| 摘 要： | 管理信息系统通用部件要求能自动适应不同数据库、不同数据表的需要，在一个应用系统中往往根据客户的需要使用多种数据库系统，可是逻辑层的代码要想不作改动地从一个数据库系统切换到另一个数据库系统，在使用不同驱动程序及面对文本、图形、时间等类型数据时将会遇到很大困难．文中提出使数据库驱动对逻辑层代码透明的方案及屏蔽底层数据库的差异方法，用在MIS通用部件设计中取得良好效果．

| Abstract: | MIS general components are required to have the adaptiveness for different kinds of database and datasheet. A enterprise equipments appearance monitor management system can use various database systems according to different customers. However, while using different drivers and facing some types of data such as texts, graphics and time, it is so difficult for the code of logic layer to be switched from one database system to another with no change. A scheme that makes database driver be transparent for the code of logic layer is presented. The way that shields the difference of the bottom database is proved to have good effects in the design of MIS general components. |
