Integration with Visual Studio® and .NET
Native XML technology
Interoperability: open standards, Web services
Developer Productivity
Comprehensive ETL solution
Real-time decision making: reporting, data mining
Scalability and availability enhancements
Business
Intelligence
Secure, reliable, and productive database platform
for line-of-business and analytical applications

6. Manageability Tools New: SQL Server Management Studio
New rich GUI
Integrated authoring, management
Supports all SQL Server components
Replaces Enterprise Manager, Query Analyzer
Can manage multiple servers

7. Manageability Management Studio
Object Explorer
Create databases and data sources
Control privileges and permissions
Configure replication
Manage SQL Server Agent

8. Manageability SQLCMD
Command-line tool for executing T-SQL statements and scripts
Replaces osql
Uses OLE DB (not ODBC or DB-Library)
Has a dedicated administrator connection

9. Manageability SQLiMail
Uses SMTP, not Extended MAPI
Profiles
Secure – Profiles enable specification of users with access to SQLiMail profile
Integrated management within SQL Server
Failover – can point to multiple SMTP servers from one profile for ensured mail delivery
Service Broker used to deliver messages to avoid blocking a stored procedure
Execute sendimail_sp

10. Manageability Tuning Tools
XML Show Plan
Publicly available Schema
Programmatic access
Portability
Database Tuning Advisor
Time bound tuning
What-if analysis
Scalability

11. Manageability Diagnostic Tools
Dynamic Management Views
Server transparency
“sys.memory_clerks”
“sys.schedulers”
SQL Profiler
Integrated with Performance Monitor
Deadlock graph
Integrated Event Logs

12. Security Feature Enhancements
Auditing
DDL triggers
Events
Authorization Enhancements
User schema separation
Module execution context
Catalog security
Granular permission control
Encryption enhancements

13. Security User-Schema Separation
New DDL for user and schemas
CREATE/ALTER/DROP for USER, ROLE, and SCHEMA
Dropping user does not require application rewrite

14. Security DROP USER => Application Rewrite
SELECT custID FROM User1.OrdersTable
Owning user = User1
SCHEMA = User1
App1
Owning user = User2
SCHEMA = User2
App1 Modified
OrdersTable
SELECT custID FROM User2.OrdersTable
Exec User1.InsertOrderProc
App2
InsertOrderProc
App2 modified
Exec User2.InsertOrderProc

15. Security Solution: User-Schema Separation
Table
View
Stored Proc
Function
User 2
Owned by
Owned By
Database Object
Contained in
Owned by
Schema
User
Drop user does NOT require application change!

16. Security User-Schema Separation
Each schema has an owning principal – user or role
Each user has a default schema for name resolution
Object creation inside schema requires CREATE permission and ALTER or CONTROL permission on the schema
Example: Creation of table in schema requires CREATE TABLE permission and ownership of schema or ALTER or CONTROL on schema
Database
Approle1
User1
Role1
Has default schema
Owns
Owns
Schema1
Owns
Schema2
Schema3
SP1
Fn1
Tab1

17. Security Execution Context
Execute Perms checked for User3
Select Perms checked for User3
SQL Server 2000
User2.Proc1
User1.T1
User 3
User1.Proc1
User1.T1
Execute Perms checked for User3
NO Perms checked for User3
SQL Server 2005
User 3
User2.Proc1
User1.T1
‘Execute AS ‘X’ ’
Execute Perms checked for User3
Select Perms checked for ‘X’.
Not for user3

18. Security Module Execution Context
Execute AS CALLER
Execute AS “UserName”
Execute AS SELF
Execute AS OWNER
<SLIDETITLE>Module Execution Context</SLIDETITLE>
<KEYWORDS></KEYWORDS>
<KEYMESSAGE>Module Execution Context allows you to change how module is executed.</KEYMESSAGE>
<SLIDEBUILDS>4</SLIDEBUILDS>
<SLIDESCRIPT>With module execution context, you have more flexibility in executing statements.
Build 1: They can be executed as they were in SQL Server 2000, as the caller; this is the default behavior.
Build 2: But in addition, you can create a module and specify that it will be executed as a specified user. In this case, the user calling the code would need impersonation permission on the user specified.
Build 3: You can also specify that the module will execute as yourself. In other words, since you are specifying that there will be an execute as clause, it will always execute as you. This is useful when a variety of people and applications may be calling the module you have created.
Build 4: The last execution context is that the module will execute as the owner. This means that when the ownership changes, the context will be that of the new owner.
</SLIDESCRIPT>
<SLIDETRANSITION>In addition to these security enhancements, there are new encryption and key management features.</SLIDETRANSITION>
<ADDITIONALINFORMATION><ITEM></ITEM></ADDITIONALINFORMATION>

19. Security Certificates
Encryption enhancements
Encryption uses symmetric keys, asymmetric keys and certificates
SQL Server 2005 can generate certificates for encryption
RC4, RSA, Triple-DES and AES encryption supported
Encryption can be used with any level of SQL Server 2005 securable

20. Availability Table Partitioning
SQL Server 2000 allowed partition views
SQL Server 2005 allows partitioned tables and indexes
Increases performance on multiprocessor machines
Eases management of data – data can be grouped logically
Data movement easier
Three steps
Create the partition function
Create the partition scheme
Create the partitioned table

21. Availability Replication Changes
Stand-alone Replication Monitor
Merge performance and scalability improved 2-4x
DDL on published objects supported seamlessly while replicating
New peer-to-peer replication wizard

22. Availability Web Synchronization
Merge replication
Subscriber
IIS
Publisher/Distributor
-InternetUrl
Replisapi.dll
Firewall

23. Availability Other Maintenance Features
Dedicated Admin Connection
Access to Server when regular connections fail
Online page and file restore
Database remains online – only data being restored is unavailable
Fast recovery
Database is available when undo begins
Redo
Undo
Available

24. Session Summary New integrated management tools
Secure by design, by deployment, and by default
Expanded and enhanced availability options
