Slide 1: Microsoft Financial Services Developer Conference 2004
Slide 2: What’s New in SQL Server 2005? Roger Wolter Program Manager SQL Server Engine Microsoft Corporation
Slide 3: SQL Server “Yukon”  The scalable, secure, enterprise-class data management platform Scalability, availability, security advancements Storage of all data types, formats Focus on ease-of-use Enterprise Data Management    Leverage existing development skills Share data across any platform Provide end-to-end development tools Programmability   Business Intelligence    Scalable, comprehensive solution Real time decision making tools Extend information to employees, partners
Slide 4: Manageability - Tools  New: SQL Server Workbench    New Rich GUI Visual Studio Based UI Support all SQL Server components Managed code, new design patterns High Performance CMDLine SMTP Support, Cluster Support, Asynchronous Scale, Perf, WMI Eventing     New: Management Objects (SMO)  New: SQLCMD  New: SQLMail Replacement  Improved: SQLAgent 
Slide 5: Manageability  Dynamic Server Configuration   Goal: No Server restarts E.g. CPU Affinity doesn’t require re-start Async events on DDL   Events   Can be surfaced as WMI events Triggers on DDL DBA access to Server regardless of load No restart to kill runaway session  Dedicated Admin Connection  
Slide 6: Manageability  New Metadata Catalogue   More complete Information Read Only Views of Internal State >25 New Views in Yukon  Dynamic Management Views  
Slide 7: Availability         Improving repair Backup improvements All datatypes (full text indices, cubes ...) Filegroup granularity for simple recovery Data backups don’t block Log backups Fine-grained Online Repairs Media reliability (CheckSums) Backup Media Mirroring Online Restore  Restore/recovery improvements    Online: Page, file, filegroup granularity Much shorter outage at software upgrade - Resource Recovery database Redo committed Undo incomplete xactions FASTER: Just redo
Slide 8: Partitions    Partition Tables + Indices by range Transparent to applications Can add, drop, split, merge partitions in seconds.      Create new filegroup F Create empty version of the table F.T (no keys) Heap load F.T Index F.T Now add F.T to online table T (takes a second) Table T Table T A B C D E F F
Slide 9: Availability: Mirrored Systems  How do you deal with catastrophe    Fire, flood, storm, earthquake, power/net breakdown? Data center move Sabotage, Gremlins?    Cluster failover can take minutes  What if I want 5 -9s? (5 minutes/year) Primary Witness Mirrored Systems Two independent systems Replicas of one another    Mirror Continuous SQL log shipping Mirror tracks primary Witness breaks ties  Easy to configure and admin
Slide 10: Database Mirroring Witness  Database failover – Instant standby  Very fast … < 3 seconds   Failed Repaired Primary Primary New Mirror Primary Automatic or manual Automatic re-sync after failover     Automatic and transparent client redirect No single point of failure No special hardware; standard computers and storage Minimal impact to transaction throughput
Slide 11: Availability  Online Index build    Build index in background (table always up) (also works for rebuild/drop) No table lock – good for foreign keys too Not for XML Indexes  Database View: Read-only copy of DB
Slide 12: Security  Catalog and Metadata security  See only what you have access to   User / Schema separation Password Policy enforcement  Password strength, expiration   Certificate Based Authentication All permissions grantable
Slide 13: Full-Text Search  Performance improvements in Yukon  Indexing Performance:  Building Full-Text indexes is two orders of magnitude faster Query performance has also improved considerably (Full-Text queries are 30-50% faster) Sort by rank setting now allows extremely fast FREETEXT-based queries  Query Performance:    Scalability  Yukon Full-Text Search is capable of handling large amounts of data   Tested up to 2,000,000,000 rows of data Time to index scales nearly linearly with size of data
Slide 14: TSQL Enhancements  Snapshot Isolation   Readers don’t wait for writers Conflict detection     Recursive Queries Pivot and Unpivot Included Index columns Synonyms
Slide 15: CLR  Infrastructure, Integration  Memory, threads, SQL type library Functions, Procedures, Triggers  User defined Types, Aggregates  In-Proc Data Access (perf)  Symmetric data access   Mid-tier/data tier deployment decision  Tight integration with Visual Studio  Authoring, debugging, profiling
Slide 16: Authoring/Debugging/Deploying      New Visual Studio project type in “Whidbey” for “Yukon” managed code Server debug integration Set breakpoints anywhere Full debugger visibility Single step support:   Between languages: T-SQL, C#, VB, & C++ Between deployment tiers:  E.g. Mid-tier, through SQL Server stored proc call & back to mid-tier
Slide 17: Data Access       API Enhancements: ADO .NET V2 Multiple active result sets (MARS) Query notifications – for cache invalidation Functional parity with ADO (ADOX, etc) Asynchronous client access XML Data type support User Defined Type (UDT) support
Slide 18: SQL Web Services  Native SOAP access    Standards based access to SQL Server No client dependency Improved Interop HTTP.SYS  New “HTTP ENDPOINT” object      Configure connection info Configure authentication Expose Functions & SPs Expose TSQL Batches Configure WSDL http://myserver/sql Port: 80 Integrated Auth WebMethod = myDb.dbo.mySP HTTP Endpoint  Leverages kernel-mode listener
Slide 19: XML Support  XML Datatype   Columns, Variables, Parameters Typed or Untyped   XML Schema Collections XML Indexes   Indexes on tags, values & paths Understood by Optimizer Query Instance or Column Insert, Update, Delete Extensions Nodes() Method  XQuery   
Slide 20: SQL Service Broker  Platform for building Asynchronous, loosely coupled database applications   Queues are now database objects  Queue locking reduces conflicts and deadlocks Dialogs give unprecedented message ordering assurance  Ordered across transactions, input applications and output applications Use the same API’s and tools as SQL    New DDL and DML for messaging  Activation - the right number of readers running Reliable messaging for scale out
Slide 21: SQL Service Broker  Built into the database      Single database connection for messaging and other database operations No two-phase commits for transactional messaging Remote Receives from Transactional Queues Stored Procedure Activation Backup and failover of messages  Messages have the same integrity guarantees as other database data - Clusters, Database Mirroring, etc. Backup, space management, security  Shared management platform with database 
Slide 22: Data Types  Varchar(1-8000), Nvarchar(1-4000), Varbinary(1-8000)   Maximum column length still 8,000 bytes Rows can now exceed page size  Varchar(max), Nvarchar(max), Varbinary(max)   Can hold greater than 8000 characters / bytes Same programming model as limited types   XML – A full-fledged data type UDTs – User-defined Data Types using CLR
Slide 23: Oracle Publishing Transactional Replication    Designed specifically for Oracle Publishers v8+ on any operating system No Oracle side software install necessary Requires minimal knowledge of Oracle Standard Transactional and Snapshot Publications Administered like SQL Server, from SQL Server    Leverages existing SQL Server skills  Yukon Distributor Subscribers
