lookups in multiple ways, persist lookups to disk)
- Improved thread scheduling in SSIS (shared thread pool, pipeline parallelism)
- Change Data Capture (see above)
- MERGE statement (see above, great uses with slowly changing dimensions)
- Scale-out analysis services (read-only storage supports multiple AS servers)
- Subspace computations
- New Tools for Cube design
- Best Practice Design Alerting
- Backup cubes with better scalability
- Data-mining add-ins for Excell
Reporting
- IIS Agnostic Reporting Services Deployment (no IIS required to run RS any longer)
- Rich-text support
- Enhanced visualiztion (graphing)
- New Word rendering (render reports to Microsoft Word)
Deprecation
- Many 'old' features ARE REMOVED/GONE (those that have been deprecated for some time - 60/65/70 compat modes, nolog / truncateonly syntax, etc.)
