What's New in SQL Server 2005

Enterprise Data Management
In today's connected world, data and the systems that manage that data must always be secure yet available to your users. With SQL Server 2005, users and Information Technology professionals across your organization will benefit from reduced application downtime, increased scalability and performance, and tight yet flexible security controls. SQL Server 2005 also includes many new and improved capabilities to help make your Information Technology staff more productive. SQL Server 2005 includes key enhancements to enterprise data management in the following areas:

  • Manageability

  • Availability

  • Scalability

  • Security

Manageability
SQL Server 2005 makes it simpler and easier to deploy, manage, and optimize enterprise data and analytical applications. As an enterprise data management platform, it provides a single management console that enables data administrators anywhere in your organization to monitor, manage, and tune all of the databases and associated services across your enterprise. It provides an extensible management infrastructure that can be easily programmed using SQL Management Objects (SMO), enabling users to customize and extend their management environment and Independent Software Vendors (ISVs) to build additional tools and functionality to further extend the capabilities that come out of the box.

SQL Server Management Studio
SQL Server 2005 simplifies management by providing one integrated management console to monitor and manage the SQL Server relational database, as well as Integration Services, Analysis Services, Reporting Services, Notification Services, and SQL Mobile across large numbers of distributed servers and databases. Database administrators can perform several tasks at the same time including: authoring and executing a query, viewing server objects, managing an object, monitoring system activity, and viewing online help. SQL Server Management Studio hosts a development environment for authoring, editing and managing scripts and stored procedures using Transact-SQL, Multidimensional Expressions (MDX), XMLA, and SQL Server Mobile Edition. Management Studio is readily integrated with source control. Management Studio also hosts tools for scheduling SQL Server Agent jobs and managing maintenance plans to automate daily maintenance and operation tasks. The integration of management and authoring in a single tool coupled with the ability to manage all types of servers provides enhanced productivity for database administrators.

Proactive Performance Monitoring and Performance Tuning
SQL Server 2005 exposes more than 70 new measures of internal database performance and resource usage from memory, locking, and scheduling to transactions and network and disk I/O. These Dynamic Management Views (DMVs) provide greater transparency and visibility into the database and a powerful infrastructure for proactive monitoring of database health and performance.

SQL Management Objects
SQL Management Objects (SMO) is a new set of programming objects that exposes all of the management functionality of the SQL Server database. In fact, Management Studio was built with SQL Management Objects. SMO is implemented as a Microsoft .NET Framework assembly. You can use SMO to automate common SQL Server administrative tasks, such as programmatically retrieving configuration settings, creating new databases, applying Transact-SQL scripts, creating SQL Server Agent jobs, and scheduling backups. The SMO object model is a more secure, reliable, and scalable replacement for Distributed Management Objects (DMO), which was included with earlier versions of SQL Server.

Availability
Investments in high availability technologies, additional backup and restore capabilities, and replication enhancements will enable enterprises to build and deploy highly available applications. Innovative high availability features such as; database mirroring, failover clustering, database snapshots, and enhanced online operations will minimize downtime and help to ensure that critical enterprise systems remain accessible. We will review these enhancements in greater detail in this section.

Database Mirroring
Database mirroring allows continuous streaming of the transaction log from a source server to a single destination server. In the event of a failure of the primary system, applications can immediately reconnect to the database on the secondary server. The secondary instance detects failure of the primary server within seconds and accepts database connections immediately. Database mirroring works on standard server hardware and requires no special storage or controllers.

Failover Clustering
Failover clustering is a high availability solution that exploits Microsoft Windows Clustering Services to create fault-tolerant virtual servers that provide fast failover in the event of a database server failure. In SQL Server 2005, support for failover clustering has been extended to SQL Server Analysis Services, Notification Services, and SQL Server replication. The maximum number of cluster nodes has been increased to eight. SQL Server failover clustering is now a complete fault-tolerant server solution.

Database Snapshots
SQL Server 2005 introduces the ability for database administrators to create instant, read-only views of a database. The database snapshot provides a stable view without the time or storage overhead of creating a complete copy of the database. As the primary database diverges from the snapshot, the snapshot adds its own copy of pages as they are modified. Thus the snapshot may be used to quickly recover from an accidental change to a database by simply reapplying the original pages from the snapshot to the primary database.

