摘　　要：分析了加速器系统中常用的二层数据库结构存在的不足。对正在开发的上海深紫外自由电子激光(SDUV-FEL)数据库系统进行了探讨,提出了一种基于公共对象请求代理规范(CORBA)组件技术、用C++构建中间件模型来实现三层数据库结构的方案,并用一个简单的磁铁信息的例子说明了CORBA组件的设计过程。In this paper, the drawback of usual two-tier database architecture was analyzed and the Shanghai Deep Ultraviolet-Free Electron Laser database system under development was discussed. A project for realizing the multi-tiered database architecture based on common object request broker architecture (CORBA) component and middleware model constructed by C++ was presented. A magnet database was given to exhibit the design of the CORBA component.
