2. 2 SQL Server Yukon The scalable, secure, enterprise-class data management platform Enterprise Data Management Programmability BusinessIntelligence AGENDA  Enterprise Data Management  Scalability, Performance, & 64 bit  Online operations & enhanced availability  Programmability  Industry leading server-side programming model  Native XML datatype support  Web services  Service Broker  Business Intelligence  OLAP Server  Data mining  Reporting Server  Data Transformation Services

3. 3 Cost SavingsScalability The highly scalable database platform for memory intensive, performance-critical business applications  Optimized for Windows Server 2003 & 64 bit H/W  Great performance Large memory addressability (up to 32 TB) Large memory addressability (up to 32 TB) Nearly unlimited virtual memory (up to 8 TB) Nearly unlimited virtual memory (up to 8 TB) I/O savings due to larger memory buffer pools I/O savings due to larger memory buffer pools  T-SQL code-compatibility with SQL Server 2000  8 node shared disk fail-over support  Same on-disk format as 32-bit for easy migration  One setup for database & OLAP based on Windows Installer technology  Compelling alternative to expensive Unix solutions Manageability Economic

4. 4 Dynamic Online Configuration  Most DB configuration is Dynamic  No longer requires a server restart  Only I/O Affinity remains static  Memory added W/O restart or reboot  Eliminates one cause of planned failover  Requires: Appropriate H/W & Windows Server 2003  Address Windowing Extensions (AWE)  Changes to physical size don’t require downtime  Dynamically configurable (Min / Max)  Maximum limited by physical memory  Dynamically adjusts to “hot-add” memory  Requires Windows Server 2003

5. 5 Snapshot Isolation  New transaction isolation level  Existing isolation levels unchanged  Serializable, repeatable read, read committed, & read uncommitted  Increased Data Availability for read dominated applications  Non-Blocking consistent reads in OLTP environment  Writers don’t block readers  Readers don’t block writers  Allows writes, which can cause conflicts  Includes mandatory conflict detection

6. 6 Online Index Operations  Online index operations now allow concurrent modification of the underlying table or index  Updates, Inserts, Deletes  Online Index Maintenance  Create, Rebuild, Drop  Reorganize (including BLOBs)  Index-based constraints (PK, Unique)  Simple DDL for both Online/Offline operations  Updates incur some additional cost during an online index operation  Maintains old & new indexes during maintenance

7. 7 Fast Recovery Restart or Restore  SQL Server 2000  Database is Available after Undo Completes  Yukon  Database is Available when Undo Begins UndoRedo Available UndoRedo Available Time

8. 8 Database View  Read-only, consistent copy of a database  Good for reporting state of DB at single point in time  Supports fast primary DB rollback to view  Correction of DBA or user/programmer error  Unchanging as database is modified  Fast & efficient  Copy-on-Write  Storage only required for DB changes  Can be created for any database

9. 9 Database Mirroring  Database Failover – an Instant Standby  Very Fast … expect well under 8 seconds  Automatic or manual failover  Zero data loss  Automatic re-sync after failover  Hardware  Works with standard computers and storage  No shared storage components  Impact to transaction throughput  Zero to minimal  Automatic, transparent client redirect  Use ViewPoint to make mirror database a readable reporting database

11. 11 SQL Server Yukon The scalable, secure, enterprise-class data management platform Enterprise Data Management Programmability BusinessIntelligence Server-side programming model Multiple languages: T-SQL, VB.NET, C#… Existing tools/processes Leverage existing development skills T-SQL enhancements Full text search Relational-to-XML mapping XML native datatype SQL Web Services SQL Service Broker

12. 12. NET Framework Integration Key Features  Server side programming:  VB.net, C++.net, & C#  Programming environment for:  Functions, Procedures, Triggers  User Defined Types, Aggregates  In-Proc Data Access (ADO.NET V2)  Symmetric data access  Mid-tier/data tier deployment decision  Security  Three levels of code access security  Safe, External-Access (verifiable), Unsafe  Tight integration with Visual Studio  Authoring, debugging, deployment, profiling  Tool support includes T-SQL

13. 13 VS.NET Project Assembly: “TaxLib.dll” VB,C#,C++ Build SQL Server SQL Data Definition: SQL Data Definition: create assembly … create function … create procedure … create trigger … create type … SQL Queries: tax(sal,state) select sum(tax(sal,state)) from Emp where county = ‘King’ Runtime hosted by SQL (in-proc) The Developer Experience

14. 14.NET Integration Key Theme: Choice & Control  Choice of where to run logic  Database, for logic that runs close to data  Mid-tier, for logic that scales out  Symmetric programming model  Leverage skills mid-tier & server  Choice of programming language  C#, VB.NET, & Managed C++, for a safe, modern execution environment  TSQL continues to be supported & enhanced  Good choice for data-intensive procedures  Safe extended stored proc replacement

15. 15 T-SQL Enhancements  Varchar(max), Varbinary(max)  Alternative to Text, Image  Uniform Programming model  T-SQL Exception Handling  Recursive Queries  Multiple Active Result Sets  Statement-level recompile  Fewer recompiles & less costly  Other  Pivot, UnPivot, Top (expression)  DDL triggers  Queuing primitives

16. 16 Full-text Enhancements  Performance & Scalability  Index and Query Performance  Early testing to over 2B rows  Index cost scales near linearly with data size  Administrative integration  Transportability via database attach/detach  Integrated backup, restore & recovery  Full-Text DDL for easier administration  Functionality  Thesaurus  Diacritic sensitivity/insensitivity  Multi-column full-text queries supported  CONTAINS((col1,col2), ‘Yukon’)  Support for XML data type

17. 17 XML Scenarios 1) Data Exchange… XML data Manufacturer Supplier Platform independent transport format Platform independent transport format Loosely-coupled systems Loosely-coupled systems B2B, B2C, work flow, … B2B, B2C, work flow, … Solution : Solution : For XML: Return SQL Query results as XML For XML: Return SQL Query results as XML Annotated views: Define XML view over relational data Annotated views: Define XML view over relational data

18. 18 XML Scenarios 2) Semi-structured storage…  XML Datatype  Loosely structured data or dynamic schema  Solution:  Native XML datatype  Column, variable, or paramater with optional schema (XSD)  Query(): Include xquery over XML as part of SQL Statements  Fully integrated supporting correlations etc.  OpenXML: XML content available via rowset First Name Last Name AddressPhone XML data type