Fast Recovery
SQL Server 2005 improves the availability of SQL Server databases with a new faster recovery option. Users can reconnect to a recovering database after the transaction log has been rolled forward. Earlier versions of SQL Server required users to wait until incomplete transactions had rolled back, even if the users did not need to access the affected parts of the database.

Dedicated Administrator Connection
SQL Server 2005 introduces a dedicated administrator connection to access a running server even if the server is not responding or is otherwise unavailable. This allows you to execute diagnostic functions or Transact-SQL statements in order to troubleshoot problems on a server. The connection is activated by members of the sysadmin fixed server role and is only available through the SQLCMD command prompt utility either locally, or from a remote machine.

Online Operations (index operations and restore)
The ability to create, rebuild, or drop an index online is an enhanced feature of SQL Server 2005 that augments the indexing capabilities of earlier versions of SQL Server. The online index option allows concurrent modifications (updates, deletes, and inserts) to the underlying table or clustered index data and any associated indexes during index data definition language (DDL) execution. With support for online index operations, you can add indexes without interfering with access to tables or other existing indexes. Additionally, the server workload allows index operations to take advantage of parallel processing.

SQL Server 2005 also introduces the ability to perform a restore operation while an instance of SQL Server is running. Online restoration capabilities improve the availability of SQL Server because only the data that is being restored is unavailable. The rest of the database remains online and available. Earlier versions of SQL Server require that you bring a database offline before you restore the database.

Replication
Replication is designed to increase data availability by distributing the data across multiple database servers. Availability is increased by allowing applications to scale out the SQL Server read workload across databases. SQL Server 2005 offers enhanced replication using a new peer-to-peer model that provides a new topology in which databases can be synchronized transactionally with any identical peer database.

Scalability
Scalability advancements such as table partitioning, snapshot isolation, and 64-bit support will enable you to build and deploy your most demanding applications using SQL Server 2005. The partitioning of large tables and indexes significantly enhances query performance against very large databases.

Table and Index Partitioning
Table and index partitioning eases the management of large databases by facilitating the management of the database in smaller, more manageable chunks. While the concept of partitioning data across tables, databases, and servers is not new to the world of databases, SQL Server 2005 provides a new capability for the partitioning of tables across filegroups in a database. Horizontal partitioning allows for the division of a table into smaller groupings based on a partitioning scheme. Table partitioning is designed for very large databases, from hundreds of gigabytes to terabytes and beyond.

Snapshot Isolation
Once data is copied, transformed, and archived to an analysis-oriented database it must be maintained and/or rebuilt periodically. Users certainly benefit from looking at a transactionally consistent version of the database; however, the version of the data that they are viewing is no longer current. It can take many hours to build and index and this is where snapshot isolation comes in. The snapshot isolation level allows users to access the last row that was committed, by using a transactionally consistent view of the database. This new isolation level provides the following benefits:

  • Increased data availability for read-only applications.
  • Nonblocking read operations allowed in an OLTP environment.
  • Automatic mandatory conflict detection for write transactions.
  • Simplified migration of applications from Oracle to SQL Server.

Replication Monitor
Replication Monitor is a tool that sets a new standard for ease of use in managing complex data replication operations with its intuitive user interface and wealth of data metrics.

Support for 64-Bit System Itanium and x64
Optimized for the Intel Itanium processor, SQL Server (64-bit) takes advantage of advanced memory addressing capabilities for essential resources such as buffer pools, caches, and sort heaps, reducing the need to perform multiple I/O operations to bring data in and out of memory from disk. Greater processing capacity without the penalties of I/O latency opens the door to new levels of application scalability.

Windows Server 2003 x64 provides high performance for both 32-bit and 64-bit applications on the same system. The underlying architecture is based on 64-bit extensions to the industry-standard x86 instruction set, allowing today's 32-bit applications to run natively on x64 processors. At the same time, new 64-bit applications are executed in 64-bit mode, which processes more data per clock cycle, allows greater access to memory, and speeds numeric calculations. The end result is a platform that leverages the existing wealth of 32-bit applications while also providing a smooth migration path to 64-bit computing.

