塞缪尔著
    关系数据库已经存在了30年，但他们不是原种的数据库，他们也不是最新的数据库。 XML和面向对象的数据结构在近几年已经发展。但是，关系数据库仍然是迄今为止最流行的数据库，并将于今后一段时间继续被人们所使用。
SQL是结构化查询语言的缩写，并且用于关系数据库。如题目，这篇文章只是在应用程序编程方面刚开始开发或者准备开发项目的载体。但是，这并不意味着这篇文章能给初学者关于SQL的一个清楚的介绍。这篇文章是给那些关于SQL有一些了解，并且想提高水平的读者读的。

XML and object-oriented data structures haveevolved in recent years. But relational databases are still by far the most popular kind of database available and will be for some time to come.
