分布式信息共享环境中的信息合作模型

Information Cooperation Model for Distributed Information Sharing

提出了分布式环境下的信息合作模型 ,研究了基于CORBA/IIOP的分布式对象管理 ,包括分布式对象的定义 ,以区域为单位的对象管理体系结构 ,及相应的元数据管理·该信息合作模型提供了一个通用的和动态的方法 ,解决分布式环境下的信息合作问题·通用性体现在网络上任何节点都可以映射为不同的分布式对象 ,可以分别从属于角色层和信息层 ;动态性体现在该模型支持分布式对象的即插即用 ,不同对象具有不同的生命周期·目前 ,已应用到一个面向虚拟企业的信息集成系统ViaScope中·

The information cooperation model was proposed in distributed environment, e.g. virtual enterprise. And a CORBA/IIOP based distributed object management was designed. The design includes the definition of distributed object, the architecture for region object management and the associated metadata management. Region was adopted as a basic management unit of the global object management. The model provides a general and dynamic approach for information cooperation. It is general, because any node residing on network can be mapped into a distributed object which belongs to either role level or information level. It is dynamic, because each object may ask join in or withdraw from request from the cooperation model dynamically. Now, this model has been applied in a CORBA/IIOP based virtual enterprise information integrating system ViaScope.
