摘要
在Windows 2 0 0 0操作平台上大型数据库应用系统的开发中 ,采用COM +作为中间件构成WindowsDNA三层体系结构逐渐成为流行的开发模式。先介绍了WindowsDNA结构和COM +体系结构、功能、原理 ;最后阐述了COM +结合MIDAS技术 ,以开发的人力资源管理信息系统为应用实例 ,说明了这种分布式多层结构带来的可扩展、易维护、易适应等优点。
In the developing of the large-scale database application system on the Windows 2000 operation platform, Windows DNA(Distributed Net Architecture) three-tiers structure using COM+, that acts as middleware, come to be the popular developing mode. The paper analyzes the structure of Windows DNA and the system architecture, function, principle of COM+, and illustrates how to develop the large-scale resource management application system using the technologies of COM+ and MIDAS.
