-·中国计算机报社</font></span></p> 在数据库编程中，不必要也不可能将应用程序操作的所有数据库字段放入一个数据库文件中。正确的数据库结构应是：将数据库字段放入多个数据库文件，相关的数据库都包含一个唯一的关键字段，在多数据库结构里可以建立联系。<br> 例如：要编制一个人事管理程序，为简化演示程序，只建立两个数据库，每个数据库都只建立两个字段。<br> <br> 个人简介 jianjie.dbf，由人事处维护；工资情况 gongzi.dbf，由财务处维护。<br> <br> 一、数据库的建立<br> 进入DataBase Desktop，建立数据库结构如下：<br> jianjie.dbf<br> 编号 字段名:bianhao size:4 type:number<br> 姓名 字段名:xingming size:10 type:character<br> <br> gongzi.dbf<br> 编号 字段名:bianhao size:4 type:number<br> 工资 字段名:gongzi size:4 Dec 2 type:number<br> <br> 注意：两个数据库的bianhao字段的size、type必须一致。实际上，两数据库文件可以分布在网络的不同计算机上，为便于演示，分别存为″c:\test\jianjie.dbf″和″c:\test\gongzi.dbf″。<br>⌨️ 快捷键说明
