摘　　要：传统的二层数据库应用模型已经越来越不适应现代企业应用需求变化快、分布性广的特点,具有跨平台、跨语言特性的CORBA技术正是构建三层应用理想的平台。本文结合本研究小组的有关项目,对在CORBA平台之上构建的CORBA应用模型、优点及困难,应用的事务控制、CORBA服务器设计、业务对象的安全等问题进行探讨。The traditional twolayer database application model doesn't adapt more and more to the features with desideration changing fastly and distributing wide of modern enterprise application.The CORBA technology with crossplatform and crosslanguage attributes is a ideal platform to create threelayer application.Combining referable projects of our research group,this paper discusses the applications model of CORBA,advantage and difficulty of it,the transaction control,CORBA Server design and security of business object within the platform of CORBA.
