摘　　要：分布式网络异构系统是未来分布式计算的典型网络结构,CORBA技术可以把复杂的底层通讯技术问题封装到对象内部,大大简化了开发的难度和成本。在保证通讯安全和效率的情况下,可以快速地改造现有的系统,使其符合现代网络环境下的C/S或B/S体系结构,满足多用户的共享,减轻客户端的负担。提出了基于CORBA的三层应用模型,分析了其运作机制和特点,给出了一个基于三层模型的项目实例,对其所采用的设计思路和关键技术进行了简要分析。Distributed network of isomerous system will be the typical construction of network in the future. The complicated communication can be encapsulated into object use of CORBA and it can simplify the exploitation and reduce the cost. While ensuring the safety and efficiency of communication, it can quickly reform the current system to make it suitable for the system of C/S or B/S, and can serve several users and lighten the burden of the client. Tri-tiered application model based on CORBA is brought forward, and their method and features in running are analyzed. Finally, a project example is given that is developed based on the 3-layer model, and the design consideration and the critical techniques used in the project are explained thoroughly.
