SQL server
SQL SQL is Structured Query Language English acronym, which means for the Structured Query Language.SQL language is the main function of establishing ties with the various databases, for communication.In accordance with ANSI (American Nationa l Standards Institute) requirements,SQL as a relational database management system standard language.SQL statements can be used to implement a wide range of operations, such as updating the data in the database, extract data from the database and so on.At present, the vast majority of the popular relational database ma nagement systems such as Oracle, Sybase, Microsoft SQL Server , Acce, adopted the standard SQL language.Although many databases on the SQL statement for the redevelopment and expansion, but including the Select, Insert, Update, Delete, Create, and Drop, including the standard SQL commands can be used to complete almost all the database operations.SQL Server
SQL Server is a relational database management system.It was originally proposed by Microsoft Sybase and Ashton-T ate three companies jointly developed in 1988 with the introduction of the first OS / 2 version.After the introduction of Windows NT in, Microsoft and Sybase in the development of SQL Server on the split,Microsoft will migrate to SQL Server on Windows NT system, focusing on promoting the development of SQL Server version of Windows NT .Sybase is more focused on SQL Server in the UNIX operating system applications.SQL Server 2000 is Microsoft Launches the SQL Server data base management system, the inherited version of SQL Server 7.0 version of the merits, at the same time it increases than many of the more advanced features.Good scalability with ease of use and related high degree of software

SQL SQL是英文 Structured Query Language 的缩写， 意思为结构化查询语言。 SQL 语言的主要功能就是同各种数据库建立联系，进行沟通。按照 ANSI(美国国家标准协会)的规定，SQL被作为关系型数据库管理系统的标准语言。SQL 语句可以用来执行各种各样的操作，例如更新数据库中的数据， 从数据库中提取数据等。 目前， 绝大多数流行的关系型数据库管理系统，如 Oracle, Sybase, Microsoft SQL Server , Acce 等都采用了 SQL 语言标准。虽然很多数据库都对 SQL 语句进行了再开发和扩展， 但是包括 Select, Insert, Update, Delete, Create,以及Drop 在内的标准的 SQL 命令仍然可以被用来完成几乎所有的数据库操作。
SQL Server SQL Server是一个关系数据库管理系统。它最初是由Microsoft Sybase和 Ashton-Tate三家公司共同开发的,于1988年推出了第一个OS/2版本。
在 Windows NT推出后, Microsoft与 Sybase在 SQL Server的开发上就分道扬镳了， Microsoft将SQL Server移植到Windows NT系统上，专注于开发推广 SQL Server的Windows NT版本。Sybase则较专注于SQL Server在UNIX操作系统上的应用。SQL Server 2000是Microsoft公司推出SQL Server数据库管理系统，该版本继承SQL Server 7.0版本的优点,同时又比它增加了许多更先进的功能.具有使用方便可伸缩性好与相关软件集成程度高等优点,可跨越从运行 Microsoft Windows 98的膝上型电脑到运行Microsoft Windows 2000的大型多处理器的服务器等多种平台使用。

微软 SQL Server 2008 SQL Server 2008是一个重大的产品版本，它推出了许多新的特性和关键的改进，使得它成为至今为止的最强大和最全面的SQL Server版本。Server 2008 中的新的特性、优点和功能……
微软的这个数据平台满足这些数据爆炸和下一代数据驱动应用程序的需求， 支持数据平台愿景：关键任务企业数据平台、动态开发、关系数据和商业智能。
Microsoft 数据平台愿景 SQL Server 的愿景
许多因素致使产生了信息存储爆炸.有了新的信息类型，例如图片和视频的数字化，和从RFID 标签获得的传感器信息，公司的数字信息的数量在急剧增长。遵守规范和全球化的发展要求信息存储的安全性和在任何时候都可用。同时，磁盘存储的成本显著地降低了，使得公司投资的每一美元可以存储更多的数据。用户必须快速的在大量的数据中找到相关的信息。此外，他们想在任何设备上使用这个信息，并且计划每天使用，例如 Microsoft Office系统应用程序。对数据爆炸和用户期望值的增加的管理为公司制造了许多挑战。数据平台愿景提供了一个解决方案来满足这些需求，这个解决方案就是公司可以使用存储和管理许多数据类型，包括 XML、e-mail、时间/日历、文件、文档、地理等等，同时提供一个丰富的服务集合来与数据交互作用：搜索、查询、数据分析、报表、数据整合，和强大的同步功能。用户可以访问从创建到存档于任何设备的信息，从桌面到移动设

备的信息
这个平台有以下特点：
· 可信任的——使得公司可以以很高的安全性、可靠性和可扩展性来运行他们最关键任务的应用程序。
· 高效的——使得公司可以降低开发和管理他们的数据基础设施的时间和成本。
· 智能的——提供了一个全面的平台，可以在你的用户需要的时候给他发送观察和信息。
一、可信任的
（一）保护你的信息
在过去的SQL Server 2005的基础之上，SQL Server 2008做了以下方面的增强来扩展它的安全性：
* 简单的数据加密
SQL Server 2008可以对整个数据库、数据文件和日志文件进行加密，而不需要改动应用程序。进行加密使公司可以满足遵守规范和及其关注数据隐私的要求。 简单的数据加密的好处包括使用任何范围或模糊查询搜索加密的数据、加强数据安全性以防止未授权的用户访问、还有数据加密。这些可以在不改变已有的应用程序的情况下进行。
* 外键管理
SQL Server 2008为加密和密钥管理提供了一个全面的解决方案。为了满足断发展的对数据中心的信息的更强安全性的需求，公司投资给供应商来管理公司内的安全密钥。SQL Server 2008 通过支持第三方密钥管理和硬件安全模块(HSM)产品为这个需求提供了很好的支持。
* 增强了审查
SQL Server 2008使你可以审查你的数据的操作，从而提高了遵从性和安全性。审查不只包括对数据修改的所有信息，还包括关于什么时候对数据进行读取的信息。SQL Server 2008具有像服务器中加强的审查的配置和管理这样的功能，这使

得公司可以满足各种规范需求。SQL Server 2008还可以定义每一个数据库的审查规范，所以审查配置可以为每一个数据库作单独的制定。为指定对象作审查配置使审查的执行性能更好，配置的灵活性也更高。
（二）确保业务可持续性
* 改进了数据库镜像SQL Server 2008 基于SQL Server 2005,并提供了更可靠的加强了数据库镜像的平台。新的特性包括：
·页面自动修复。SQL Server 2008通过请求获得一个从镜像合作机器上得到的出错页面的重新拷贝，使主要的和镜像的计算机可以透明的修复数据页面上的 823和824错误。
· 提高了性能.SQL Server 2008压缩了输出的日志流，以便使数据库镜像所要求的网络带宽达到最小。