Security
SQL Server 2005 makes significant enhancements to the security model of the database platform, with the intention of providing more precise and flexible control to enable tighter security of the data. A considerable investment has been made in a number of features to provide a high level of security for your enterprise data including:

  • Enforcing policies for SQL Server login passwords in the authentication space.
  • Providing for more granularity in terms of specifying permissions at various scopes in the authorization space.
  • Allowing for the separation of owners and schemas in the security management space.

Authorization
A new security model in SQL Server 2005 allows administrators to manage permissions at a granular level and at a designated scope, making management of permissions easier as well as ensuring that the principle of least privileges is upheld. SQL Server 2005 allows you to specify a context under which statements in a module execute. This feature also acts as an excellent mechanism for granular permission management.

Authentication
SQL Server 2005 clustering supports Kerberos authentication against a SQL Server 2005 virtual server. Administrators can specify Microsoft Windows-style policies on standard logins so that a consistent policy is applied across all accounts in the domain.

Native Encryption
SQL Server 2005 supports encryption capabilities within the database itself, fully integrated with a key management infrastructure. By default, client/server communications are encrypted. To centralize security assurance, server policy can be defined to reject unencrypted communications.

SQL and Trustworthy Computing
The Trustworthy Computing initiative outlines a framework that defines the steps necessary to support secure computing as well as measures that help you deploy and maintain a secure environment. These steps help to protect the confidentiality, integrity, and availability of data and systems at every phase of the software life cycle—from design, to delivery, to maintenance. To uphold the four tenets of the Trustworthy Computing initiative, Microsoft and the SQL Server team have taken the following steps:

  • Secure by design. The SQL Server development team conducted multiple security audits and spent more than two months studying SQL Server components and the interaction between them. For each potential security threat, the team did a threat analysis to evaluate the issue and completed additional design and testing work to neutralize potential security issues. As a result of these design efforts, SQL Server 2005 includes many new server security features.

  • Secure by default. Upon installation, SQL Server 2005 chooses the right set of configuration values for all setup options, ensuring that when a new system is installed, it will be in a secure state by default.

  • Secure in deployment. Microsoft has created content to help organizations deploy SQL Server using the proper security credentials and to fully understand the steps and permissions required. SQL Server deployment tools provide the information necessary to understand the decisions you need to make during deployment. Security updates are easy to find and install—and if you choose the option, the updates install automatically. Tools are also available to help you assess and manage security risks across organizations.

Developer Productivity
SQL Server 2005 includes many new technologies that bring significant increases in developer productivity. From .NET Framework support to tight integration with Visual Studio, these features provide developers with the ability to more easily create secure, robust database applications at a lower cost. SQL Server 2005 enables developers to leverage existing skills across a variety of development languages while providing an end-to-end development environment for the database. Native XML capabilities will also allow developers to build new classes of connected applications across any platform or device.

Enhancements for developer productivity include:

  • Expanded language support

  • Improved development tools

  • Extensibility

  • Improved data access

  • XML and Web services

  • Application Framework

SQL Server Express
More than ever developers are leveraging relational databases to provide a rich end-user experience. Protecting and managing information inside these applications is critical. Microsoft SQL Server Express helps developers build robust and reliable applications by providing a free, easy to use, and robust database. Too often database systems are overly complex for building simple applications. Microsoft Visual Studio 2005 and SQL Server Express reduce this complexity by providing a simple but powerful development environment for building data-driven applications. Developers can design schemas, add data, and query local databases, all inside the Visual Studio 2005 environment. If developers need more advanced database features, then SQL Server Express can be seamlessly upgraded to more sophisticated versions of SQL Server.

Features comparison
Microsoft has redesigned the SQL Server 2005 product family to better meet the needs of each customer segment with four new editions: Express, Workgroup, Standard, and Enterprise. As a low-cost mainstream database, SQL Server 2005 will deliver unprecedented value and functionality compared with competitive solutions. The four new editions will offer a range of features, from high availability and robust scalability to advanced business intelligence tools, designed to empower users across an organization through a more secure, reliable, and productive data management platform. Additionally, with the reduced application downtime, robust scalability and performance, and tight security controls, SQL Server 2005 represents a dramatic step forward in supporting the most demanding enterprise systems in the world. Because SQL Server is part of Windows Server System, customers also receive the added benefits of reduced total cost of ownership and faster development time through the increased manageability and integration that result from the common engineering strategy implemented across Windows Server System products.
