When you execute a rule, all of the tables that are created have a name made up of a prefix and a suffix.

在执行规则时，所创建的所有表都有由一个前缀和一个后缀所组成的名称。

Note that I've used the dw_ prefix on all tables in this article to distinguish them from other tables you might run across, particularly because authors and books are common table names.

请注意，本文中所有的表都使用了dw _前缀，以便于其他表区分开来，特别是authors和books都是很常见的表名。
