      1.4. Overview of the MySQL Database Management System


      MySQL, the most popular Open Source SQL database management system, is developed, distributed, and supported by MySQL AB. MySQL AB is a commercial company, founded by the MySQL developers. It is a second generation Open Source company that unites Open Source values and methodology with a successful business model.

      MySQL是最流行的公开源代码SQL数据库管理系统,由MySQL AB 开发,宣传和支持的。MySQL是一个商业公司,由MySQL 开发者创立。它是第二代整合了开放资源值和方法论的开放资源公司的成功运作模式。
The MySQL Web site (http://www.mysql.com/) provides the latest information about MySQL software and MySQL AB.

      · MySQL is a database management system.


      A database is a structured collection of data. It may be anything from a simple shopping list to a picture gallery or the vast amounts of information in a corporate network. To add, access, and process data stored in a computer database, you need a database management system such as MySQL Server. Since computers are very good at handling large amounts of data, database management systems play a central role in computing, as standalone utilities or as parts of other applications.

      数据库是数据结构化的收集。它可以是从一个简单的购物单到一个图片图库或是收集在公众网络的大量信息。为了添加,输入和处理储存在计算机数据库里的数据,你需要一个如MySQL 服务器的数据库管理系统。 因为计算机非常善于处理大量的数据,数据库管理系统在计算中起到很重要的作用。

      · MySQL is a relational database management system. 

      A relational database stores data in separate tables rather than putting all the data in one big storeroom. This adds speed and flexibility. The SQL part of “MySQL” stands for “Structured Query Language.” SQL is the most common standardized language used to access databases and is defined by the ANSI/ISO SQL Standard. The SQL standard has been evolving since 1986 and several versions exist. In this manual, “SQL-92” refers to the standard released in 1992, “SQL:1999” refers to the standard released in 1999, and “SQL:2003” refers to the current version of the standard. We use the phrase “the SQL standard” to mean the current version of the SQL Standard at any time.

      一个关系数据库存储在不同的表格里,而不是把它们放在一个大的存储室里。因为可以提高速度和灵活性。“MySQL”中的SQL表示“结构询问语言”。SQL是最大众化标准语言,是用来进入数据库的,它是由ANSI/ISO SQL 标准定义的。自1986年起就开始使用SQL标准,并且也出现了几个版本。在本手册中,“SQL-92”表示1992年发布的标准,“SQL:1999”表示1999年发布的标准,“SQL:2003”表示目前的标准版本。我们使用短语“the SQL 标准”的意思是在任何时候的SQL标准的版本。
      · MySQL software is Open Source. 


      Open Source means that it is possible for anyone to use and modify the software. Anybody can download the MySQL software from the Internet and use it without paying anything. If you wish, you may study the source code and change it to suit your needs. The MySQL software uses the GPL (GNU General Public License), http://www.fsf.org/licenses/, to define what you may and may not do with the software in different situations. If you feel uncomfortable with the GPL or need to embed MySQL code into a commercial application, you can buy a commercially licensed version from us. See the MySQL Licensing Overview for more information (http://www.mysql.com/company/legal/licensing/).

      开放资源的意思就是允许任何人使用和修改软件。任何人都可以从互联网下载免费使用MySQL软件。如果你想,你可以学习源代码,也可根据你的需求进行修改。MySQL软件使用GPL(GNU General Public License)来详细说明在不同的情况下,软件起到的作用,参看http://www.fsf.org/licenses/。若你不习惯用GPL或者需要将MySQL代码插入到一个商业应用中,你可以从我处购买一个商业许可的版本。

      · The MySQL Database Server is very fast, reliable, and easy to use. 

      If that is what you are looking for, you should give it a try. MySQL Server also has a practical set of features developed in close cooperation with our users. You can find a performance comparison of MySQL Server with other database managers on our benchmark page. See Section 7.1.4, “The MySQL Benchmark Suite”.

      若是你想要的, 你可以再尝试一下。MySQL 服务器和用户也有着紧密的关系。在基准页上你可以找到MySQL服务器和其他数据库管理器上功能的对比。详细参看:Section 7.1.4, “The MySQL Benchmark Suite”.

      MySQL Server was originally developed to handle large databases much faster than existing solutions and has been successfully used in highly demanding production environments for several years. Although under constant development, MySQL Server today offers a rich and useful set of functions. Its connectivity, speed, and security make MySQL Server highly suited for accessing databases on the Internet.


      · MySQL Server works in client/server or embedded systems. 


      The MySQL Database Software is a client/server system that consists of a multi-threaded SQL server that supports different backends, several different client programs and libraries, administrative tools, and a wide range of application programming interfaces (APIs).


      We also provide MySQL Server as an embedded multi-threaded library that you can link into your application to get a smaller, faster, easier-to-manage standalone product.


      · A large amount of contributed MySQL software is available.


      It is very likely that your favorite application or language supports the MySQL Database Server.


      The official way to pronounce “MySQL” is “My Ess Que Ell” (not “my sequel”), but we don't mind if you pronounce it as “my sequel” or in some other localized way.

      官方说“MySQL”的说法是“My Ess Que Ell”(而不是“my sequel”),但是我们不介意你们发“my sequel”或是其他什么叫法。
