基于CORBA/Java的分布信息主动服务技术研究

On Active Operation and Security of Distributed Information Service

目前将分布对象计算技术引入 Internet/Intranet成为新的研究热点 ,形成了对象 Web体系结构。结合 CORBA与 Java的特性提出了一种新的对象导航模型 ONM(object navigationmodel) ,并利用该模型建立了分布信息主动服务 ,为 Web用户的信息访问提供了透明性、主动性和安全性。本文着重讨论了分布信息主动服务的对象导航模型、主动性以及安全防护机制。

The existing Internet application models have still some deficiencies in providing active operation and security. To reduce the effects of these deficiencies, a new distributed information active service system was presented, which is of two features, provision for active operation and three-tier security mechanism. Based on characteristics of CORBA and Java, a object navigation model (ONM) was proposed to build the distributed information active service, which utilizes the object reference to implement navigation between objects and support call for heterogeneous database. The architecture, active service, security protection and interface design were discussed.
