SQL(Structured Query lAnguage，结构查询语言)是一个功能强大的数据库语言。SQL通常使用于数据库的通讯。ANSI（美国国家标准学会）声称，SQL是关系数据库管理系统的标准语言。SQL语句通常用于完成一些数据库的操作任务，比如在数据库中更新数据，或者从数据库中检索数据。使用SQL的常见关系数据库管理系统有：Oracle、 Sybase、 Microsoft SQL Server、 Access等等。虽然绝大多数的数据库系统使用SQL，但是它们同样有它们自立另外的专有扩展功能用于它们的系统。但是，标准的SQL命令，比如"Select"、 "Insert"、 "Update"、 "Delete"、 "Create"和 "Drop"常常被用于完成绝大多数数据库的操作。MS SQL Server 就是用的Transact- SQL。SQL语言有着非常突出的优点，SQL语言是非过程化的语言、统一的语言、是所有关系数据库的公共语言。

If you have programming experience and a familiarity with C--the dominant lAnguage in embedded systems--Programming Embedded Systems, Second Edition is exactly what you need to get started with embedded software. This software is ubiquitous, hidden away inside our watches, DVD players, mobile phones, anti-lock brakes, and even a few toasters. The military uses embedded software to guide missiles, detect enemy aircraft, and pilot UAVs. Communication satellites, deep-space probes, and many medical instruments would have been nearly impossible to create without embedded software.
