The following is an outline and description of the database tables created during the standard installation of WordPress at WordPress:Version 2.3.

Because WordPress interfaces with this database by itself, you as an end user, shouldn't have to worry much about its structure. If you're WordPress:Writing a Plugin, however, you may be interested in learning how to interface with the database directly. WordPress provides the wpdb Class to make this task easy.

Table Overview[ ]

This section is the overview of all the tables created during the WordPress standard installation. It is followed by specific information of what is in each table.


下面是在标准地安装2.3版本时，创建的数据库表格的大纲和描述。

因为WordPress自身与这个数据库向联系，你作为一名终端用户，不应该太多地担忧数据库的结构。 如果你正编写一个插件，你可能对怎样直接操作数据库，感兴趣。 WordPress提供了wpdb Class，使得操作数据库，这个任务变得简单。
