摘要
对CORBA分布式应用中构件间依赖关系的描述和依赖关系的动态更新进行了较详细的分析。在此基础上提出了一种面向图形的构件间依赖关系的描述方法,该方法把基于CORBA的分布式应用的体系结构视为一张逻辑图,在图上预定义一组操作,这有助于构件间依赖关系的描述和应用系统的动态配置。同时在CORBA之上实现了一个原型,概括地介绍了实现方法。
Based on the analysis of the dependency description of CORBA-based distributed applications and the dynamic update of de- pendency relationship,a graphic-oriented description method for component dependency description is put forward. The system architecture of a CORBA distributed application is viewed as a logic graph. A set of graphic operation is defined, which is beneficial to component dependency description and dynamic reconfiguration. A brief introduction to its practical implementation is provided.
